Species diversity in relation to physiographic factors in Lashgerdar protected region, Malayer, Iran
Abstract
Rangeland is a natural ecosystem including large sources of genetic resources and diverse plant species which always guarantees the rangeland stability against environmental and biological factors. Objective of the present study is to investigate relationship of species diversity and richness to topographic factors. In this regard, the study was conducted in Lashgerdar protected region in Malayer city located in Hamedan province. After determination of work unit with specific characteristics of slope, direction and elevation, the sampling was conducted as random-systematic. Coverage measurement was carried out by establishment of four perpendicular transects with a length of 100 m in each of them. Then, ten 2 m2 plots were established along each transect, and then, diversity, species richness and uniformity were determined in each plot after determination of plant cover. Correlation analysis and multi-variable regression were used in SPSS software to determine relationship of diversity, species richness and uniformity to topography. The results showed that, there is a relationship with confidence level of 99% between topographic factors and species diversity and richness. No relationship was seen between uniformity and topographic factors. Diversity was reduced between the elevations 2000 to 2600 and the elevation class of 2000-2200 had the maximum diversity and richness. Among the studied directions, the southern slope had the maximum species diversity and richness.
