The aim of this research was to study the relationships between presence of plant species and environmental factors in Garizat rangelands of Yazd province and providing their predictive habitat models. After delimitation of the study area, sampling was performed using randomized-systematic method. Accordingly, vegetation data including presence and cover percentage were determined in each quadr...

carbon sequestration in rangeland ecosystems has been identified as a suitable strategy to offset greenhouse gas emissions that information of carbon sequestration hotspots is a good tool to improve rangeland management. objectives for this study were to assessment potential carbon sequestration in various rangeland types, to identify carbon sequestration hotspots and to study the effective fact...

Abstract This paper presents a quantitative account of vegetation–environmental factor relationships in arid rangelands. Vegetation cover was recorded using Braun-Blanquet combined abundance-cover scale in each quadrat. Within each quadrat, one profile was dug and soil samples being taken at 0-20cm and 20-100cm depths. Under study physical-chemical characteristics included texture, lime, orga...

Due to drought, low soil fertility, little rain fall, elevated levels of evapotranspiration, salinization the and a lack ground water, problem desertion agricultural areas has developed in KSA recent years (e.g. Tabuk region). In Saudi Arabia, land abandonment’s negative impact on composition perennial vegetation, quality, structure population was investigated. several abandoned fields research...

Lead (Pb) soil contamination remains a major ecological challenge. Zygophyllum fabago is candidate for the Pb phytostabilisation of mining tailings; nevertheless, cytogenotoxic effects low doses on this species are still unknown. Therefore, Z. seeds collected from non-mining (NM) and (M) areas were exposed to 0, 5 20 µM four weeks, after which seedling growth, redox status analyzed. The data re...
