“…Rangelands play a crucial role in Türkiye's ecosystem and economy. 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).…”

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.

Forecasting the distribution patterns of invasive weed species under changing climate conditions is critical for the early identification of especially vulnerable regions and the implementation of effective preventive measures. In this study, the current and potential range of stranglewort (Cynanchum acutum L.)—an invasive alien species (IAS) in certain regions—are predicted under various climate scenarios, using the maximum entropy algorithm. Species occurrence data representing the natural distribution of C. acutum and 15 of the WorldClim bioclimatic variables are used. With an ensemble method, the impact of climate change on the distribution of the species is predicted according to five CMIP6 climate change models and three scenarios (optimistic: SSP245; middle of the road: SSP370; and pessimistic: SSP585). According to the findings, it is predicted in all scenarios that C. acutum could expand its range to the north, particularly in agricultural landscapes. Therefore, the invasive status of this species will likely continue in the future. This emphasizes the need to determine the priority of conservation targets, especially for agricultural areas, to ensure food safety and protect biodiversity.

The research was conducted in the pasture of Alpagut village of Kastamonu center (410 25' 48.52''N, 330 55' 20.54D, altitude 851 m) located in the Western Black Sea Region of Turkey to determine the changes in pasture vegetation caused by pasture soil improvement and management practices. Fertilization was applied according to pasture soil analysis, brush clearing and alternate grazing system was applied. Pasture vegetation change was measured by modified wheeled loop method in the pre- and post-improvement periods. It was determined that breeding practices increased the proportion of legumes, other families and perennial plants and contributed to the formation of a balanced vegetation. The proportions of declining, reproductive, invasive and annual species were 11.50%, 5.10%, 46.75% and 33%, respectively, before pasture topsoil reclamation, while there was a decrease in annual species in the post-reclamation period. There was an increase in declining, reproductive and invasive species. It was found to be 26.66%, 15.39%, 55.86% and 17.00%, respectively. While Bromus sp., Sanguisorba minor, Fumana arabica, Festuca ovina species were dominant in the pasture area in the pre-improvement period, Bothriochloa ischaemum, Teucrium chamaedrys, Festuca ovina and Astragalus frickii species became dominant after the improvement. It was determined that breeding and management practices increased the area covered with vegetation from 74.00% to 98.00%, the proportion of legumes from 1% to 12%, and the pasture condition and health classification from poor-healthy to moderate-healthy category. It is recommended that the grazing plan for pasture sustainability be maintained.
