The Hainan gibbon continues to survive in Bawanglin Nature Reserve in four social groups totalling 21 individuals. Twelve births have occurred since 1982, and 11 of these individuals survive in 1989. Only three of these 12 births have been females, however. The total female population consists of 6 adult females, two of which are at least 19 years old, and three juvenile females born since 1985. Two of the four social groups have only one adult female each and no juvenile females. All four groups are well protected, but their survival is precarious.
