It resembles the more westerly distributed Acacia oxyclada. According to Maslin this species is probably better treated as an infraspecific taxon of A. oxyclada, but seeds should be examined before any change is made (Orchard and Wilson 2001).

General Information Distribution Acacia basedowii is endemic to Australia found in central Australia from Rawlinson Range and Skirmish Hill in east to Macdonnell Range in the Northern Territory and Musgrave Ranges in .

Threats There are no major threats known to this species. Reducing the effects of inappropriate fire regimes is a priority in the Great Sandy desert region.

Past Present Future 13 None  Conservation Measures It is known to occur within protected areas across its range. Most notably it is found in Lands and Watarru Indigenous Protected Areas, Uluru-Kata Tjuta and West MacDonnell National Parks. It is not listed as Threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). It is listed as Least Concern using IUCN ver. 3.1 under Schedule 2 in the Northern Territory (Northern Territory Government 2007). It is recommended that its seeds are banked as an ex situ conservation measure.

IUCN Red Listing Red List Assessment:(using 2001 IUCN system) Least Concern (LC)

Red List Criteria: Date Last Seen (only for EX, EW or Possibly EX species): Is the species Possibly Extinct?  Possibly Extinct Candidate?  Rationale for the Red List Assessment A. basedowii is a small shrub distributed in rocky hills in central Australia. There are no known threats to this species and it is known to occur within protected areas. The extent of occurrence of this species does not warrant a threatened category, therefore this species is listed as Least Concern. It is recommended that its seeds are stored as an ex situ conservation measure.
