Barbara Brown's titi establish a Central Biodiversity Corridor that aims to connect fragmented forests, while WWF is developing an overall conservation strategy for Brazil’s Atlantic forests. Further research is needed into the ecology and status of this enigmatic species if it is to be pulled back from the brink of extinction. Barbara Brown's titi Barbara Brown's titi ("Callicebus barbarabrownae"), also popularly known as the blond titi monkey or northern Bahian blond titi, is a species of titi, a type of New World monkey. This critically endangered species is endemic to the Caatinga in northeastern Brazil, and it is estimated that less than 250
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
