Plants associated with
orchids (phorophytes) were separately recorded and percentage
of phorophytes in each study plot was calculated.
A binocular was primarily used to identify canopy
orchids, but we occasionally had to climb the trees to
identify small orchids. The number of individuals was
counted for species in which these were clearly demarcated,
whereas the species that showed clumped branchingbranching
pattern such as Bulbophyllum spp., Trias stocksii and
Pholidota imbricata were counted based on the total discontinuity
of the clump.
