Biodiversty indexes and factors affecting them in some micro watersheds Çoruh watershed

In this study, we aimed to investigate biodiversity indices and the factors affecting biodiversity in some of the micro-watershed in Coruh River Basin. The study area consists of 8 micro-catchments. In the study area, number of species, the number of individuals and average degree of coverage measurements were made. Transects bars were used for these measurements. For study purposes; we investigated that effects of precipitation, temperature and slope on the number of individuals, average cover and number of species. The findings are calculated with Biodiversity index, Simpson index, and Shannon Weaver index. As a result of study, it has been determined that the average cover increases as increase with altitude rainfall the number of individuals species but the average cover decreases as increase with temperature and slope. Then it has been found that the number of species increases as increas with altitude and rainfall, but the number of species decreases as increase with temperature. Besides, it has been found that the number of individuals increases as increase with altitude and rainfall but the number of individuals decreases as increase with temperature
