The study was conducted in the Butana region of Sudan to assess the impact of climate change on the browse trees/shrubs cover and production in the Butana rangelands. Five meteorological stations surrounding Butana were selected to represent the region’s climate. Simple regression analysis was used to analyze the trend of climate variables (rainfall, temperature). The […]
Aromatic and medicinal plants are a rich source of substances that are beneficial to human health. At a socio-economic level, the exploitation of medicinal plants constitutes an important income for the local populations. However, the use of these plants in recent decades has put a lot of pressure on these resources, and many species suffer […]
The experiment was conducted to assess the effects of fertilizer types, and harvesting date on plant growth characteristics, dry matter (DM) yield and nutritional qualities of Mulato II grass. Data on plant growth characteristics, DM yield, and nutritional qualities of the grass were measured. The findings elucidated that fertilizer had a significant effect on the […]
This study was aimed to study the effects of cutting interval on yield, morphological and quality traits of three grass species under irrigation conditions in Mecha district, Ethiopia. There were three kinds of grasses namely Para (Brachiaria mutica Stapf.), Napier (Pennisetum purpureum), and Desho (Pennisetum pedicellatum) at three cutting days (60, 90,120). The experimental design […]
Climate change is one of the most serious threats to rangeland. The implications of climate change on the rangelands conditions of the Duda and Gomole in Southern Ethiopia were examined. Measurements of rangeland were made using field survey and focus group discussions. Descriptive statistics, one way ANOVA was employed to detect whether significant difference exists […]
Optimal habitat has a beneficial effect on species survival. In this research a logistic regression statistical method was used to prepare the potential distribution map of Artemisia aucheri Boiss. in 2020-2021. The maps of 19 bioclimatic and three physiographic variables with a resolution of 4.9 km under the current conditions prepared. Then, sampling information related […]
In temporal and spatial patterns, the critical (ecological) thresholds have rapid changes in ecological gradient. Determination of thresholds along the environmental gradients can help to control destructive factors and therefore, the success in restoration projects can be guaranteed. This study was conducted to evaluate the trend of changes in functional and structural indices along soil […]
Vegetation cover over time and space is the result of interactions between vegetation cover and environmental factors. Changes occurred in range covers are caused by matrix dominance, one of the most important environmental factors. Decision support system (DSS) could be used for determining the rate and importance of each factor. Actually, in methods based on […]
Floristic studies are fundamental for the applied sciences such as rangeland management and conservation. Unique ecological and climatic conditions in the Northern Khorasan Province (NKP) make it a remarkable habitat for the floristic studies. Plant species were collected from 50 field sites, representing major habitats of winter and rural rangelands. Surveys were conducted during active […]
In this paper, two formulas were chosen among those that estimate the suspended sediment discharge in rivers. These two formulas were Lane and Kalinske and Bagnold. For studying and knowing the correlation between input parameters and calculated suspended sediment discharge (CSSD), the SPSS17 software was used. Input parameters in these two formulas were as: water […]
