Poland has historically been home to rare species of animals, as well as the two largest European mammals: the wisent (''żubr'') and aurochs (''tur''). The last aurochs of Europe became extinct in 1627 in the Polish Jaktorów Forest, while the wisent survived until the 20th century only at Białowieża. It has been since reintroduced to other countries. Other wild species include the brown bear in Białowieża, in the Tatras, and in the Beskids; the gray wolf and the Eurasian lynx in various forests; the moose in northern Poland; and the beaver in Masuria, Pomerania, and Podlaskie.
