Volume 2 , Part 2, page 202 MacDonnell Ranges Site: 23-3-6 Goyder Pass Level of significance: bioregional Location: 23 39' S 132 24' E; Western Macdonnell Ranges Area: 180 km2 Map sheet: Hermannsburg SF 53-13 Bioregion: MacDonnell Ranges (MAC) Tenure: West Macdonnell Ranges National Park (44% of site); Freehold - Ltalaltuma, Rodna and Haast Bluff Aboriginal Land Trusts (each <1% of site); Pastoral Lease - Glen Helen Station (55% of site) Description: This site includes the catchments of three tributaries (including Davenport Creek) of Crawford Creek in the Mereenie Valley. The geology and geomorphology of this area is complex. The north flowing creeks have cut down through the east-west trending strike ridges of the western Macdonnell Ranges exposing various sedimentary geologies including dolostone, limestone and sandstone. The upper catchment of the site is mountainous with high points at around 950 m ASL and is composed of conglomerate. The 'floor' of the Mereenie Valley is an undulating surface with low 'broken' hills formed from the weathering of tertiary material ie duricrusted land surfaces, and poorly consolidated sandstones. In addition, the site includes extensive areas of recent alluvial and colluvial deposition and minor outcroppings of gneiss. Notes: The botanical values of this site have yet to be adequately determined and may extend more broadly particularly to the north towards the Razorback. It is known that the site currently supports extensive stands of mature Acacia shrublands and populations of Brushtail Possums (a rare mammal in central Australia). It is possible that this area supports mound springs and this possibility should be investigated. Criteria satisfied: B1 b1 ii) Taxa of Australian significance: Austrostipa aquarii {3RC-}, Cratystylis A36062 Glen Helen {3RC-}, Sauropus ramosissimus {3KC-} Taxa of NT significance: Einadia nutans subsp. nutans {3rC-}, Eremophila ovata {3k [N,E]}, Pimelea microcephala subsp. microcephala {3r}, Ptilotus aervoides {3k only known in MAC from this site}, Sclerostegia disarticulata {3rC-}, Spartothamnella puberula {3rC-} Taxa of Southern NT (study area) significance: none Taxa of bioregional significance: Polymeria ambigua {MAC (disjunct and southern range limit) [S]}, Trema tomentosa var. viridis {MAC (disjunct)} Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 92 (93 %): Triodia brizoides (Hillside Spinifex) hummock grassland with mixed species low open-woodland overstorey. Map unit 69 (6 %): Acacia aneura (Mulga) tall sparse-shrubland with Aristida contorta (Bunched Kerosene Grass) or Triodia open-tussock/hummock grassland understorey.
