Anstisia vitellina

It is vulnerable to extinction due to fire and the destruction of habitat caused by feral pigs.

The species occupies an area of 20 ha, the smallest of any Australian mainland vertebrate, across a range of 6.3 km2 around Witchcliffe.

Six creeks on the Blackwood River, Western Australia have been found to provide appropriate habitat.

Populations are isolated due to breeding behaviour and a small individual range—unusual for frog species.

The small range of this species has made it vulnerable to threats such as fire and 'wild pigs', water solutionism through agricultural runoff, and changes to the hydrology of the riparian habitat through land-use.
