Camelgooda land system (Cml), size: 17,826km2, publication source: WKY
Extensive dunefields, pindan and other low woodlands.
Location map showing coverage of Camelgooda land system defined by black region.
State land type: Sandplains and dunes with pindan woodlands and spinifex/tussock grasslands.
Geology: Quaternary aeolian sands.
Geomorphology: Sandplains and dunefields, with little organised drainage: stable dunefields with swales opening locally into sandplain; restricted marginal plains with thin sand cover occur adjacent to dissected tracts and there are minor, isolated hills up to 60m high; limited surface drainage mainly as sheet-flow in tracts downslope from uplands and extending for short distances into dunefields; relief up to 12 m.
Land management: System is not generally prone to degradation or erosion although recently burnt areas have minor susceptibility to wind erosion but stabilise rapidly after rain. Control of grazing pressure and frequency of burning is desirable.

Table of Camelgooda land system – land units. * Numbers in brackets refer to soil family or vegetation community/alliance in ‘General report on lands of the West Kimberley area, WA’ (Speck et al. 1970); + Pasture types described in Appendix 1; Note: Proportions and occurrence of pasture types within land units are subject to change over time due to invasion by native and introduced species, seasonal conditions, fire frequency and grazing management.
Dunes: linear, up to 12m high and 32km long, with narrow uneven crests; flanks slope 315% on north side and up to 20% on south.
Deep red sands: Cockatoo family (7).
Low woodland of bloodwood and/or Bauhinia with prominent tall shrub layer characterised by Acacia spp. and Triodia bitextura, Triodia pungens, and T. bitextura - Chrysopogon spp. ground storeys. Corymbia dichromophloia and Bauhinia cunninghamii alliances (10, 38a, 38b); crests 38c, locally 55.
Swales and sandplain: swales to 1.6km wide with flat floors and concave marginal slopes up to 2%; locally opening into sandplain up to 3.2km.
Reddish sandy soils: Yabbagoddy family (1).
Low scrubby woodland with prominent tall shrub layer and Triodia bitextura - Chrysopogon spp., ground storeys, C. dichromophloia and Grevillea striata alliance(10, 8c, 12, 34a); locally 34b, 37b, 57.
