N2  - Acacia meiantha Tindale & Herscovitch, (Fabaceae) a low to medium shrub with root suckering, is only known to occur at three locations, Clarence, Carcalgong and Mullion Creek in Central West New South Wales. These disjunct populations each separated by >60 km, are considered as isolated subpopulations. A compilation of recent field surveys shows that of the 42,000 stem clusters/aggregates of Acacia meiantha estimated across the three geographic locations, the majority, 39,900 (96%) occur in the Mullions Range State Forest subpopulation, where 61% of clusters occur in the remnant native forest areas and 39% in the plantation forestry compartments. At Carcalgong 1,566 stem clusters were recorded along narrow roadside reserves. The Clarence subpopulation consists of < 400 stem clusters precariously situated among a confluence of road, railway and electricity power-line easements. Ecological observations of habitat are presented; information relating to genetic diversity, seed biology, reproductive biology and response to fire is found to be Data Deficient. The threatened species listing as Endangered under both State and Commonwealth legislation is warranted; the species does not occur on any conservation lands, has restricted distribution and abundance, and is vulnerable to ongoing threats. The area (AOO) and extent of occupancy (EOO) are calculated. It occurs at three locations (< 5), has an estimated EOO of 2,900 km2 (< 5,000 km2) and an AOO of 80 km2 (< 500 km2) (IUCN (2019) thresholds in brackets); there are significant threats to the extent and quality of habitats. Additional opportunities for improving the conservation of the species, particularly in the Mullions Range State Forest, over and above those outlined in the site-managed initiatives of the current Saving our Species program, are presented.
