Implement legal protection for primate species under threat
A study in 1991-2007 in tropical forests in Karbi Anglong district, Assam, northeast India found that the hoolock gibbon Hoolock hoolock population decreased by 33% over 16 years, despite being officially protected in India. Overall, the population declined from 3,500-4800 gibbons in 1991-1992 to 2,400-3,200 gibbons in 2007 (33% decrease). However, no statistical tests were carried out to determine whether this decrease was significant. The species is protected under Schedule-1 of the Wild Life (Protection) Act of India, which prohibits its killing or capture, dead or alive. However, the enforcement of this act appeared virtually non-existent, even in protected areas. Data on gibbon distribution and approximate population sizes were collected through field surveys along trails, roads and rivers and interviews of local forest staff, villagers and hunters.
