Individual Iberian Lynx may still survive in the wild in Portugal, either as remnants of past populations, or crossing over from known wild populations in southern Spain. However, the long term recovery of the species in Portugal will likely require captive breeding and reintroductions, along with habitat conservation, reductions in predator persecution and the recovery of wild rabbit populations.
Lynx bred and raised in captivity in Portugal will form part of the unified management of the Iberian Lynx captive breeding programme, across the Iberian Peninsula. Lynx in Silves could thus be reintroduced in either Spain or Portugal, depending upon progress made with preparing adequate reintroduction areas in each country. This, in turn, will require identifying and preparing areas with adequate prey and habitat, and a supportive local human population.
