Genetic resource banks in wildlife conservation

Recent advances in reproductive technologies for animal breeding, together with improvements in techniques for storage of gametes and embryos, have encouraged the view that the time is now appropriate for developing systematic policies of germplasm banking. Such activities would aim to support more conventional breeding programmes for threatened species, by providing the opportunity to store valuable genetic material for use on some future occasion. A number of pertinent issues should be addressed, however, before embarking upon the large scale implementation of genetic bank programmes. This review raises and discusses some of the issues involved.
