|Scientific Name:||Acacia jacksonioides|
|Taxonomic Notes:||Similar to A. erinacea Benth. and A. semicircinalis Maiden & Blakely.|
|Red List Category & Criteria:||Near Threatened ver 3.1|
Acacia jacksonioides is a small shrub distributed in eucalypt woodland in the Avon Wheatbelt region in Western Australia. Its extent of occurrence does not meet the criteria for Vulnerable (extent of occurrence ~33,700 km2) but the habitat is highly fragmented and there is evidence of increase of salinity in the area and continuing clearing of remnant of vegetation patches reducing the quality of the habitat and extent of occurrence respectively. It is therefore listed currently as Near Threatened (almost qualifies for listing under criterion B1ab(iii)).
|Range Description:||Acacia jacksonioides is endemic to Australia distributed from near Three Springs southeast to near Mount Vernon with a disjunct occurrence east of Geraldton in Western Australia.|
Native:Australia (Australian Capital Territory, New South Wales, Northern Territory, Queensland, South Australia, Victoria, Western Australia, Western Australia)

|Population:||Total population size is not known, it was last collected in 2007.|
|Habitat and Ecology:||Small shrub that grows in gravelly sand or loam, often on hilltops, in scrub, shrubland and eucalypt woodland.|
|Major Threat(s):||There are no known direct threats to the species, however, the Avon Wheatbelt region where this species occurs has been extensively cleared for agriculture and grazed by stock, and subsequently the remnant patches of vegetation are highly fragmented and at risk. Extensive clearing of vegetation has led to salinity problems (expected to affect up to 30% of the region's area). Vegetation clearing still continues and exotic weed invasion and changes in fire regimes are also threatening the habitat (Beecham 2001). The percentage of vegetation cover remaining across the shires in the area where this species occurs range from 4.3% in the Shire of Dowerin to 13.6% in the Victoria Plains Shire (Roadside Conservation Committee 2005).|
|Conservation Actions:||It is not known whether this species occurs within a protected area. Most reserves of the region are small (average reserve area in the Avon Wheatbelt 1 is 452 hectares) and isolated by wheatfields. Management plans have been developed to protect the roadside vegetation in the area to provide corridors for species dispersal between the remnant patches of vegetation (Beecham 2001). This species is not listed as Threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). It is recommended that its seeds are stored as an ex situ conservation measure, that further research is carried out on habitat status and levels of threat and management plans are implemented to secure the future of remnant patches of vegetation.|
