Discussion session: Prospects and challenges

Abstract

This paper focuses on mammalian pest species mainly in Europe and Africa and on implications for animal health, human safety, wildlife management and animal welfare. Three examples of problem species are presented: the wild boar (Sus scrofa), the stray dog (Canis familiaris) and the red fox (Vulpes vulpes). Several species are reservoirs or vectors of transmissible diseases of man and of economically valuable domestic species. The control of these and other infections and the limitation of the nuisance or damage caused by these pest species involves lethal or non-lethal methods which are briefly reviewed. Some control measures require veterinary expertise, and veterinary involvement in managing problem species is likely to increase. With regard to fertility control, methods are considered which will allow an appropriate choice of the best technique for the management of problem animals in various habitats. For desirable native species, traditional methods of control, especially hunting in the case of game species, is preferable to contraception. For exotic or feral species, control of fertility seems to be a worthwhile option.
