Land Resource Mapping

1182167490_sub_region_-_land_mapping.jpg The Desert Uplands Committee identified the need for detailed land resource information at a scale that relates to individual properties (i.e. 1:100000). Previous to this project, only the north-east and central area of the bioregion were mapped at that scale - an area of approx. 26.000sq.km.

The remaining 44,000 sq.km were mapped on a land system basis at 1:500000: a scale that identifies complexes of land types and was, therefore, too general to provide the information that is necessary for planning and implementing management practices required for sustainable land uses.

This project collated the data of previous surveys and together with remote sensing techniques and air-photo interpretation, identified and mapped individual soil-vegetation associations. Extensive field work over three years provided the data on soils and vegetation to assess the limitations, capabilities, biodiversity and condition of each land type. This data has been entered onto a powerful database to allow summaries of all of the different land types to be linked to GIS maps. The Land Resource Mapping project was completed and launched in November 2003.   This information is an invaluable management tool for land managers and is available on CD from the Desert Uplands office or on EPA's Website
