Volume 2, Part 2, page 276 Tanami Site: 20-2-1 Lake Surprise and the Lander River Floodout Level of significance: national Location: 20 7' S 131 30' E; Central Tanami Desert Area: 2021 km2 Map sheets: Mount Solitaire SF 52-4, Tanami East SE 52-16 & Lander River SF 53-1 Bioregion: Tanami (TAN) Tenure: Freehold - Central Desert Aboriginal Land Trust (90% of site) and Karlantijpa North Aboriginal Land Trust (9% of site) Description: This site includes the Lander River downstream of Curlew Waterhole, Lake Surprise and the river's floodout in the cental Tanami Desert. It also incorporates the reticulate dune fields to the east and west of Lake Surprise. The site is predominantly comprised of recent lacustrine, aeolian, and alluvial deposits, although there are minor outcroppings of calcrete, siltstone and claystone on the edges of the Lander River Floodout. Soil textures vary throughout the site from deep dune sands, to clay deposits on the floor on Lake Surprise. Notes: A geomorphologically diverse site, which has rarely been visited by botanists. The reticulate dune systems in the vicinity of Lake Surprise are known to support stands of Eucalyptus camaldulensis var. obtusa. This is also the type location for Corymbia sphaerica and Bonamia deserticola. This site is contiguous with site 20-3-1 (Paleo-Lander River). Criteria satisfied: A1 a i), A1 b i), A2 e i),, B1 b1 i) Taxa of Australian significance: Comesperma A77288 Tanami {3R}, Corymbia pachycarpa subsp. glabrescens {3K [SE]}, Eleocharis papillosa {3R}, Heliotropium subreniforme {3K}, Logania centralis {3KC- [N]}, Olax spartea {3K}, Rothia indica subsp. australis {3KC-} Taxa of NT significance: Centipeda racemosa {3k}, Corymbia candida subsp. dipsodes {3k}, Elacholoma hornii {3rC-}, Gompholobium simplicifolium {3r}, Gomphrena leptophylla {3k}, Heliotropium diversifolium {3k}, Indigofera ammobia {3k}, Phyllanthus carpentariae {3k} Taxa of Southern NT (study area) significance: Cyperus castaneus {(disjunct)}, Desmodium filiforme {(disjunct) only known in TAN from this site}, Gonocarpus chinensis s.lat. {(disjunct)} Taxa of bioregional significance: Acacia kempeana {TAN (northern range limit) [N]}, Calotis erinacea {TAN (disjunct and northern range limit) [N]}, Corymbia sphaerica {TAN (western range limit) [W]}, Euphorbia petala {TAN (western range limit) [W]}, Halgania solanacea var. A4206 Mt Doreen {TAN (eastern range limit) [E]}, Lomandra leucocephala subsp. robusta {TAN (disjunct and northern range limit) [N]}, Paspalidium reflexum {TAN (northern range limit) [N]}, Scaevola basedowii {TAN (northern range limit) [N]}, Stackhousia megaloptera {TAN (northern range limit and disjunct) [N]} Other taxa only known in TAN bioregion (NT portion) from this site: Myriophyllum verrucosum Type locations of the following were collected from the site: Bonamia deserticola (1973), Corymbia sphaerica (1988) Botanically Significant Waterholes at the site: Mallopan Waterhole Vegetation Map Units (mapped as occurring at the site on the 1:1000,000 NT Vegetation Survey Map): Map unit 112 (1 < %): Bare salt pan. Map unit 52 (4 %): Melaleuca glomerata (Inland Teatree) open-shrubland. Map unit 76 (12 %): Triodia pungens (Soft Spinifex), Triodia schinzii (Feathertop Spinifex) hummock grassland with Acacia tall sparse-shrubland overstorey. Map unit 27 (12 %): Eucalyptus microtheca s. lat. (Coolibah) low open-woodland with open-grassland understorey. Map unit 77 (69 %): Triodia pungens (Soft Spinifex), Triodia schinzii (Feathertop Spinifex) hummock grassland with Acacia tall sparse-shrubland overstorey between dunes.
