The golden-headed lion tamarin is perhaps one of the most beautiful of the marmosets and tamarins. Classified as Endangered, its population is decreasing and its habitat is severely fragmented. Tamarin Trust recently visited the area to see what we could do to help. For more information on what we found, click here.

The Tamarin Trust is now partnering in a new conservation initiative focused on this species in the Brazilian state of Bahia. This comes in response to an escalating crisis, as rapid agricultural, urban expansion and road development continue to fragment the tamarins’ natural habitat. Much of their forest habitat is being converted into cattle pasture or coffee plantations.

Recent video footage has highlighted the dire conditions faced by some tamarin family groups, now stranded in isolated forest fragments near urban areas. With reduced resources they need to move between forest fragments, so monkeys are found dangerously close to roads, at serious risk from traffic, electrocution on overhead powerlines, and attacks by domestic pets. There are currently no dedicated facilities equipped to properly rescue and rehabilitate lost tamarins.

Supported by Michele and Paul Masterton, we are building two initial rehab enclosures, complete with monitoring cameras. These enclosures will provide a safe space where tamarins can be assessed and cared for, and ultimately released back into secure forest habitats when ready.  Releases will occur after working closely with field workers who are monitoring the last remaining tamarins in the wild.

This rescue and rehabilitation project is just the beginning.  In 2026, the Tamarin Trust will co-host the next in its series of marmoset and tamarin conservation husbandry workshops, in the city of Ilhéus in the heart of the golden-headed lion tamarin’s range. Experts and conservationists will collaborate on expansion plans for a full-scale tamarin rescue and rehabilitation centre. The goal: to create a central hub where at-risk tamarins in the area can be brought for care, monitoring, and release.

This initiative will also integrate with ongoing fieldwork to monitor remaining tamarin populations in fragmented habitats, helping conservationists track movement, health, and population trends. Field researchers will be able to identify the areas the tamarins are most at risk on local roads, and with this information, Tamarin Trust plans to create canopy bridges to give tamarins safe passage over roads. This project marks a critical step toward safeguarding the future of one of the world’s most endangered primates.
