In the early twentieth century, the Iberian wolf, Canis lupus signatus, occupied almost the entire Iberian Peninsula. However, over the last hundred years the area of distribution has been severely reduced.
In Portugal, the gradual disappearance of the wolf, particularly along the coastal strip, became increasingly more evident from the 1940s. Since the drastic reduction of the wolf’s habitat in the 1970s, the situation has become much worse.
The wolf population is not distributed continuously throughout its range, on the contrary, it is very fragmented, with many areas where wolves are disappearing or have been exterminated.
