The Gibbon Network serves to connect people interested in gibbon conservation and research. It offers a list of field sites in South-east Asia specializing in gibbon research and reintroduction, a survey of the zoo gibbon population, information on gibbon studbooks, a list of ongoing or recently completed gibbon-related projects, a list of the most recent publications and theses on gibbons, and gibbon fact sheets.
Both pages are updated frequently and also jointly offer a Gibbon News page presenting the latest information on gibbon biology and conservation.
