Wild golden lion tamarins live only in Brazil's Atlantic Coastal Forest. When deforestation brought the red-furred species close to extinction, scientists had to take action. But tamarins in zoos weren't breeding. How could scientists get that to change? Then, how could they get tamarins that were born in captivity to survive when introduced to a wild habitat? And once the population was growing, how could scientists connect the limited patches of protected forest to create a habitat large enough to support a healthy population? Find out how ingenuity and a "bridge" of trees made this a scientific success story.
