The provincial forestry protection department has implemented various projects funded by the FFI to improve the local people's living conditions, thus helping to remove their incentives for destroying the living environment of the animal.

These projects set up patrol teams to control and protect the forests in Ngoc Khe and Phong Nam communes, where 37 black langurs are living, according to a recent FFI survey.

The eastern black langurs are reported to live only in the northeastern region of Vietnam, Hainan island and the southeastern region of China. They have become rare since the 1950s and are now believed to be on the brink of extinction in Vietnam.
