The Frankfurt Zoological Society, The Orangutan Project, and the World Wildlife Fund have been campaigning to obtain the management rights for two forestry concession blocks adjacent to the Bukit Tigapuluh National Park in Sumatra, Indonesia. Recently, the Indonesian Ministry of Environment and Forestry granted the licence for an Ecosystem Restoration Concession, an innovative way to preserve native forest areas from logging. With this new conservation concession 39,000 hectares have been made available to orangutans for at least 60 years. The area directly adjoins the 145,000 hectare Bukit Tigapuluh National Park.
