Reporting on rangeland condition and trend across State boundaries is possible due to the complementary nature of the respective States' rangeland monitoring systems. While the State monitoring programs have evolved for different reasons, a commonality of core attributes makes cross jurisdictional reporting possible. Woody plant density, composition and cover are such attributes that have been measured in the southern rangelands of Australia for the past decade or so. The ability of the current monitoring programs to report at a regional or vegetation community scale enables Interim Biogeographic Regionalisation of Australia (IBRA) regions to be used as logical units for national reporting. This paper provides a first attempt at cross jurisdictional reporting.

An increase in woody plant density and cover was found for all reporting IBRAs across the southern rangelands in the last decade. Similarly an increase in recorded species diversity can be noted for all but one IBRA.
