One of the biggest threats to the South of the Douro River wolf population is the scarceness of wild prey. Reintroducing wild ungulates not only increases the number of available prey, but also reduces impacts on livestock and consequently conflict with man.
Reintroduction of animal species is being used as a valuable tool for wild life conservation and management, as shown by the growing number of programs that include this method. Reintroductions are used to restore or reinforce extinct populations or in cases where population size is diminished.
The Roe deer is considered the most appropriate native prey species for reintroduction in this region. The aim of this project is to create in the long-term a stable roe deer population in the South of the Douro River region.
