Land systems of the Kimberley Region

DOCKRELL LAND SYSTEM (Dok) 6038 km2 Source: WKY, OVC Rocky, mountain ridges on metamorphic rocks, skeletal soils, open stunted woodlands with spinifex.

State land type: Hills, ranges and plateaux with eucalypt woodlands and spinifex.

Geology: Strongly metamorphosed quartzite, schist, sandstone, slate, and shale, with quartz veins and dolerite intrusions.

Geomorphology: Formed by dissection of the Kimberley surface - plateaux and mountain ranges: mountain ranges in strike belts up to 22.5 km wide, with closely-spaced strike ridges above the level of, or produced by dissection of, restricted lateritized remnants, and with strike-aligned valley plains; dense rectangular pattern of incised drainage with

strike-controlled trunk drainage; relief up to 150 m.

Land management: A rough hill system with hard spinifex vegetation; very low pastoral value, stable, very low susceptibility to erosion.

Low parallel ridges on metamorphic rocks of the Dockrell land system support hard spinifex (Triodia spp.) and isolated small trees of snappy gum

(Eucalyptus brevifolia).

Land systems of the Kimberley Region

ELDER LAND SYSTEM (Edr) 1249 km2 Source: OVC Rugged sandstone hills in the central-western part of the Ord Victoria survey area.

State land type: Hills, ranges and plateaux with eucalypt woodlands and spinifex.

Geology: Sandstone. Upper Devonian (Elder Sandstone).

Geomorphology: Sandstone structural plateaux (asymmetric basin) and sandstone- shale cuestas (asymmetric basin).

Drainage: Angular and rectangular patterns of moderate to high intensity.

Land management: Most of the system falls within the Purnululu National Park or the Ord River Regeneration project area and is not grazed by cattle. It is inherently stable and not

prone to erosion; controlled burning programs needed to minimise risk of wildfires.

The most spectacular expressions of the Elder land system are the unique sandstone beehives of the Bungle Bungles (Purnululu National Park).
