چکیده
To investigate the effect of surrounding tree density and topography site host on abundance, species richness, diversity epiphytic orchids, 32 trees Schima wallichii were chosen randomly orchids counted identified. Within a circle radius 20m from each tree, with diameter at breast height (DBH) greater than 20 cm had their name DBH recorded. In addition, angle direction slope which stood measured. affected orchid positively. Density steepness being north facing negative abundance. However, richness not by any conditions. • We studied community. basal area focal effects Host steep slopes or north-facing lower The more dependent tree.
