The range of the black-handed tamarin is within one of the most densely inhabited areas of Brazil, where logging has removed a significant amount of the original forest, causing a decrease in food availability and refuges from predators.[1] However, black-handed tamarins are adaptable foragers that can make use of primary, secondary and logged forests, which increases the potential available range of habitat.[2] Populations are present in several reserves where logging is prohibited, including Gurupí Biological Reserve, Tapirapé Biological Reserve, and Caxiuanã National Forest.[3] In central-western Brazil, in the southern part of their range, most black-handed tamarins are only able to survive in the remains of forested areas on private properties.[3]
