Abstract

Geoconservation outcomes are hindered by highly subjective and conflicting criteria, varying assessment objectives, disparities in geoconservation strategy steps and the inadequate capturing and representation of geological data in dynamically changing inventories. Review shows that geoconservation outcomes are further hindered by the exclusion of quantitative geodiversity assessment from geoconservation strate- gies. A geoconservation toolkit is presented using the ArcGIS mobile apps QuickCap-

ture, Survey123 and Explorer to consolidate the steps in achieving geoconservation outcomes. The toolkit closed the theoretical gap between geodiversity assessment and geoconservation strategies and attenuated the discrepancies in geoconservation strategy protocols. Preliminary research suggests the inclusion of geodiversity in geo- conservation strategies will benefit geoconservation outcomes by providing scholars with a proxy to predict inventorying and geoheritage values, conservation exigencies and site complexity. The toolkit consolidated separate geoconservation strategies by unifying individual steps into one distinctive process leading to streamlined inven- torying, geodiversity and geoheritage assessment. ArcGIS QuickCapture facilitated challenges in managing dynamically changing inventories by providing a fast and streamlined approach to the capturing of geodiversity information and locations. ArcGIS Survey123 facilitated the amalgamation of steps in geodiversity and geoheri- tage assessment and inventorying. ArcGIS Survey123 also facilitated the introduction of a suitability analysis tool to objectively manage and select existing geoheritage and inventorying criteria. Subsequent research would augment this study and its findings by determining whether statistical correlations exist between geodiversity and associ- ated inventory and geoheritage values. Ensuing research would then seek expert ad- vice on the standardisation of which strategies, criteria, methodologies, and processes to include in an all-encompassing third-party mobile GIS application to complement the toolkit concept in this study.

Introduction Overview of Concepts

Geodiversity, geoheritage and geoconservation are interrelated concepts with distinctly differ- ent meanings and applications. Geodiversity is defined by Gray (2013) as “the natural range of geological, geomorphological, soil and hydrolog- ical features and more broadly includes its assem- blages, structures, systems and contributions to landscapes”. The assessment of geodiversity is a recent endeavour in the geosciences and is con- cerned with the evaluation of abiotic diversity (Forte et al. 2018). Geoheritage is used to describe the importance (Díaz-Martínez 2011) or quality (Pellitero et al. 2015) of the site and is the process of determining whether geodiversity has signifi- cant scientific, educational, cultural or aesthet- ic value (Díaz-Martínez 2011). The assessment of geoheritage is further broken up into multiple steps: an assessment of scientific values, added values, followed by an assessment of vulnerabili- ty, threats and risks to the site (Kubalikova 2013). The concepts ‘geodiversity’ and ‘geoheritage’ and their assessment, have been recognised as dis- tinctly separate research domains (Brilha 2015). Geoconservation is an action (Prosser 2013) with the intent of conserving geodiversity for its intrin- sic, ecological and geoheritage value (Sharples 2002). A geoconservation site, through an estab- lished process, the geoconservation strategy, is a site deemed worthy by the relevant authorities to achieve conservation status (Seijmonsbergen et al. 2009). There are several successive steps in- volved in listing a geoconservation site: invento- rying, qualitative or quantitative assessment using various methodological approaches (e.g. rank- ing techniques), conservation, interpretation and promotion (Brilha 2005). The inventorying stage is comprised of several steps that endeavour to ‘identify’ and ‘rank’ geosites based on their geo- heritage and significance criteria values. Geosites that do not comply with the established criteria are typically not deemed worthy of being listed for geoconservation purposes (Brilha 2015). There- fore, from these initial assessments and ranking,

the site’s conservation, interpretation, and promo- tion can be achieved (Brilha 2015, 2005).

We are in the midst of a sixth mass extinction (Leakey and Lewin 1996; Payne et al. 2016; Ceballos et al. 2017), evidenced by widespread environmental destruction and loss of habitats. Successful measures to avert this catastrophe rest on dramatically increasing and improving conser- vation efforts (Ceballos et al. 2015). Geoconser- vation is limited by the concept of ‘geodiversity’ which still has a marked conceptual weakness and is passing through a stage of methodologi- cal development and consolidation (Serrano and Ruiz-Flano 2007; Soms 2017). Achieving geocon- servation outcomes are probably further hindered by the separation of geodiversity assessment from geoconservation strategies (Brilha 2015). When geoconservation outcomes have been achieved, landforms, geological features, and soils (geodi- versity) have been successfully protected using es- tablished methodologies, such as the multi-faceted and sometimes subjective steps used in geocon- servation strategies.

Decision making and processes in the environmen- tal sciences are multi-faceted requiring the synthe- sis of a multitude of datasets, multiple stakeholders and sometimes subjective methodologies (Linkov et al. 2004). Similarly, achieving geoconservation outcomes is a multi-faceted endeavour requiring sometimes subjective methodologies (White and Wakelin-King 2014), disparities in geoconserva- tion strategy steps (Brilha 2015), and multiple out- put datasets from separate assessments. The dif- ferent steps in geoconservation strategies require using a variety of tools and methods to facilitate geoconservation outcomes; inventorying methods have been developed independently of geoheritage assessment methods and by extension geodiversity assessment methods (Brilha 2015), and therefore a range of separate methods and tools have ensued in geoconservation. Therefore, consolidating and streamlining existing methodologies may help to overcome some of the subjectivities and dispar-

ities in geoconservation strategies. Consider De Lima et al. (2010) who suggested that additional assessments in geoconservation strategies should be done at the same time as the geological assess- ment by the same team, and Crisp et al. (2020) who identified that mobile GIS applications could be used to unify geodiversity assessment meth- ods with geoheritage and inventorying protocols to better facilitate and streamline geoconservation outcomes. This study furthers that objective by using the three ArcGIS mobile apps QuickCap- ture, Survey123 and Explorer to consolidate the geoconservation strategy steps inventorying and geoheritage assessment, with quantitative geodi- versity assessment.

Mobile GIS Applications

The use of digital applications in conservation ef- forts has gained momentum and is now shaping conservation discourses and practices (Arts et al. 2015). The implementation of these technologies facilitates clear benefits to conservation science and its management (Arts et al. 2015; August et al. 2015; Pettorelli et al. 2014). For example, the digital applications ameliorate workflows, data accuracy and quality, and facilitate high standards in research results (Nowak et al. 2020). Further, the use of Geographic Information Systems (GIS) in mobile applications may provide significant re- ductions in cost and time (Iscan and Guler 2020), allowing data collection, monitoring and analyses to be simplified (Akhmetov and Aitimov 2015). Furthermore, digital applications facilitate im- proved data management capabilities, informa- tion access, visual representations and evidenced based decision-making (Arts et al. 2015).

Some benefits of mobile GIS applications are also evident in geoheritage, with some scholars having previously developed and proposed new innovations for each state of the heritage man- agement process. Fieldwork and the integration of results have previously been merged in current geoheritage methods using available GIS technol- ogies (Cayla et al. 2014; Martin et al. 2014). The

identification, assessment, mapping, and com- munication of spatial information are now being facilitated and improved by using mobile GIS applications (Ghiraldi et al. 2010; Gallerini et al. 2011; Cayla et al. 2012, 2014; Martin et al. 2014). GIS and web-mapping technologies have facilitat- ed the ‘communication’ of spatial information by developing geoheritage data visualisation inter- faces (Gallerini et al. 2011; Martin et al. 2014). Virtual field trip (Cayla et al. 2012) technologies have facilitated the ‘identification’ and digital field mapping tools have facilitated the ‘mapping’ of information in the field (Gallerini et al. 2011; Ghiraldi et al. 2010; Martin et al. 2014). These technologies have assisted the steps to understand, preserve and enhance geoheritage protocols.

Geographic information systems have been de- scribed as some of the best tools for geodiversi- ty assessments (Yongxin 2007), and by extension geoheritage management. Many multi-purpose mapping applications for mobile devices have emerged to facilitate open source spatial analy- ses and field surveys (Fan et al. 2019; Jolma et al. 2008; Nowak et al. 2020). ArcGIS Online is a recent and popular tool facilitating the storing of spatial data, creation of workspaces, spatial analy- ses, and the creation of maps (Nowak et al. 2020). One of the core tools driving the popularity of Arc- GIS Online is its ability to create workspaces that are compatible with multiple mobile applications researchers and conservationists can utilize in the field (Nowak et al. 2020). Examples of common mobile applications compatible with ArcGIS On- line are ArcGIS Collector, ArcGIS Survey123, ArcGIS Explorer, ArcGIS QuickCapture, ArcGIS Navigator and more. Scholars in other disciplines have previously used ESRI ArcGIS mobile appli- cations to facilitate their own research objectives. For example, Jordan et al. (2019) utilized the Arc- GIS Survey123 app to collect sociological data on tourism host community resident stress levels, and Lindsay (2014) proposed the benefit of mobile GIS apps to improve the efficiency and accuracy of fieldwork data collection in the field of archae-

ology. Lindsay and Kong (2020) subsequently developed a site survey workflow tool based on ESRI’s ArcGIS Collector mobile app to stream- line the capturing and storing of settlement survey data in Armenia.

Tasmanian Geoconservation Database Case Study and Mobile GIS Technologies

Many agencies that manage geoheritage have de- veloped their own online GIS tools and systems (Cayla et al. 2014). This case study considers Tas- mania, Australia, one of the earliest places in the world to develop the geodiversity concept (Kier- nan 1996; Kiernan 1997; Sharples 1993). Oracle database software is used to combine both textual and spatial data into a single database called the Tasmanian Geoconservation Database (TGD). The TGD information contained in the database is then housed in the Natural Values Atlas (NVA), a

web-based system for providing access to published information on natural values (https://www.natu- ralvaluesatlas.tas.gov.au/) (Comfort and Eberhard 2011). An online web interface, The Land Informa- tion Systems Tasmania (TheLIST), was developed to help users locate and find relevant information. TheLIST layer, geoconservation sites, is directly linked to the TGD which is an integrated GIS da- tabase of the state’s geodiversity and is a central re- pository for the storing of geodiversity information (Houshold and Sharples 2008) to assist land man- agers in the management of identified values. The TGD is facilitated and further developed by the Geo- diversity Conservation and Management team at the Tasmanian Department of Primary Industries, Parks, Water and Environment (DPIPWE) (Comfort and Eberhard 2011), with more refinements (DPIPWE 2016) that are still required (Table 1).

Consolidation using digital technologies has been

Table 1. The limitations and prospective refinements to be made to the Tasmanian Geoconservation Database (DPIPWE 2016).

a continuing trend in the establishment of the TGD used today (Fig. 1). Prior to the establishment of the TGD, there were about 12 comprehensive geological inventories associated with Tasmania’s geodiversity. For example, in 1979, the Geologi- cal Society of Australia (GSA) published a report entitled Geological Monuments of Tasmania, pref- atory to contemporary TGD processes used today (Eastoe 1979; DPIPWE 2016). However, the es- tablishment of the first TGD enabled the consol- idation of all 12 inventory documents or reports into one single digital database to facilitate geo- conservation management in Tasmania; attribute

information and spatial information were still separate. The attribute information was stored in a Microsoft Access Database, and spatial infor- mation was stored in an Oracle database (Fig. 1). Following a subsequent TGD system restructure, Oracle software was used to combine attribute and spatial data into one merged system now called the NVA (Comfort and Eberhard 2011). This provided more resourcing to facilitate fieldwork opportu- nities at existing or prospective geoconservation sites (Comfort and Eberhard 2011). Therefore, current trends have used digital technologies to consolidate and streamline the storage, represen-

tation, and accessibility of geoconservation in- formation on databases, the TGD (Fig. 1). In this study, we propose augmenting current consolida- tion approaches by further consolidating online databases with in-field processes, namely geocon- servation strategies and quantitative geodiversity assessment methods, which are methods used to evaluate or quantify the number or diversity of geological elements in nature (hereafter referred to as ‘geodiversity assessment’).

Through digital coalescence, the simultaneous use of ArcGIS mobile applications, we demonstrate the viability of a unified toolkit (hereafter, the ‘geoconservation toolkit’) in facilitating geocon- servation outcomes. Review of the TGD as a case study indicates the viability in using digital tools to consolidate online databases with geoconserva- tion strategies and geodiversity assessment. For example, even though information is now acces-

sible in one location, some relevant values are still missing from geoconservation sites with many bi- ases toward scientific values, attribute descriptions that are vague and brief, and many site boundaries still requiring verification (Table 1). Acquiring the information to update online databases, or list new geoconservation sites, is acquired from established geoconservation strategies such as in- ventorying and geoheritage assessment. Further, the output value from geodiversity assessments representing the quantity of hydrological, soil and other geodiversity elements (hereafter referred to as ‘geodiversity’) (Table 1), are considered a sep- arate research endeavour from geoconservation strategies (Brilha 2015). Therefore, we propose that through digital coalescence, geoconservation outcomes can be further consolidated by unifying geoconservation strategies with quantitative geo- diversity assessment.

Review shows that consolidating geoconser-

vation outcomes using digital tools may help to overcome current limitations in geoconservation strategies. For example, Brilha (2015) highlights that inventories of geodiversity are dynamic and readily change with advancements in scientific knowledge, with geosites losing or gaining geo- conservation status with the discovery of new geological phenomena. The proposed geocon-

servation toolkit could facilitate more rapid and streamlined inventorying of geosites. With more than 1000 geoconservation sites listed on the TGD, it is evident that a streamlined approach using digital technologies could be used to ex- pedite inventorying of geoconservation sites. In assessing the value of geodiversity (hereafter re- ferred to as ‘geoheritage assessment’), White and

Wakelin-King (2014) highlight that there is a mis- cellany of subjective and conflicting geoheritage criteria constraining the identification of relevant values of geodiversity. For example, the criterion integrity in the geoheritage assessment method considers the state of conservation of a site based on a scale of zero to one, with zero indicating de- stroyed and one indicating intact. Conversely, the method considers only the preservation status of essential geodiversity elements on a scale of zero to one, with zero indicating not preserved, and one indicating intact. There are numerous other exam- ples in the literature of varying geoheritage assess- ment criteria assessing the same values subjective- ly. A systematic approach was recommended by Brilha (2015) to overcome the misuse of termi- nologies and conflicting criteria in geoconserva- tion strategies, namely geoheritage assessment. A geoconservation toolkit approach would facilitate compiling existing geoheritage assessment crite- ria into a field-app for the user to systematically select relevant criteria to implement at the geosite in question (hereafter referred to as ‘Suitability Analysis’). The primary objective of geoconser- vation strategies is to identify, protect, and man- age valuable geodiversity (Brilha 2015), and yet geoconservation strategies and the assessment of geodiversity remain separate endeavors.

As demonstrated in this study, digital applications (hereafter referred to as ‘ArcGIS apps’) provide opportunities to bridge the gap between geocon- servation strategies and geodiversity assessment. This is because there are now many commercial mobile apps facilitating location-based data col- lection, attribute collection and enhanced data storage, processing, and presentation. Commercial apps such as ArcGIS are now offering significant versatility in their implementation across various disciplines. For example, the commercial ArcGIS app Survey123, offers significant customisability and an in-field user interface to suit the objectives of multiple research endeavors, in this case unify- ing geoconservation strategy steps and geodiver- sity assessment into a workable geoconservation

toolkit approach. Therefore, there is considerable viability, hence the recent uptake (Filocamo et al. 2020; Pál and Albert 2019; Pica et al. 2018; Williams and McHenry 2020), in adopting mobile ArcGIS applications to facilitate geoconservation outcomes in Tasmania and potentially elsewhere. Many mobile apps have been developed to suit the objectives of individual research projects (Nowak et al. 2020), and different ArcGIS apps although versatile are comprised of distinctive functional- ities. For example, AcrGIS QuickCapture is an app built to facilitate the rapid collection of field observations, and ArcGIS Explorer provides in- field access to pre-established digital maps. And ArcGIS Survey123 is an app facilitating field data collection through the creation, sharing and analy- sis of surveys. Therefore, we demonstrate the fea- sibility of combining these apps to unify geocon- servation strategies with geodiversity assessment to produce a geoconservation toolkit. Further, mobile GIS technologies allow the acquisition of more complex attribute information, validation of geoconservation boundaries and the identification and replacement of missing values. For example, mobile apps can aid in acquiring missing data or eliminating human error by providing users with predefined values to be entered directly in the field (Davidovic and Stamenov 2011). Further, spatial locations of individual geological elements are currently absent from the TGD, and geospatial data locations are paramount in facilitating better analysis, decision making and management in the environmental sciences (Davidovic and Stamenov 2011). Mobile GIS applications allow precision of geospatial data acquisition in the field (Davidovic and Stamenov 2011). And site data sampling by mobile GIS apps can provide more accurate de- scriptions of objects of interest.

Objective

This study trialled the simultaneous implemen- tation of three ESRI ArcGIS mobile applications QuickCapture, Survey123 and Explorer to close the current separation between quantitative geo- diversity assessment and the geoconservation

strategy, in a bid to consolidate geoconservation outcomes. This consolidated approach forming a ‘geoconservation toolkit’, was implemented at three north-west Tasmanian coastal geoconserva- tion sites as a case study. The TGD on the NVA was also used as a case study to show how mo- bile GIS applications could potentially benefit all existing geoconservation inventories and assess- ments globally.

Materials and methods Study Sites

Coastal areas are usually high in geodiversity (Brocx and Semeniuk 2009, 2010). Yet studies as- sessing geodiversity in these coastal environments are uncommon (Crisp et al. 2020). Therefore, three Tasmanian coastal geoconservation sites were selected for the implementation of the geo- conservation toolkit. To demonstrate the versatil- ity of the proposed toolkit, all three geoconserva- tion sites were of varying degrees of significance, geological type, representative values, scale, or relative age.

Don Heads Basalt Landform (State Significance) The Don Heads Basalt Landform geoconservation site (444007E, 5443266N) is located adjacent to the city of Devonport (445268E, 5442112N) on the north-west coast of Tasmania, Australia (Fig. S1). The geographical significance of the site has been identified at the state level (DPIPWE 2019). The site was selected for this study given its high educa- tion potential and proximity to a senior secondary college (Bradbury 2012). The site is also of signif- icant potential tourism value given its proximity to the only Spirit of Tasmania ship terminal in Tasma- nia. The site, an identified geological monument, was described by Eastoe (1979) as an excellent example of coastal landforms and basalt flow phe- nomena. Contiguous basalt flow phenomena have been observed further west (44080E, 5443195N) at Lillico Beach (Quilty et al. 2014). Given the site’s broad range of potential geoheritage values and sig- nificant geological phenomena, it was deemed suit- able for the implementation of the toolkit.

Mersey Bluff Pseudo Petroglyphs (Regional Significance)

The Mersey Bluff Pseudo Petroglyphs geoconser- vation site (445923E, 5443376N) in Devonport, Tasmania, is located a few hundred metres from the popular tourist destination, the Bluff beach (Fig. S2). The site was selected for its significant cultural and tourism potential. At the site, a range of dolerite rock carvings are once believed to have been carved by Tasmanian Aborigines, however, these carvings are more recently considered to be the result of distinctive root weathering on curvi- planar joints (Bradbury 1994). Further, there were no Aboriginal tribes believed to have inhabited the Mersey Bluff area (Plomley 1993). Despite the uncertainty around the origin of the petrogylphs, the site still exhibits significant cultural and tour- ism potential given the presence of the oldest Ab- original operated museum in Australia, Tiagarra. Therefore, given the site’s cultural and tourism potential it was deemed suitable for the implemen- tation of the toolkit.

Penguin Megabreccia (Global Significance) The Penguin Megabreccia geoconservation site (423193E, 5447989N) is situated less than one ki- lometer from the main tourist attraction centers of Penguin (Fig. S3). Situated close to Penguin are notable examples of coastal geology; Goat Island (426754E, 5447368N), Penguin Point (425967E, 5447712N), Ladders Point (426835E, 5447019N),

Tea Tree Point (424571E, 5447749N), Surf Club Point (422440E, 5448161N) and the Three Sisters Islands (426771E, 5447328N) located only 300m from the coastline. Therefore, this site was also selected for its potential to exhibit high aesthetic value. The megabreccia has previously been de- scribed as an ‘unusual’ phenomenon expressing the post-collisional, Middle-Late Cambrian ex- tensional phase of the Tyennan Orogeny in Tas- mania’s geological past (Bradbury 1994; Seymour and Vicary 2010), which is an example of the earliest phases of Gondwanan orogenesis (Moore et al. 2015). Therefore, the site probably exhibits some scientific value potential. Penguin was pre-

viously identified as a suitable location between 2005 and 2008 for the development of multi-sto- rey beachfront buildings. However, developments were circumvented by listing existing properties as heritage-listed sites. Therefore, this site was also selected for its potential to exhibit high con- servation value.

Data Collection and Arcgis Explorer Geological phenomena were noted using a novel randomized observation-based approach, or oth- erwise a site reconnaissance approach, where the sites were explored on foot while simultaneously collecting geological information without adher- ing to established transects. Given the variability in the shape of boundaries, following a transect might have meant that some geological phenom- ena were missed or unintentionally overlooked within each geoconservation boundary. Howev- er, existing inventories on the TGD were used as a guide to identify notable features at each geo- conservation site and such features were captured with the toolkit. To overcome potential naviga- tional barriers in the field such as adhering to and remaining within the geoconservation boundaries, the ArcGIS Explorer app was used. The Explorer app displays a real-time location in the field rela- tive to the boundaries. The ArcGIS Explorer app also provided the associated attribute information for each feature.

Consolidation One: Validation Boundaries

The boundaries of some larger geoconservation sites still require validation (Table 1). Through digital coalescence, the simultaneous use of all three ArcGIS mobile applications, site boundaries were validated while also collecting geodiversity, inventorying and geoheritage data. Shapefiles of validation boundaries were created using the Arc- GIS Online platform. Validation boundary shape- files were established by using aerial imagery, and by identifying geological features or landforms located outside of the existing geoconservation boundaries. ArcGIS Explorer facilitated in-field viewing of the validation boundaries and subse-

quent amendments where required.

Consolidation Two: Determination of Suitable Geoheritage Criteria

A comprehensive list of existing criteria used by geoheritage scholars was compiled by carrying out a literature search of current geoheritage as- sessment publications in Scopus (Table S2). The search to pinpoint relevant literature containing the criteria was refined by using the inbuilt ad- vanced search functionality tools (Table S1). The Scopus search returned 130 articles, but only 80 were used to find currently used criteria. The 50 excluded articles were irrelevant, unable to be ac- cessed or did not contain geoheritage assessment criteria. Finally, a total list of 130 existing geoher- itage assessment criteria was compiled and subse- quently used in the geoheritage assessment. The suitability or relevance of geoheritage criteria for the assessment of the site was determined using five disparate ranking standards (Fig. S4).

Relevance of the criterion to the geoconserva- tion site was used to eliminate irrelevant criteria. Rarity of the criterion was used to distinguish frequently from seldom used criteria by tally- ing each criterion. The logic was that frequently used criteria were based on the experts’ opinion given their repetitive use in scholarly articles and so were probably suitable to implement at most geoconservation sites. Relevance of the criteria to existing TGD protocols was considered to select criteria relevant to or currently used by industry professionals at DPIPWE to list geosites. This ensured that the rapid geoheritage assessment method adhered to and supplemented existing TGD protocols. To support the rapid geoheritage assessment approach, a standard entitled replica- bility of the criterion was established. This stan- dard ensured that criteria were selected that were not time-consuming or difficult to implement. For example, the criterion vicinity to urban networks would rank lower in this standard than the crite- rion integrity given that the former would require a step to determine the geographic position of the

site to other towns and cities. And finally, the stan- dard relevance of criteria to the grouped values was established to rank criteria associated with relevant values higher than those associated with irrelevant values. For example, at a site where sci- entific value is of higher relevance than all other values, the associated criteria with this value were more likely to be selected to assess the site given its higher-ranking value.

Consolidation Three: Inventorying Inventorying was facilitated by using the stand- alone desktop version of Survey123 Connect. The survey was generated based on the inbuilt Advanced XLSForm template. The inventorying approach was developed based on the inventory- ing method set out in Brilha (2015). Step 1 (Fig. S5A) is the first tab available to users and is the first stage of the inventory process. An area clas- sification was first allocated based on the size of the geosite, followed by an allocation of site type (Fig. S5B). The site type allocated determined which criteria were used to complete the inventory (see Brilha 2015). The first step also required that a literature review of the study site be completed. Relevant criteria will not appear in the inventory for evaluation unless Step 1 has been answered as ‘yes’. Subsequently, the criteria for the inventory were ranked from one to four (Fig. S5C).

Consolidation Four: Geoheritage Assessment Geoheritage assessment was facilitated by using the standalone desktop version of Survey123 Con- nect. At the top of the home page (Fig. 2A), an image of the proposed suitability analysis (Fig. S4) was provided to guide the selection of rele- vant criteria to be used to determine site signifi- cance and rank geoheritage criteria. In step one of the app, relevant values were selected (Fig. 2A). Subsequently, selected values and their associated criteria (Table S2) were appended to the lists in Survey123 as step two (Fig. 2B). The suitability of each criterion was then ranked from 0 – 10 using the provided suitability approach (Fig. S4). Cri- teria with a score of nine or ten were then used

in step 3 of the geoheritage assessment (Fig. 2C) to determine the overall significance of the site. The levels of significance used were based on those proposed by Sharples (2003) and currently used by DPIPWE (2018) on the NVA. The meth- od of determining site significance was based on the approach used by Grove et al. (2015) where highly relevant criteria or values (a score of nine or ten) were given a rank from Sub-Regional to Global. Following the determination of site sig- nificance, relevant geoheritage criteria were then ranked from 0 – 4 (Fig. 2D) and the results were averaged to determine overall scientific, touristic, educational, and cultural value. The ranking of criteria to determine geoheritage significance has been widely adopted by many scholars (Bruschi et al. 2011; Rovere et al. 2011; Ovreiu et al. 2019).

Consolidation Five: Calculation of Geodiversity The geodiversity assessment approach used in this study was developed based on the Serrano and Ruiz-Flano (2007) geodiversity index formula, a widely implemented approach by other scholars (Pellitero et al. 2011; Manosso and de Nobrega 2016; Chelariu and Hapciuc 2017; Kaskela and Ko- tilainen 2017; Ozsahin 2017; Perotti et al. 2019). The geodiversity index formula proposed by Serrano and Ruiz-Flano (2007) is as follows:

(1)

where Eg = Count of different geodiversity ele- ments, R = roughness coefficient and S = surface area of site of interest (km2)

The Serrano and Ruiz-Flano geodiversity index was implemented at each study site (Serrano et al. 2009)Spain. This approach was deemed suit- able as it facilitated the geodiversity assessment of territories containing various characteristics. This approach also facilitated the comparison of geodiversity between territories and different geo- graphical areas. The parameter Eg was determined by counting the points captured by the feature class Geodiversity Index Point in the ArcGIS

B) Criteria within each selected value (Step 1 – Geoheritage Values) were ranked from 0 to 10 based on the suitability analysis image. C) All criteria with a rank of nine or higher were selected for the significance assessment in Step 3. Each criterion was assigned a significance value and then an overall significance value was subsequently determined. D) Criteria were ranked from 0 to 4 based and then an overall geoheritage rank value was determined.

QuickCapture software. The parameter Eg was determined by counting the physical elements as lithology, geological structures, geomorphol- ogy, morphostructures, erosional landforms, hydrological, pedological and the presence of micro-landforms of interest. Repetitions of phys- ical elements were not counted. To calculate R, digital elevation models (DEMs) in raster format (.tif) were extracted from the website ELVIS-El- evation and Depth – Foundation Spatial Data

<https://elevation.fsdf.org.au/>. A polygon was drawn around each area of interest (Figs. S1, S2, S3) on the website, and 1 meter DEMs were

subsequently downloaded and imported into Arc- Map software. The raster DEMs were converted to slope values using the inbuilt Slope (3D An- alyst) tool. The dominant slope was determined by using the average of the slopes calculated in ArcMap, the average slope was then used to de- termine a roughness value (Table 2). Surface area

(S) was determined by using the calculate geom- etry tool in ArcMap. The output Gd values from Survey123 for each boundary were then catego- rized into respective geodiversity classes (Table 2). The R value is used as a proxy of the surface roughness of the area at each site. The null hy-

pothesis is that when the surface is rougher there is higher variability of landscape elements, and hence geodiversity increases. The determination of roughness values from a DEM was associated

with the first inventorying step for each site, the literature review.

Consolidation Six: Geodiversity Assessment Using QuickCapture and Survey123

In ArcGIS Online, relevant point feature layers were initially created for subsequent importing into AcrGIS QuickCapture. The point features were entitled ‘Geodiversity index point (ER)’, Geological structures’, ‘Erosion/accumulation landforms’, ‘Landform’, ‘Soil and stratigraphy’, ‘Pedological’ and Hydrological (Fig. S6A-B). To facilitate ‘rapid’ capturing of data in the field a de- scription attribute was the only field required to be populated. However, to ensure that descriptions remained consistent across each captured feature, a hint was provided underneath each field. For example, a description of type, classification, rep- resented ages, colour, grain size and flow charac- teristics was required for each geological structure point (Fig. S6C). In Survey123 the geodiversity assessment data was configured to request data based on the number of geoconservation or vali- dation boundaries (Fig. S6 D-F). For example, a site with one validation and one geoconservation boundary would require an R1, Er1 and S1 value to be populated for the geoconservation bound- ary (Fig. S6E), and one R1, Er1 and S1 value for the validation boundary (Fig. S6F). Further, a site with two geoconservation boundaries required the population of an R2, Er2 and S2 value; these val-

ues would increase depending on the number of boundaries. Furthermore, the calculation of geodi- versity was automated in the Survey123 field app by using the calculate tool in the XLS Form func- tion in the preliminary stages of constructing the app. At this point, using Survey 123 and Quick- Capture the inventorying, geoheritage assessment and geodiversity assessment were amalgamated and streamlined into one ‘toolkit’.

Geodiversity Assessment Data

Site 1 showed the highest geodiversity compared to other sites, with a value of 43.7 (Table 4) (Fig. 3). Given the high ER, S and R value in the valida- tion boundary at Site 1, there is evidence to suggest that the two existing geoconservation boundaries (G1-2) could be amended on the TGD (Fig. S1). Further, the value of geoheritage at Site 1 ranks the highest for scientific and educational value, followed by tourism and conservation (Fig. S10). Site 2 has the lowest geodiversity compared to the other coastal sites, with a value of 1.22 (Fig. 3). The validation boundaries at site 2 are quite dis- similar to the existing G1 boundary. Interestingly, V1 has the highest ER count at the site, and there- fore, there is evidence to suggest V1 and G1 could both be reflected in the TGD (Table 4)(Fig. S2). A further assessment of geoheritage suggests that V1 could be added to the TGD for educational, cultur- al, tourism or conservation value (Fig. S10). The geodiversity within the geoconservation boundary at Site 3 was also quite high, with a value of 40.5 (Fig. 3). The validation boundaries at Site 3 are also like the existing G1 boundary, given the sim- ilarity between values of R, ER and S. However,

the geodiversity within the validation boundaries are considerably less overall, having attained me- dium to low geodiversity (Table 4)(Fig. S3). Site 3 ranked the highest in aesthetic value compared to other sites, and lowest in conservation value. The scientific value at Site 3 is equal to the scientific value at Site 1 (Fig. S10).

ArcGIS QuickCapture facilitated capturing the spatial location of geological features, geormor- phological landforms, hydrological elements, soil, stratigraphy, number of physical features and ero- sion and accumulation landforms (Fig. S8). The geological features were diverse and consisted broadly of elements such as tessellated pavement, foredune basalt outcropping, xenolith, joints, cliffs, and stacks (Table 5). Hydrological elements consisted of leaching aquiferous water, land over- flow and rocky pools. Erosional landforms were mostly the result of weathering from the Bass Strait such as undercutting of basalt, or honey- comb weathering from the influence of salt. Ac- cumulation landforms were uncommon, however, were mostly observed in deposition zones where both xenolith and sand were deposited. Soil was

Digital elevation models and slopes to calculate roughness (R) were facilitated by ELVIS data (ICSM, 2020).

also uncommon and was observed predominant- ly at the base of foredunes. Further, stratigraphy was more common than soil and was observed in areas of the coast where there appeared to have been successive volcanic events resulting in a dis- tinctive layering of basalt rocky shores (Table 5).

A range of geological features are spread out across about 2 km of coastline at Site 1 (Fig. S8) and G1, G2 and V1 contain a variety of geological features. The G1 and G2 boundary are predom- inantly made up of erosional and accumulation landform features, geomorphological and generic

geological structures (Table 5). Conversely, V1 is predominantly hydrological and geomorphologi- cal features. Site 2 (Fig. S7) is interspersed with a range of geological elements, but few hydrolog- ical elements. The site is predominantly made up of geological structures, with some erosional land- forms closer to where the basalt meets the ocean

(Table 5). Site 3 (Fig. S7) extends over about 4 km, is interspersed with all geological feature types assessed. The entirety of the study site, even outside G1 maintains a relatively high number of individual geological features. Both erosional ad hydrological landforms and features were pre- dominant across the whole site (Table 5).

Table 5. A summary of geological data types captured at each geoconservation site from within the established geological data classifications used to capture geodiversity in ArcGIS QuickCapture.

Each point feature captured in the field stored at- tribute information relevant to the geodiversity elements at the site. To demonstrate (Fig. S9), a geological structure point feature stored a pho- tograph attachment, description, rock type, rock classification and represented ages attributes. The above attributes were captured for every point fea- ture captured within each of the geoconservation sites. Furthermore, this data would readily merge and align with existing databases, namely Oracle used in the NVA (Connect to Oracle from Arc- GIS, https://enterprise.arcgis.com/en/server/latest/ manage-data/windows/connect-oracle.htm). Fur- ther, the extensive attribute information captured in Survey123 (Tables S3, S4) could be imported into GIS software and spatially joined to individu-

al geological feature classes (Fig. S9). Or an over- arching geoheritage feature class point containing geoheritage value attribute information could be uploaded to and added at all existing geoconser- vation sites (Fig. 4).

Geodiversity and Geoheritage Inventorying Toolkit Compared to NVA Data

Output data from ArcGIS QuickCapture and Sur- vey123 was compiled and uploaded to ArcGIS Online (Fig. 4). The data uploaded to ArcGIS Online contained geodiversity data and associat- ed attributes from ArcGIS QuickCapture for each of the three sites (Fig. 4). Further, geoheritage and inventorying data and associated attributes from Survey 123 (Table S4) (Fig. 4) were easi-

ly accessible and were subsequently joined with captured spatial geodiversity points (Fig. 4). By using ArcGIS QuickCapture, considerably more information was accessible about individual geo- logical elements and geodiversity at each of the sites (Fig. 4), compared to what is currently shown on the NVA, a geoconservation boundary with no point features indicating location of geodiversity elements and associated attributes (Fig. S11A-C). However, the NVA did include some data showing a photograph of a geodiversity feature of interest, with some associated attributes (Fig. S11B). The NVA also included information about potential threats, management, condition, conservation, physical, bedrock and geosite values (Fig. S12). However, all values displayed on the NVA were qualitative in nature with no ranking values for geoheritage or inventories (Figs. S11, S12). Con- versely, through the digital coalescence of all mo- bile applications, a suitable qualitative and quan- titative inventorying and geoheritage assessment was implemented and spatially aligned at each geoconservation site (Figs. 3, S9, S10, S13). This data could be exported and subsequently merged with the NVA database, and subsequently dis- played on TheLIST.

Discussion

Geoconservation Toolkit Concept

Geoheritage inventorying and assessment are early steps in geoconservation strategies used to facilitate geoconservation outcomes, and geodi- versity assessment is currently a separate research endeavour altogether (Fig. 5A) (Brilha 2015). Each step in the geoconservation strategy has varying objectives, methods and techniques (Fig. 5B); however, the overarching objective of geo- conservation strategies is to conserve geodiversi- ty within geosites (Henriques et al. 2011), yet the assessment of geodiversity remains separate (Fig. 5B). Through digital coalescence (Fig. 5C), geo- conservation outcomes were consolidated by clos- ing the gap between geoconservation strategies and geodiversity assessment. Digital coalescence also facilitated the streamlining of methods and

techniques between individual geoconservation strategy steps (Fig. 5C).

ArcGIS QuickCapture facilitated the quantita- tive calculation of geodiversity, and in acquiring the spatial location and descriptions of abiotic elements (Fig. 5C). ArcGIS QuickCapture was used to determine the ER value in the Serrano and Ruiz-Flano (2007) geodiversity index formula (Table 4), denoted in the app as ‘geodiversity in- dex point (ER)’ (Fig. S6A). The interface within ArcGIS QuickCapture (Fig. S6) provided a sim- ple push-button approach to capture the spatial location of geological structures, erosional and accumulation landforms, soil and stratigraphy and hydrological elements (Table 5)(Figs. S7, S8) and facilitated in-field descriptions of individual geo- logical elements (Figs. S6C, S9). ArcGIS Explorer facilitated in-field navigation and amendments to boundaries (Fig. 5C). There were no distinctive boundary delineations in-field for each geocon- servation site, and so ArcGIS Explorer provided real-time positioning information to remain with- in the validation and geoconservation boundaries (Figs S1, S2, S3) while collecting geological data (Fig. 4). Therefore, the combined use of ArcGIS QuickCapture and Explorer enabled efficient and accurate capturing of geological features and de- scriptions while remaining within established boundary delineations (Fig. 5C).

ArcGIS Survey123 facilitated in-field calculation of geodiversity and geoheritage value, invento- rying, geoheritage criteria selection and attribute information storage (Fig. 5C). When the parame- ters of the Serrano and Ruiz-Flano (2007) formula (ER, R and S) were populated in Survey123, an output value for geodiversity was automatical- ly calculated in-field (Table 4). With the coales- cence of ArcGIS QuickCapture and Survey123, geodiversity was readily determined in-field. Survey123 also facilitated the streamlining of the two geoconservation strategy steps inventorying (Fig. S5A-C) and geoheritage assessment (Fig. 2) into one workable tool. Survey123 also pro-

vided a streamlined and systematic approach to determining suitable criteria to implement at each geoconservation site (Table S2)(Fig. S4). Further, selected criteria from within Survey123 were then used to assess each geoconservation site, another approach streamlined and facilitated by the Sur- vey123 app (Fig. 2). The geoheritage value of each geoconservation site was automatically calculated in-field (Fig. S10). The combined use of ArcGIS QuickCapture and ArcGIS Survey123 facilitated storing attribute information about the number of features, geodiversity values and quantitative geo- diversity assessment outputs (Fig. 5C). Therefore, through digital coalescence (Fig. 5C), the dispari- ties in and the separation between geoconservation strategy steps were streamlined into one workable tool (Figs. 2, S5, S6), geodiversity assessment was consolidated with geoconservation strategies (Ta- ble 4)(Fig. S13) and detailed in-field capturing of geoheritage and inventory values were facilitated (Fig. 4).

Consolidated Geoconservation Outcomes

The inspiration for the proposal of a unified ‘tool- kit’ in geoconservation stems from current trends in biodiversity assessment. There is an intrinsic relationship between biodiversity and geodiversi- ty, yet the first is more widely disseminated in the literature (Santos et al. 2017). Biodiversity assess- ment indices are now being transformed and used in geodiversity assessment methods (Pellitero et al. 2015). Therefore, it is not unreasonable to sur- mise that biological conservation protocols can be translated into geoconservation strategies, and by extension benefit geoconservation outcomes. For example, in the biological sciences, species rich- ness is assumed to be an indicator of conservation value (Meir et al. 2004). Therefore, ecologists have put considerable effort into determining and monitoring species richness to conserve biodiver- sity, since conserving locations with high species richness is an efficient method to conserve biodi- versity (Fleishman et al. 2006), in some scenarios. It is recognized now that areas of high geodiversity harbor higher biodiversity (Zarnetske et al. 2019).

By extension, areas of high geodiversity are likely locations with many geoheritage and inventorying values (Tables 4, S4). Conversely, areas of low geodiversity probably have fewer geoheritage or inventory values (Tables 4, S4).

The quantitative assessment of geodiversity is the evaluation of abiotic elements using quantita- tive methods such as the Serrano and Ruiz-Flano (2007) index. These methods produce output nu- merical values indicating the ‘diversity’ of geo- logical elements (Table 4). Therefore, like species richness in biological conservation, knowing a geodiversity value through geodiversity assess- ment will provide a multitude of benefits to geo- conservation (Fig. 5). The current approach used by scholars in geoconservation strategies is to subjectively rank geodiversity based on the num- ber of geological phenomena counted; for exam- ple, Pereira et al. (2015) used a ranking approach from 0 to 4 to allocate a geodiversity value for the Iberian Massif Landscape in Portugal. A value of four was allocated when a geosite contained three or more types of geological features with scientif- ic relevance, while zero was allocated when only one type of geological feature was present. There- fore, more dimensions of quantitative geodiversity assessment may complement geological diversity criterion with a systematically determined geodi- versity value (Table 4).

Site 1 showed the highest geodiversity (Table 4) (Fig. 3) and using QuickCapture, more points were captured at the site (Fig. S9). Preceding invento- rying steps (Fig. S5B) suggest the site is an ex- cellent example of basalt flow phenomena (Eastoe 1979). A succeeding geoheritage assessment step (Fig. 2) revealed that the site is of high conser- vation value relative to the Penguin Megabreccia geoconservation site (Fig. S10). All boundaries at this site were high in individual geological struc- tures, erosional and accumulation landforms, and geomorphological elements (Table 4)(Fig. S13). The high scientific and conservation value of this site could probably be linked to its high geodiver- sity (Table 4)(Fig. S10). Therefore, a viable focus

Figure 5. A conceptual model indicating how the digital coalescence of three ArcGIS mobile apps consolidates quantitative geodiversity assessment with geoconservation strategies. A) Geodiversity and geoheritage assess- ment and inventorying are distinctively separate steps. B) Inventorying and geoheritage assessment in the geoconservation strategy are currently separate research endeavors from quantitative geodiversity assessment.

of subsequent research would be to determine whether a correlation exists between the level of geodiversity and specific geoheritage assessment criteria such as scientific, potential threats, con- dition, or conservation value. To demonstrate the benefit of establishing a correlation between geo- diversity and geoheritage values, consider for ex- ample a site deemed rare, vulnerable and in bad condition with low geodiversity and how it should perhaps be given priority conservation given the relatively low number of abiotic elements. Con- versely, a vulnerable site with high geodiversity is potentially less urgent. Subsequent geoscien- tific research is needed to further validate how to interpret geodiversity values in geoconservation strategies. Experts might agree that a geodiversi- ty value in a geoconservation strategy is a proxy for rarity or scientific value at a site (Table 4, S4). To demonstrate, Site 1 and Site 3 were higher in geodiversity than Site 2, with Site 2 exhibiting no scientific value (Table 4)(Fig. S10).

There are other potential benefits the inclusion

of geodiversity assessment in geoconservation strategies may have on geoconservation out- comes. High geodiversity may indicate the need to include broad inventorying criteria and the need to regularly update data contained within the in- ventories given the higher complexity at the site (Tables 4, S4)(Figs. 3, S13). Low geodiveristy might indicate the need to utilize fewer compre- hensive inventories with relatively simple criteria that are required (Tables 4, S4). High geodiver- sity may also indicate the need to include highly varied geoheritage criteria with a specific focus on scientific values (Table 4)(Figs. 5, S10, S13). Conversely, low geodiversity may require more specific and less complicated geoheritage assess- ment criteria such as education value given the potentially lower interpretation potential at the site (Table 4)(Figs. 5, S10, S13). Therefore, the inclusion of quantitative geodiversity assessment in geoconservation strategies may serve as proxies for geoheritage assessment criteria, comprehen- siveness of inventories and facilitation of succes- sive geoconservation strategy steps (Fig. 5). With

this study providing preliminary data in support of an established link between geodiversity and in- ventorying and geoheritage values (Table 4)(Figs. S9, S10, S13), subsequent research could deter- mine whether mathematically proven links exist between the concepts using statistical approaches. Preliminary data suggest the following benefits to geoconservation outcomes (Fig. 5):

• Predicting sites with rapidly and dynamical- ly changing inventories: areas with high geo- diversity are probably more likely to require regular inventorying to continually monitor the many features present at each site (Table 4) (Figs. S10, S13).

• Identifying sites of high scientific value: sites with high geodiversity are potentially high in scientific value (Table 4)(Fig. S10)

• Predicting the ‘extinction’ of rare abiotic fea-

  tures: sites with low geodiversity, rare and vul- nerable features, deserve priority conservation since the geology in that local area is limited (Table 4)(Fig. S10)

• Low interpretation potential: sites with high

  geodiversity probably have lower interpreta- tion potential and therefore probably have low- er educational value (Table 4) (Fig. S10)

• High accessibility: low geodiversity might in-

  dicate reasonably high accessibility across the research site given potentially lower rough- ness of the terrain (see Serrano and Ruiz-Flano 2007 formula) (Table 4).

  
  

  Enhancing Geoconservation by Facilitating Com- prehensive and Dynamic Inventories, Inventories are dynamic and best be regularly updated. With the rapid rate at which scientific knowledge ad- vances, current geosites may also lose allocated values overtime, or new phenomena may promote the gain in geosite status (Brilha 2015). For exam- ple, geodiversity sites continually evolve such as changing river channel shapes, or climate change impacts (Prosser et al. 2010). The geoconserva- tion toolkit developed in this study provided fast, efficient, and facilitated geoheritage and geodi-

  versity inventorying (Table S4)(Figs. 2, S9, S13). The streamlining of strategy steps facilitated by the geoconservation toolkit provided an expe- dited, methodical, and streamlined approach to re-assess and inventory existing geoconservation sites (Table S4) (Figs. S6, S8, S10, S11, S12). The implementation of the proposed geoconservation toolkit helped to facilitate overcoming the chal- lenges faced by scholars, industry professionals and conservationists in maintaining and manag- ing dynamically changing inventories of geosites (Figs. S10, S12).

  
  

  In some countries, geoheritage management is hindered by limited updating of comprehensive inventories (de Lima et al. 2010). Consider the TGD, where some geoconservation sites are up- dated every few years, with Site 1 (Fig. S1) receiv- ing its last condition or conservation assessment in March of 2014 (Fig. S12), a timeframe of six years for active processes and other factors such as new knowledge in the discipline to render the site’s current record incorrect. The geoconserva- tion toolkit supported more comprehensive in- ventorying (Table S4)(Figs. 2, S1, S10, S13) by facilitating the rapid capturing of spatial location (Fig. 4) and attribute information of geodiversity data (Fig. 4). Conservation efforts in the biologi- cal sciences can be constrained by the absence of the spatial location of biological data (dos Santos et al. 2019; Parks and Mulligan 2010). Acquiring spatial data of geological elements will benefit the management of existing geosites by facilitating the rapid monitoring and updating of inventories (Table S4)(Fig. 4) established steps in the geocon- servation strategy (Brilha 2015). To demonstrate, acquiring the spatial location of geodiversity fea- tures has benefited the field of geotourism by pro- viding tourists with the capacity to visualize, lo- cate, interpret, and record geological phenomena more readily (Dias et al. 2004).

  Effective geoheritage management is constrained

  by the implementation of inadequate geoheritage and inventorying criteria (de Lima et al. 2010). Geoheritage management is further hindered by

  the many highly subjective and conflicting criteria (White and Wakelin-King 2014). Some scholars have implemented inventories that have produced incorrect criteria, with some ranking subjective criteria such as accessibility at a site deemed to have high scientific relevance (Joyce 2010). The suitability analysis included in the geoconserva- tion toolkit will provide the basis to objectively determine the most relevant geoheritage and in- ventorying criteria to implement at existing, or proposed geosites (Table S2)(Fig 4. S4). It is ex- pected this approach will eliminate the selection of unsuitable criteria in ensuing site assessments (Table S2).

  
  

  Current Research, Limitations, and Future Di- rections

  The geoconservation toolkit proposed in this study marks the conception of a novel approach working to close the gap between quantitative assessment and geoconservation strategies. ArcGIS mobile apps and the TGD were used to demonstrate the viability of the proposed toolkit to geoconserva- tion outcomes. It is anticipated that this paper is the first of many expanding on objectives to con- solidate and streamline geoconservation outcomes using digital tools. Subsequent research could consult geoscientific app developers (Williams and McHenry 2020) to develop an accompani- ment or replacement third-party app to the ArcGIS apps, which is designed specifically for the con- solidation of geoconservation outcomes. There are several current limitations to using ArcGIS apps to facilitate ongoing consolidation of geoconser- vation outcomes:

  
  

• ArcGIS Online is not a freeware application and a subscription with ESRI is required to ac- tivate the online features associated with this tool

• ArcGIS Survey123, QuickCapture and Ex- plorer are directly linked to ArcGIS Online accounts and a subscription is also required to use these apps

• The ArcGIS tools have not been developed to

  meet the needs of the geoscientific community and hence, there may be some limitations to the software itself in its ability to meet individual requirements. For example, no ArcGIS mobile application facilitates the automated calcula- tion of a ‘roughness index’ without prior inter- vention using other software such as ArcMap and ELVIS

• These applications although user-friendly, re-

  quire some GIS expertise to initiate and merge with existing databases. Utilising these appli- cations may be difficult for those with a limited GIS software knowledge base

• The geoconservation toolkit in this study uses

three ArcGIS mobile applications, posing a challenge having to simultaneously manage up to three separate apps.

This study has amalgamated quantitative geodi- versity assessment with the assessment and in- ventorying of geoheritage. Subsequent research should endeavor to amalgamate latter processes in the geoconservation strategy into a mobile app; conservation, interpretation, and promotion (Bril- ha 2005). Filocamo et al. (2020) has suggested fu- ture directions for the implementation of mobile GIS applications in facilitating geoconservation outcomes (Table 6). To emphasize the current limitations and benefits of using ArcGIS Online mobile apps in the geoconservation toolkit, the findings from using the ArcGIS mobile apps with the recommendations from Filocamo et al. (2020) were compared.

Table 6. Filocamo et al. (2020) made a series of recommendations of what mobile GIS applications should include when used in the field of geoconservation. To demonstrate the viability of our ‘geoconservation toolkit’ concept we compared our findings from implementing the apps.

Scholars have previously referred to the benefit of mobile applications for geosite interpretation and promotion (Barisic 2011; Cayla et al. 2014; Dias et al. 2004; Frey and Hinkelmann 2009; Martin et al. 2014), and potential benefits are demon- strated of combining quantitative geodiversity as- sessment with geoheritage and inventorying pro- tocols to geoconservation outcomes (Crisp et al. 2020). This study augments the work of Crisp et al. (2020) by developing a geoconservation tool- kit approach where the gap between quantitative geodiversity assessment, geoheritage and inven- torying has been closed. This study could also complement current research investigating the use of modified mobile apps to facilitate qualitative field assessments in geoconservation and geotour- ism (Williams and McHenry 2020; Filocamo et al. 2020; Pica et al. 2018). Given that this study has demonstrated the viability of using digital ap-

plications to bridge the gap between geodiversity assessment and geoconservation strategies, subse- quent research may benefit from exploring wheth- er digital applications could be used to bridge the gap between geodiversity and biodiversity assess- ment, with many scholars still treating them as separate entities in the literature (dos Santos et al., 2020; Matthews, 2014; Crisp et al. 2020).

Conclusion

A geoconservation toolkit is presented using the ArcGIS mobile apps QuickCapture, Survey123 and Explorer to consolidate geoconservation out- comes. The geoconservation toolkit closed the theoretical gap between geodiversity assessment and geoconservation strategies and attenuated the discrepancies in geoconservation strategy proto- cols. ArcGIS QuickCapture facilitated challenges in managing dynamically changing inventories by

providing a fast and streamlined approach to the capturing of geodiversity information and loca- tions. ArcGIS Survey123 facilitated the amalga- mation of steps in geodiversity and geoheritage assessment and inventorying and ArcGIS Sur- vey123 facilitated the introduction of a suitability analysis tool to objectively manage and select ex- isting geoheritage and inventorying criteria. This study has shown that amalgamating geodiversity assessment with geoconservation strategies may help to predict sites with rapidly and dynamically changing inventories, facilitate the identification of high scientific value sites and help to predict the extinction of locally rare and vulnerable abi- otic features. The geoconservation toolkit in this study facilitated an expedited and streamlined approach to geoheritage and geodiversity inven- torying of spatial and attribute information of geo- logical data. The acquisition of location data for individual geological phenomena will benefit pol- icymakers, conservationists, and scientists in the management of existing geosites by facilitating updates to dynamically changing inventories and by facilitating successive steps in the geoconser- vation strategy such as monitoring.
