Abstract:   (2991 Views)
The present study was performed to identify diversity indices of herb layer functional groups and its relation to physiographical factors in central Zagros forest, Lorestan. In so doing, sampling of herbaceous plants was conducted randomly in plots of 2×2 m (n=50) in site. All plants were classified to functional groups including forbs, graminoids and legumes, also Raunkiaer's life-forms. Diversity values (Richness, Shanon-weawer's diversity and Hill's evenness indices) were measured in each plot. Totally, 103 plant species were identified which belong to 27 families and 82 genera. Results indicated that aspect influenced the forbs as well diversity indices of graminoids and legumes. Rather, slope and altitude had no effect on diversity indices. In research site, aspect had important impact on plant distribution and diversity of plant functional groups. Generally, it can be stated that ecological and managemental factors including landuse changes and grazing intensity in Zagros region influenced the plant species composition.
