Declining in number because humans are taking their coastline forest away
The Golden Lion Tamarin is a monkey that lives in the forest along the coastline of Southeastern Brazil. Thriving towns emerged along the coastline because humans also found it to be easier to live in these areas. Humans have cut down about 90% of the forest where the Golden Lion Tamarin used to live. Another problem is that people are drawn to the beautiful golden fur of the Golden Lion Tamarin and have been capturing them as pets, reducing their numbers to a point where extinction has become a real concern.

Grow more forests for the Golden Lion Tamarin!
Experts were quick to realize the reputation of the Golden Lion Tamarin as a beautiful animal would make it an endangered species. From the 1970's, zoos started breeding Golden Lion Tamarins to increase their numbers, and about ten years later, began releasing the new bred monkeys to their natural habitats. These efforts have certainly increased their numbers, but the results are limited because the forest still occupies only a small area. This is being addressed by planting more trees, and taking action to expand the forest.
