All gibbon species are targeted by the international wildlife trade. Today, on International Gibbon Day, we present some recent Mongabay stories about these agile, long-limbed apes. Signs of hope The endangered Javan gibbons (Hylobates moloch), found only on the Indonesian island of Java, are mostly confined to small forest patches today. Two such groups have become isolated from a larger forest area by farms and settlements in Central Java province. A local NGO, SwaraOwa, is working with farmers in the region to cultivate native trees and plant them to build forest corridors, Mongabay reported in a video published in June. The gibbon population there has increased from about 800 individuals 10 years ago to 1,000 in 2023. “Our motivation as young people is that future generations will not just hear stories about the gibbons, they’ll be able to see them from their backyards if they…This article was originally published on Mongabay
