Position Statement of the IUCN Caprinae Specialist Group on Introduced Populations of Caprinae


Several wild species of Caprinae have been introduced in areas where the local biota has evolved in their absence. Because the introduction of exotic species can have many undesirable ecological consequences, it is appropriate for the Caprinae Specialist Group of the IUCN-SSC to express its opinion on this matter. This Position Statement provides a general guideline on the management of Caprinae as exotics. It is not a management prescription for any particular situation.



1. New introductions of Caprinae as exotics must be avoided, except those specifically aimed at conservation, such as establishing a 'rescue' population in the face of disease or other threat.

2. Established exotic populations must not be allowed to expand their geographic range.

3. When they have a negative impact on native biodiversity that would be reversed by their removal, the exotic Caprinae should be removed if feasible. Impacts may include introduction of parasites and diseases, competition or hybridization with native species or subspecies, impact on vegetation or on native predator populations.

4. When removal is either impossible or unnecessary, control measures to keep population density low should be put in place, especially if those activities generate funds for the protection of native biodiversity.

5. Research efforts on the impacts of exotic Caprinae on native biodiversity are a key priority to better manage these exotic populations.
