An Iberian wolf has been released back into the wild in northern Portugal after being found caught in a hunters trap.
The animal spent two months being treated at the University of Trás-os-Montes and Alto Douro (UTAD).
According to Lusa News Agency, this is the first time the Institute of Nature and Forestry Conservation (ICNF) has released an Iberian wolf back into the wild after it was found injured, then rehabilitated.
ICNF spokesman said" This is a unique case in Portugal" as no other member of this species has ever been released back into the wild.
The wolf arrived at the University's recovery centre in a very weak state, having been found with a paw stuck in a hunters trap near the village of Meixedo in Montalegre.
Veterinarians were forced to amputate the injured leg, so the animal's chances of being released back into the wild were not high.
After two months of treatment however, the wound healed very well and the wolf had recovered better than expected, gaining weight and strength, which led to the decision last month that it would be able to survive in its natural habitat.
The wolf was returned to where he was found with a GPS device attached to him researchers can track his activities, survival and re-integration into his pack.
It is thought the wolf is currently around one year old and weighs 31 kilogrammes.
The wolf population north of the Douro River in Portugal is believed to be around 300 individuals.
