Abstract

Forest road construction is one of the effective factors for ecological changes affecting the DIVERSITY and species composition in roads edges. This research was performed in Kheirud forest to evaluate the herbaceous DIVERSITY and tree regeneration establishment in different distances from road edge. For this purpose, we sampled herbaceous and tree species regeneration in 0,5,10,25, 50 and 100 m distances from road in down and up-hill sides. BioDIVERSITY indices (Shannon and Simpson), RICHNESS index (species number) and EVENNESS index (Pielou) were calculated to determine the degree and magnitude of road effects on herbaceous and regeneration DIVERSITY. The results showed that the species DIVERSITY, RICHNESS and EVENNESS indices were not significantly related to down and up slopes while these attributes were significant to distance from the road. Distance from road edge was a significant factor which affects the composition and distribution of HERBACEOUS PLANTS and TREE REGENERATIONS. Based on the results, among the environmental factors carbon, nitrogen and pH were major determinants of species distribution and abundance of road to interior forest gradient. These results are expected to provide critical information for decision makers to design careful and appropriate FOREST ROADS to minimize damages of habitats for regeneration establishment and also help to select the proper species for bioengineering.
