Abstract

This report details a collaborative project between the Western Australian Department of Primary Industries and Regional Development and CSIRO that focused on developing State and Transition Models (STMs) for mulga rangelands in Western Australia. The overarching aim of the project was to improve the common understanding of the characteristics and dynamics of mulga rangeland ecosystems and the expected impacts of management. Specifically, the project aimed to collate expert knowledge and monitoring information using a nationally consistent framework to develop quantitative and dynamic STMs. The geographic scope of the project covers the extensive mulga rangelands of Western Australia, particularly the Gascoyne and Murchison Interim Biogeographic Regionalisation for Australia (IBRA) regions, as well as parts of the Pilbara and Yalgoo IBRA regions. The study prioritised mulga woodlands and shrublands and chenopod shrublands for model development due to their pastoral importance and history of ecological modification.
