BOX GUM GRASSY WOODLAND Photographer: Greg Steenbeeke INTRODUCTION All part of a Community Unfortunately large areas of this community have been Ecological communities are groups of plants, animals and other cleared across our catchment and remaining fragments are listed as organisms that naturally occur together. The structure and critically endangered. The woodland and its waterways provide an composition are determined by environmental factors such as essential home to many of our catchments’ most threatened species. climate, landscape position, soil, aspect and altitude. Box Gum Grassy Woodland is listed as a threatened ecological While a particular ecological community will vary in structure and community under both the Australian Government’s Environment composition across its range, there are common elements that Protection and Biodiversity Conservation Act 1999 (EPBC Act) and the clearly identify one ecological community as distinct from another. NSW Threatened Species Conservation Act 1995 (TSC Act). Activities which affect the condition or extent of Box Gum Grassy Woodland Ecological communities also exist in different condition ‘states’, may require consent or approval. each with defining characteristics. States range from high quality to degraded with several in between. Where does the community occur?

Managing and enhancing biodiversity on your land helps build a resilient landscape that balances production and conservation Description Identification Box Gum Grassy Woodland has a canopy of widely spaced trees dominated by eucalypts (usually Eucalyptus albens, E. melliodora and/or E. blakelyi) with a ground layer dominated by tussock grasses and a high diversity of herbs. Sparse shrubs may also be present. In the Nandewar bioregion, the community may be dominated by E. moluccana or E. microcarpa. This community can occur in one of three states: 1. With an overstorey of trees but no substantial native understorey, 2. With a native understorey, but no trees, or 3. With both trees and a substantially native understorey. For the purposes of the EPBC Act, the presence of a substantially native understorey (with or without trees) is required for a community to be defined as Box Gum Grassy Woodland. Where the understorey does not consist of predominantly native plants, it is considered to be degraded and no longer a viable part of the ecological community. A patch with predominantly native understorey will have mostly native perennial grasses, with at least 12 non-grass, native species such as lilies, orchids and other wildflowers. At least one understorey species must be an important indicator of condition (for example Kangaroo grass). Patches with trees must be greater than 2 hectares, but without trees a patch can be greater than 0.1 hectare. Derived Grasslands Derived grasslands would have originally had a canopy of the dominant Box Gum Grassy Woodland tree species and a species-rich understorey of native grasses, herbs and forbs. In some cases most or all of the trees have been removed, but the intact grassy understorey still remains. These areas are still valued as habitat. As a rule of thumb, if you have an area dominated by perennial native grasses with scattered wildflowers, with or without a canopy of the listed trees, it could be Box Gum Grassy Woodland. Seek further advice from Local Land Services before making significant impacts. What is not Box Gum Grassy Woodland? • Forest or woodland that has a predominantly shrubby understorey (greater than 30%). • Forest or woodland with the canopy dominated by different eucalypt species (such as E. viminalis). • A woodland with native trees, but predominantly exotic species in the understorey.
