Volume 2 , Part 2, page 190 MacDonnell Ranges Site: 24-2-1 Watarrka Level of significance: national Location: 24 16' S 131 35' E; South West edge of the Macdonnell Ranges uplands. Area: 1243 km2 Map sheet: Lake Amadeus SG 52-4 Bioregions: MacDonnell Ranges (MAC 87.3%) & Great Sandy Desert (GSD 12.7%) Tenure: Wattarka Nat. Park (57% of site); Freehold - Aboriginal Land Trusts (ALT). Haasts Bluff ALT (13%), Petermann ALT (5%), Alatjuta ALT (1%), Watarrka ALT (1%) and Urrampinyi Iltjiltjarri ALT (16%), Land Settlement Aboriginal Corp. (3%) Description: The site is largely circumscribed by the surface geology and topography. It is characterised by the large expanse of horizontally bedded Mereenie Sandstone and associated Cambrian marine sediments - calcareous sandstones, siltstones and limestones. The site also includes the catchment and floodout of Kings Creek. Notes: Arguably the most important site for the conservation of plants in Central Australia. The site supports a remarkable diversity of species and plant communities - over 580 species have been recorded. In additional the site supports an extensive list of rare, threatened and disjunct plant taxa (see below). The largely horizontal bedding of the porous Mereenie Sandstone is largely responsible for this diversity of unusual, rare, endemic and relictual plant taxa. The porous rocks hold the water like a sponge following rainfall events. This water is retained in the catchment and is lost slowly, prolonging the growing season for deep rooted perennials, providing opportunities for germination and establishment. In addition, seepage and springs emerge from the base of the ranges and within shaded gorges. Numerous springs are - at least in recorded history - permanent. Hydrocotyle A39600 Watarrka and Amperea spicata are endemic to the site. It also contains the type localities for Sedopsis filsonii, Amperea spicata, Euphorbia sarcostemmoides and Brachycome blackii.
