Drought stress is one of the most important factors limiting the survival, growth and production of various crops and medicinal plants in the different habitats of Iran. This study was conducted to evaluate the effects of drought stress on seedling growth and physiological traits in four native thyme species as (Thymus kotschyanus, T. dianensis, T. […]
This study was performed to evaluate the forage nutritive value of Cymbopogon olivieri before and after conducting the essential oil extraction in rangelands of Khuzestan province, Iran. In this study, the aerial parts of Cymbopogon olivieri were collected in flowering stage from 10 natural regions located in Khuzestan province in 2016. Regions included ChalGandali, TalkhabKalat, […]
This study was conducted on the south slope of Al-Jabal Al-Akhdar (the Green Mountain) rangelands, northeast Libya to investigate changes in perennial plant species richness, landscape function and soil surface condition in order to determine whether exclosures are effected strategy for the improvement and rehabilitation of rangeland ecosystem at the regional level. Four study sites […]
Most of rangeland soils are limited in their ability to supply adequate nutrients to plants. Soil conditioners have been shown to alter soil fertility and plant characteristics. This investigation aimed to evaluate the influence of two soil conditioner on nutrition value of N. schoberi and A. podolobus. For this, two separate experiments for each species […]
Trend of vegetation in typology scale has remained uncertain especially in arid ecosystems. Therefore, we aimed to asses two vegetation indices including as the Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI). Trends and their rates of indices in vegetation types were analyzed by the Mann–Kendall test and Theil–Sen trend estimator. To this […]
The information about the forage quality of rangeland species is essential to supply a reasonable diet to livestock and determine thestocking rate and grazing time on rangelands. Salsola turcomanica is one of the important species of semi-arid rangelands in the Western part of Golestan province, Iran. The present study was conducted to provide information about […]
Rosa persica Michx. ex Juss. is an aggressive plant species in Iranian rangelands. Several controlling methods have been suggested to stop its expansion. This study examined the short-term effects of fire, tilling, cutting, and herbicides as a means of controlling Rose persica on the richness, evenness and diversity of R. persica communities in rangelands of […]
Studying the phenology of valuable native plants which are on the verge of extinction, is very important and effective for better introduction and protection of them. Fritillaria raddeana is one of the native bulbous plants with ornamental and medicinal value in Iran. The aim of this study is to investigate the phenological stages of F. […]
Forest grazing of cattle, horse and sheep is allowed under certain strict regulations. Black locust forests have major importance amongst domestic forestry (Central Europe), as their habitat are situated on less productive sand soils. In most cases there are no other option than setting trees next to the grazing areas. Black Locust (Robinia pseudoacacia) leaves […]
