Abstract
Abstract: The future of mammalian diversity in the tropics depends largely on the conservation value of human‐dominated lands. We investigated the distribution of non‐flying mammals in five habitats of southern Costa Rica: relatively extensive forest (227 ha), coffee plantation, pasture, coffee with adjacent forest remnant ([Panthera onca]),herbivorous (e.g., Baird's tapir, [Tapirus bairdii]),and arboreal (e.g., mantled howler monkey[Alouatta palliata])species. Although there is no substitute for native forest habitat, the majority of native, nonflying mammal species use countryside habitats. The populations of many persist even >5 km from relatively extensive forest, at least over the 40 years since forest clearance. Moreover, if hunting ceased, we expect that at least one of the locally extinct species could be reestablished in the existing landscape. Thus, there is an important opportunity to maintain and restore the diversity, abundance, and ecosystem roles of mammals in at least some human‐dominated regions of the Neotropics.
