the Fazenda Rio Claro and the Fazenda Tucano (which have roughly 3.66 and 1.0 individuals per square kilometer respectively). There have been several attempts to bring black lion tamarins into captivity and to salvage what little habitat they have left within the Morro do Diabo State Park, as well as to increase breeding rates. Their population decline in the wild, however, could cause the black lion tamarins to become entirely endemic to the Morro do Diabo.
