Rangeland inventory and condition survey in part of the Broome Shire

Page last updated: Thursday, 14 June 2018 - 10:39am

The Department of Primary Industries and Regional Development (DPIRD) surveyed the rangelands in part of the Broome Shire in Western Australia between 1989 and 1990. The report of this survey provides land managers, advisors and administrators with a baseline record of the natural resources of the region’s pastoral leasehold land, to assist with planning and implementing land management practices.

How to use this survey

Inventory and condition survey data assists people in the pastoral industry to plan the sustainable use of existing natural resources and the protection of those areas suffering from degradation or at risk of degradation.

The surveys identify and describe the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. They also assess the impact of pastoralism and make land management recommendations, including recommended carrying capacities for each pastoral lease.

Fourteen condition and inventory surveys have been published since 1972. Most of Western Australia’s rangeland pastoral leases have been surveyed, except for pastoral leases in the Southern Goldfields region and to the north-east of Wiluna–Meekatharra. The 15th rangeland survey — in the Southern Goldfields region, covering the area known as the Great Western Woodlands — will be completed in 2018.

Survey area and inventory summary

This survey of part of the Broome Shire covers about 8664 square kilometres of pastoral land in the Canning Basin region (Figure 1). It lies adjacent to the west coast of the Broome Shire, which is in the south-west of the Kimberley region of Western Australia. The survey was undertaken by WE Cotching between 1989 and 1990. It was published as Technical bulletin no. 93 An inventory of rangelands in part of the Broome Shire, Western Australia.

The survey area is dominated by extensive sandplains and dune fields which border the northern edge of the Great Sandy Desert. A smaller area of coastal plain occurs on the western edge of the survey area. Soils on the sandplain and dune fields are predominantly deep red sands and loamy sands. Coastal plain soils are light grey silty clays.

Pastures are dominated by spinifex communities on the sandplain with halophytic species dominating pastures on the coastal plain. There are no permanent watercourses in the area, although there are several springs on the inland margin of the coastal plain. Livestock are almost entirely dependent on man-made watering points.

Condition summary

The survey report includes condition statements for the whole survey area and for each land system.

Pasture and soil condition was assessed for 1128 points throughout the survey area during 1989 and 1990. Findings include:

  • 63% of these points were in good rangeland condition
  • 21% were in fair rangeland condition
  • 16% were in poor rangeland condition.
