Comments and Curiosities

Conservation assessment: In the NT, this species is classified as Endangered; Fire and feral animals have been the primary threats impinging on the populations in the 1990s (Liddle et al. 1992ab, 1996, 2001, 2006). There was substantial mortality following wildfires at the Whitewood Road population in 1990 and 1993, and at Black Creek in 1992.

In a 1990 survey, Whitewood Road contained 42% of the known adults, however this was reduced to 5% by 2000-2001. Re-survey of Bankers Jungle in 2003 showed significant impacts from grazing with the loss of juvenile and adult plants.

Disturbance from feral buffalo, cattle and pigs declined in the 1990s following on from the Brucellosis and Tuberculosis Eradication Campaign, and changes in land use and fencing of four of the eight populations. In the early 1990s, Henry Any questions or if buying, contact me HERE
