Grassy woodland states reflecting the degree and permanence of anthropogenic disturbance and intensification are used to describe EA
| Title/code for 'state' | Brief description | Detailed description |
|---|---|---|
| 1A | Grassy woodland with a very diverse native ground-layer | Tree (canopy) cover >50% and the ground-layer has a high diversity and cover of native species (> 30 species and >70% groundcover of native species). Never fertilised or fertiliser use ceased 3–4 decades previously |
| 1B | Derived native grassland with a very diverse native ground-layer | There is low tree canopy cover, but the ground-layer has a high diversity and cover of native species (> 30 species and >70% groundcover of native species). Never fertilised or fertiliser use ceased 3–4 decades previously |
| 2A | Grassy woodland with a diverse native ground-layer | Tree canopy cover is slightly lower than 1 A (20–35%) and the ground-layer has a slightly lower diversity and cover of native species compared to 1 A (16–29 species and 50–69% groundcover of native species). Rarely fertilised or fertiliser use ceased 2–3 decades previously |
| 2B | Derived native grassland with a diverse native ground-layer | There is low tree canopy-cover (5–9%), but the ground-layer has a good diversity and cover of native species (16–29 species and 50–69% groundcover of native species). Rarely fertilised or fertiliser use ceased 2–3 decades previously |
| 3A | Some mature remnant trees present and a moderately diverse, mainly native, ground-layer | Mature remnant eucalypts present but with no tree regeneration. The ground-layer has a moderate diversity of native species (8–15 species) and 30–49% native-ness of the ground-layer. Some exotic species are present. Historically low-moderate fertiliser application. Most recent fertiliser application may have been within past five years |
| 3B | A moderately diverse and mainly native grassland with few trees | Few mature eucalypts present (but with no tree regeneration). The ground-layer has a moderate diversity of native species (8–15 species) and 30–49% native-ness of the ground-layer. Some exotic species are present. Historically low-moderate fertiliser application. Most recent fertiliser application may have been within past five years |
| 4 | Grassland a mix of native and exotic species and occasional scattered trees | Grassland with 4–7 native species, <30% cover of native species and the occasional remnant tree with no natural tree regeneration. There has been frequent fertiliser application until present day |
| 5 | Predominantly exotic grassland with a few native species. No remnant trees present. | No remnant trees remaining and no natural tree regeneration. Pastures are predominantly exotic with <3 native species and <10% cover of native species. There has been frequent fertiliser application until present day |

Transitions between states are also applied to the individual ecosystem assets. Model adapted from the simplified Box Gum Grassy Woodland State and Transition model in Whitten et al. (2010)
