Siamang Welfare in Sumatran and Malaysian Forests

Siamangs are the largest gibbons, living in monogamous pairs in dipterocarp forests that are rapidly being converted to palm oil plantations.

Key Facts

Siamangs are classified as Endangered
They form lifelong monogamous pairs and both parents raise offspring
Their loud resonating calls using throat sacs carry up to 3 kilometres
Palm oil expansion has destroyed more than half of their Sumatran habitat
They travel through the forest canopy and cannot cross large open areas

Welfare Considerations

Habitat loss isolates pairs in forest fragments below minimum territory size. Infants orphaned in capture or hunting require 7-10 years of care before independence. Pairs separated by forest clearing show distress vocalizations for extended periods. Road and infrastructure development creates impassable barriers for these arboreal primates. Captive siamangs denied pair bonding suffer prolonged psychological distress.

What You Can Do

Support Sumatran forest protection programs
Choose certified sustainable palm oil to reduce habitat destruction
Donate to gibbon rescue and rehabilitation programs
Advocate for Sumatran rainforest moratorium on conversion
Engage with palm oil buyers on supplier deforestation commitments
