Mountain mist frog
Scientists think pigs that escaped from humans might be one reason why the frog is endangered.  The pigs rip up the streams where the frog would live.  They also think the fungal disease chytridiomycosis might be killing these frogs.  Scientists also thought habitat loss, human beings building roads and farms where the frog would live, was killing the frogs, but the Australian government protected the frogs' home in 1988.
