Purna WLS lies at the border of Gujarat and Maharashtra, the northernmost portion of Biome-10 – The Western Ghats. The Forest of Purna consisted of moist deciduous forest with dense thickets of Bambusa arudinacea (Retz.) Willd. It has a flowering cycle of 45-60 years. In Purna WLS flowering occurred in 2007 after which they were harvested. A study was carried out to understand impact of bamboo harvesting, whether positive or negative on Avifaunal diversity of the WLS.


Point transects and trails were carried out. 18 point counts were walked during the period of December to April and extensive bird watching was done from June 2012 to May 2013. Results obtained were compared with the past data and the change in type of species obtained was noted and with use of habitat preference the impact of bamboo harvesting was tried to analyse. Species Discovery Curve reached asymptote on 6th transect indicating sufficient sampling effort.


139 species belonging to 56 families were observed. Two new bird records and one range extension was noted during current study. Out of the total 139 species 27 species recorded during present study were not recorded in the past whereas 21 out of 139 species recorded in past were not recorded during present study. Presence of the species preferring an open habitat and absence of species preferring a mixed habitat was observed.


Absence of species inhabiting dense habitat and presence of species preferring open and semi-arid habitat clearly indicates a negative impact of bamboo harvesting. Protection of the new bamboo seedling from being grazed is of utmost importance. Moreover the distribution is patchy and most of the species avoided human habitation due to extensive poaching going on in the sanctuary. A local awareness program needs to be conducted in the sanctuary.
