Observations on the habitat distribution of orchids of arunachal pradesh india



Journal of the Bombay Natural History Society 82(1): 114-129



ISSN/ISBN: 0006-6982

Observations on the habitat distribution of 208 species of Orchids of Arunachal Pradesh have yielded interesting data. Based on the variations in altitude, temperature, rainfall and humidity along with the type of vegetation, four orchid zones have been recognised which seems to determine primarily, the habitat of both terrestrial and epiphytic orchids. Other factors like light and shade, phorophyte type and quality, soil pH, type and organic content also seem to be responsible for determining the habitat and distribution of individual species. Details are given under each zone and a list of species occurring in each of them is given in a tabular form indicating the area of distribution of the individual species. Competition among and between the orchid species and other associate plants appears to be an important factor responsible for migration. Based on these observations and floristic analysis it appears that the species of orchids from a particular region tend to migrate to the neighbouring regions with favourable habitat conditions in a radiating pattern and the rate of distribution is inversely proportionate to the distance of their migration.
