Ecology 141 for total abundance and another for species richness, to determine if there were differences between different categories of diameter and different elevational zones within trees.Results showed greater abundance and richness of orchids in the canopy of the medium-sized trees.Thus, estimates of plant diversity in cloud forests including the canopy are important.With regard to size of trees, it could be argued that the three diameter categories are associated with different temporal stages in the population dynamics of these orchids.
