| Popis: | To investigate the effect of surrounding tree density and the topography of the site of the host tree on the abundance, species richness, and diversity of epiphytic orchids, 32 trees of Schima wallichii were chosen randomly and the epiphytic orchids were counted and identified. Within a circle of radius 20m from each host tree, trees with diameter at breast height (DBH) greater than 20 cm had their species name and DBH recorded. In addition, the angle and direction of slope on which the host tree stood were measured. DBH of host trees affected epiphytic orchid abundance, species richness, and diversity positively. Density of trees surrounding each host tree, steepness and being on a north facing slope had a negative effect on epiphytic orchid abundance. However, species richness and the diversity of epiphytic orchids were not affected by any of the host conditions. |
