Conservation overview

The golden lion tamarin is a small, brilliantly orange monkey of Brazil's Atlantic Forest, named for its lion-like mane. It is assessed as Endangered.

It lives in family groups and was brought back from the brink by captive breeding and reintroduction.

Range & habitat

Remnant Atlantic Forest in the state of Rio de Janeiro, Brazil.

Major threats

Threats below are drawn from the authoritative sources listed on this page. For the current, complete assessment, see the IUCN Red List.

  • 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.

Frequently Asked Questions

Why is the golden lion tamarin famous in conservation?
It is a celebrated example of recovery: captive breeding in zoos, reintroduction to the wild, and forest protection helped rebuild the population from a very low point.
Why is it still Endangered?
Published assessments cite the loss and fragmentation of its Atlantic Forest home, which leaves small, isolated populations. See the IUCN Red List for the current assessment.
