Landscape-scale issues such as feral animals, altered fire regimes and invasive species are still threats. Resourcing to address particular issues is patchy and not undertaken in a holistic manner

Although there are exceptions associated with invasive species or management regimes, the degree of modification of most vegetation outside the intensive land-use zones is relatively small. The proportion of each major vegetation group classified in VAST categories I or II (residual or modified) averages 80%
