Sanje Mangabeys spend around 50% of
their time on the forest floor of the
valley forests they occupy. This
ground-dwelling behavior makes them
extremely susceptible to hunting and
getting caught in poachers' snares.

According to the IUCN-SSC Primate
Specialist Group, the Udzungwas are
considered the most important site in
Africa for the conservation of primate
diversity as this area is home to eleven
species of primates, including the Sanje
Mangabey.
