[update]

hm, the article says the opposite about the common wombat.

> Now, despite its name, the common wombat is no longer common. Overgrazing and the destruction of their natural habitat has caused a sharp drop in their numbers; all species of wombat are now protected, and the northern hairy-nosed wombat is critically endangered.
