“…Mismanagement practices have led to a significant loss of original vegetation in Turkish rangelands (Sürmen & Kara, 2022). Suitable range management changes are recommended to conserve natural resources in highland rangelands (Koç et al, 2020).. Rangelands, covering 22.9 million hectares in Türkiye, historically support livestock production through seasonal grazing (Yetişgin & Aydemir, 2019). These rangelands are vital for animal husbandry in the eastern Anatolia region due to the challenging topography and short growing season (Koç et al, 2021).…”

“…The relationship between slope and rangeland dynamics is a critical aspect of understanding the ecological and environmental processes in these ecosystems. Research by Koç et al (2020) highlights the impact of elevation, slope aspect, and the degree of slope on the vegetation structure, composition, and productivity of rangelands in the Palandöken Mountains, Erzurum, Türkiye. This study emphasizes the influence of topographic factors, including slope, on rangeland deterioration due to heavy grazing, providing valuable insights into the specific mechanisms driving rangeland changes in this region.…”

Rangelands, which have rich plant and animal biodiversity, are also very important as a source of roughage for livestock. Rangeland vegetation patterns vary considerably under the influence of environmental factors. Indicator factors need to be identified and analyzed in order to manage conservation and utilization objectives. In rangelands of the Aegean region, the slope factor can greatly affect the rangeland plant biodiversity in areas close to the base rangeland. In order to investigate the spatial distribution and species variation in plant biodiversity caused by slope, 6 rangeland sections with different slopes were sampled in Koçarlı region (Aydın / Türkiye). Sampling was carried out using the transect method in the spring 2017 based on field observations. Following sampling, indicator species and species distribution and abundance were determined. Alpha biodiversity indices were used to determine the change in species biodiversity by SHE analysis. SHE analysis tests the relationship between S (species richness), H (Shannon-Wiener diversity index) and E (equality). This method aims to examine the contribution of the number of species and the concept of equity in the context of diversity. According to the information obtained as a result of the analysis, it was seen that the increase in slope may cause a decrease in species biodiversity. More species diversity was found in rangelands with low base and slope. Factors such as erosion and water transport affect the canopy and species abundance in high slope rangelands. However, other factors such as grazing intensity can reverse this situation. For this purpose, it has been determined that slope is an important environmental variable when preparing management plans based on grazing capacity and grazing animal species in vegetation studies.

“…This can alter the natural composition of herbaceous vegetation by reducing the abundance of perennials [13]. Heavy grazing on perennial species can alter competitive interactions between palatable perennial species and lower-palatable annual species [22]. This causes a shift in vegetation and can result in the dominance of unpalatable and grazing-tolerant annual species [21].…”

Influence of Pastoral Settlements Gradient on Vegetation Dynamics and Nutritional Characteristics in Arid Rangelands

An expansion of pastoral settlements in arid rangelands can increase pressure on fragile ecosystems. High stocking rates and inappropriate rangeland management can cause large, difficult-to-reverse changes in the composition and structure of rangeland ecosystems. This study aims to understand changes in vegetation composition (cover, density, biomass, richness, diversity) and nutritional characteristics of range vegetation along a gradient of increasing pastoral population in arid rangelands of Pakistan. Three sites were selected for sampling within three areas classified by their distance from settlement: Near, Away, Far (9 sites in total) belt transects (10 × 150 m). A total of 90 transects (30 each in classified sites) of size 10 × 150 m were placed at a distance of 100 m apart from each distance group. Results identified 28 species from nine plant families. We found a significant difference in vegetation characteristics along the gradient. Vegetation diversity increased along the settlement gradient, highest being in the far sites. Density, plant cover and biomass were greatest at the sites near pastoral communities and decreased as the distance from the settlements increased. Palatable species were characterized by low density and diversity near herder’s villages, but values increased as the distance from the villages increased. An increase in shrubs was observed near pastoral settlements, resulting in higher plant cover, biomass and density in these sites. This study identified anthropogenic impacts on rangeland structure and composition and found large shifts near communities. The frequent monitoring of vegetation resources is important, and the development of sustainable conservative strategies are recommended to ensure harmonious coexistence of pastoral populations in arid rangelands.
