The 'Northern Hairy-nosed Wombat' (''Lasiorhinus krefftii''), also known as the 'Yaminon', is one of three species of
wombats. It was found across New South Wales, Victoria and Queensland as recently as 100 years ago, but is now restricted to a 3
km² range within the 32 km²
Epping Forest National Park in Queensland. It is probably the rarest large mammal in the world and is
critically endangered. It is slightly larger than the
Common Wombat and able to breed somewhat faster (two young every three years). Its habitat has become infested with
African
buffel grass, which out-competes the native grasses the Yaminon prefers to feed on. A two
metre-high predator-proof fence was constructed around 25 km² of the park in 2000, but captive breeding and translocation programs have been abandoned for the time being because the population in the sole remaining Yaminon colony is considered too small to allow the safe removal of the 15 or 20 individuals needed to start a new wild colony, and because more than a decade of captive breeding research with Common and
Southern Hairy-nosed Wombats has produced only a handful of successful births.
The Northern Hairy-nosed Wombat is listed as "endangered" by the Australian Species Profile and Threats Database (SPRAT),
[ ''Lasiorhinus krefftii'' Northern Hairy-nosed Wombat ] and "
critically endangered" by the
IUCN.
