  • One site comparison in Laos found that Laotian black crested gibbons occurred at higher densities in areas where they were protected by a local hunting taboo than at sites were there was no taboo.

Supporting evidence from individual studies


A site comparison in 2007 in tropical forest in Nam Kan Valley in Nam Kan Provincial Protected Area, Laos found that Laotian black crested gibbons Nomascus concolor lu that were protected by a local hunting taboo occurred at higher group densities compared to other sites. In the survey area, average group density was estimated at 2.2 groups/km2 compared to 0.43 to 0.82 and 1.6 groups/km2 in Yunnan Province and Che Tao in northern Vietnam, respectively. However, no statistical tests were carried out to determine whether this difference was significant. The ban was implemented in 1975 by one of the local village heads. In Yunnan Province and Che Tao no hunting bans were reported to exist. An auditory survey was conducted in the survey area using eight single listening points stationed roughly 0.5-2 km apart, each of which were used on one to five days.
