Conservation issues and strategies for elephant-shrews

Abstract

The recommendations and implementation of the IUCN conservation plan for African Insectivora and elephant-shrews (Nicoll & Rathbun, 1990) are reviewed. Of the 33 species and subspecies of elephant-shrews, only six forest-dwelling taxa are threatened. Until additional status data are gathered, assessed, and published no changes in the IUCN threatened categories should be made: Rhynchocyon chrysopygus is ‘vulnerable’; Rhynchocyon petersi petersi and Rhynchocyon petersi adersi are ‘rare’; and Rhynchocyon cirnei cirnei, Rhynchocyon cirnei hendersoni , and Petrodromus tetradactylus sangi are ‘insufficiently known’. Implementing status surveys that have not been completed, especially for the forms of R. petersi and P. t. sangi , are a high priority. Rhynchocyon petersi and R. chrysopygus densities are lower in altered and trapped forests compared with undisturbed forests. Because undisturbed forests in eastern Africa are highly fragmented, small, and disappearing due to human encroachment, it is important to determine the population dynamics of Rhynchocyon spp. that occupy degraded forest habitats, such as plantations, follow agricultural lands, and coastal scrub. In the face of the expanding human population, with its increasing need for land and natural resources, Rhynchocyon populations that occur in these degraded habitats may be all that remain in the future.
