This is a big relief for reserve forests coming in Siruvanjur (Chengalpattu range) in Kancheepuram, Manjavadi Ghat and Pallipatti in Shervaroyan Hills, and Jarugumalai in Salem and Tiruvannamalai districts. Under the project more than 10 lakh trees should have faced the axe and this express corridor if executed will reduce the wildlife habitats endangering spotted deer, sloth bear, peacock, snakes, jackal and hare, the wildlife biologist added.
