The monitoring of biodiversity can be hampered by a lack of systematic information. One approach to overcoming this is to use a standardised environmental accounting framework. This study examined changes in the extent and condition of Critically Endangered White Box-Yellow Box-Blakely’s Red Gum Grassy woodland since it was listed, using the System of Environmental-Economic Accounting. The compilation of environmental-economic accounts was able to reconcile and integrate a range of data sources, with 288 accounts produced. These environmental-economic accounts can be used to monitor and conserve box-gum grassy woodlands and provide a platform for further work, and in particular for accounting for ecosystem services.
