was still within the range of actual and potential carbon values under the various markets (Hamilton et al. 2009). Protecting the forests of Kalimantan through such payments would protect the habitat of a large number of threatened animal species, including the Bornean orangutan (Venter et al. 2009), indicating that there is a clear regional potential for carbon payments to become an important element in biodiversity conservation.
Opportunities for great apes in general All great ape species predominantly live in tropical rainforests (Caldecott and Miles 2009), which are among the most carbon- rich areas in the world (Map 27). Tis overlap between the areas where great apes occur and carbon indicates that more potential synergies between great apes and carbon conservation exist. Fu- ture studies should examine this potential synergy for the great apes of Africa.
