Answer:
There are two species of hairy-nosed wombat: the Northern Hairy-nosed wombat and the Southern Hairy-nosed wombat. The Southern Hairy-nosed wombat is not endangered, but is listed as secure.
The northern hairy-nosed wombat became endangered through a combination of competition for food with introduced European cattle, sheep and rabbits, and the habitat alteration that resulted from these European farming practices.
Apart from the intrusion of people into their environment, this species of wombat is endangered due to drought, which has decimated the wombat's food supply, predation by dingoes, human interference and hunting, habitat loss, and competition from introduced cattle, sheep and rabbits for food and shelter. The greatest current threat is that there is only one known population in existence.
