- Loss and fragmentation of Atlantic Forest
- Small, isolated populations
Why it matters
The golden lion tamarin is one of the best-known conservation success stories, showing how zoos, reintroduction, and forest restoration can rebuild a species — yet it remains dependent on protecting the highly fragmented Atlantic Forest.
A long-running reintroduction programme in Brazil's Atlantic Forest is often cited as a conservation success story.
