In terms of biodiversity 95 of the vertebrate species are globally threatened with extinction according to the IUCN
Red List of 2009 (13 Critical, 40 Endangered and 42 Vulnerable). All but a couple of these species are Eastern
Arc endemic or near-endemic species. Further details on the red list species can be found on www.redlist.org.
Population trends are only known for monkey populations in the Udzungwa Mountains National Park. The Sanje
Mangabey has a population of 2,800-3,500 individuals; the Iringa red colobus has a population of 25,000-35,000
individuals, and the Kipunji monkey has a population of around 100 animals (with a further 1,100 in southern Mbeya)
(Rovero et al., 2009). Monitoring and studying the primates in this park is planned to continue indefinitely.
A summary of the attributes that have been monitored in the Eastern Arc and are hoped to be monitored into the
future are outlined below.
