The brown bear has the widest worldwide distribution of all species of bears. Until recently it was found in North America, northern Mexico, Europe, Asia, the Middle East and North Africa. Today however, bears are only found in northwestern North America, Europe and most of North Asia. In Greece there are an estimated 450 bears living in two independent populations, which are not geographically linked. The largest population lives in the Pindos Mountains, and the other in the Rhodope Mountains. In recent years there has been consistent evidence of the presence of bears in the mountain axis of Vora-Olympos and Central Greece, even down to the mountainous Nafpaktia, an area where there have been no sightings in the last 70 years.
