White-eared titi prevent hunters on the land, thereby inadvertently protecting the species. It also appears that the titi monkey can cross open ground between forest fragments, and some groups can thrive in disturbed habitats near human activities. However, the fragmented habitats may prevent the establishment of new territories and decrease reproductive opportunities. Forest corridors to connect fragmented forests have been proposed as an effective means to help ensure the survival of the titi monkey. The white-eared titi is found in the Beni Biological Station Biosphere Reserve and the Amboro National Park in Bolivia and benefits from the protection these reserves provide. White-eared
Coimbra Filho's titi fragment of the population, limiting reproductive options. The species' natural geographical distribution also contributes a threat to the species. Coimbra Filho's titi only naturally occurs in the Atlantic coastal forests in northeastern Brazil. This is a relatively small area in the states of Sergipe and Bahia. Due to this small range, any disturbances to these areas pose a larger than normal threat to the species' survival. More than anything else, however, human interference is the source of many problems to Coimbra Filho's titi. The areas around and inside its habitat are being developed, including paving roads and the promotion of
