over 2,000 km² and creating thousands of islands of between 1 to 1,000 hectares in size where land once was. As one could expect, this caused heavy degradation to the surrounding forest, leaving the remaining forest fragmented. As for many other species in the Amazon, the Ka'apor capuchin has also been a victim of hunting and poaching. One major concern for conservation of the species is the fact that so little standardized research has been done on the topic thus, in order to be able to protect them adequately we need to understand them more thoroughly.
