Learn about the Western Hoolock Gibbon

The Western hoolock gibbon (Hoolock hoolock) is a Critically Endangered species in Bangladesh and Endangered globally. The gibbon habitats of Bangladesh are rapidly being destroyed due to habitat fragmentation and degradation, illegal encroachments and expansion of agricultural land. Presumably, gibbon populations of Bangladesh will not survive without concerted long-term conservation intervention. Already, some gibbon populations have become locally extirpated from many habitats. The last population census was conducted more than one decade ago with an estimated ca. 250 mature individuals to occur in Bangladesh. Since then, gibbon populations have vanished from more than five sites in Bangladesh as their habitat characteristics have drastically changed; however, we are hopeful to identify currently unknown gibbon habitats in Bangladesh with a new census.
