Forest, and Cordillera de Colán National Sanctuary. From the mid-1980s until recently, further conservation or research efforts were minimal. Starting in 2007, though, British NGO Neotropical Primate Conservation has been running conservation initiatives for the species throughout its range. The species is considered one of "The World's 25 Most Endangered Primates". Habitat loss by deforestation is the biggest threat to the endangerment of yellow-tailed woolly monkeys. The Lima-Tarapoto highway which runs through the regions of San Martin and Amazonas has caused the immigration of people from coastal and high mountain regions leading to overpopulation. Due to the negligence of the regional government of Shipasbamba, Amazonas to the accept requests for conservation efforts, local lands have been the victims of slash-and-burn agriculture by local farmers to support the growing demand of local agricultural crops, as well as to support the increase in population size. With the deforestation and increased population, the monkeys have had their habitat range reduced, which increases their risk of extinction. Conservation efforts led by ASPROCOT have been made recently to help protect the endangered monkeys by turning to alternative forms of agriculture to preserve the remnants of the Amazonas forests. However, a lack of funding has slowed the conservation process. Several communities in Peru have made conservation efforts to preserve the yellow-tailed woolly monkeys through various ways. Community-based conservation efforts have been made in preserving the monkeys, such as in Los Chilchos valley, where the project is directed by the Apenheul Primate Conservation Trust. Efforts include preventing further immigration into areas home to the monkeys and beginning ecosystem protection initiatives. Neotropical Primate Conservation has begun using newly constructed roads in La Esperanza to access areas which are now being used to develop ecotourism initiatives to build awareness about the endangered monkey population and its habitat, which has helped local people understand the importance in preserving the monkeys and that the monkeys can be used as a valuable tourist attraction.
