The majority of Giant Gippsland Earthworm (GGE) habitat in the Strzelecki Ranges has been cleared for agriculture. GGE can survive well under pasture but need protection from threats such as changes in the soil moisture, soil compaction and pugging by cattle. Revegetation of dense, high water-usage species can dry out GGE habitat. One of the aims of this project is to protect GGE habitat while demonstrating the planting of indigenous vegetation adjacent to colonies that once grew in the south- western Strzeleckis before European settlement. This is achieved by fencing GGE habitat to protect them from grazing pressures such as compaction and pugging and creating a buffer around the colonies where a modified planting method is used in different buffer zones. This includes lower planting densities and selection of specific lifeforms from the appropriate Ecological Vegetation Class (EVC). EVC is a classification system used as a basis for plant selection for revegetation projects across Victoria. An EVC consists of one or a number of floristic communities that appear to be associated with a recognisable environmental niche. Each EVC is described by a combination of its structure, floristics, life- form and reproductive strategy features, and through an inferred fidelity to particular environmental parameters. The descriptions below are general descriptions for the EVCs but the species lists have been refined and are specific to the south-western Strzeleckis where the GGE is found. The modified planting design is characterized by the creation of three zones, each of which requires different planting regimes chosen from the appropriate EVC (species composition and density). Broadly, the three most commonly found EVCs in GGE habitat (pre-European settlement) are Wet/Damp Forest, Swampy Riparian Woodland and Warm Temperate Rainforest. To simplify the modified planting guidelines in Giant Gippsland Earthworm habitat, the EVC revegetation species lists and planting densities have been combined for some of the landforms.

Bioregion: A landscape-scale approach to classifying the environment using a range of attributes such as climate, geomorphology, geology, soils and vegetation. There are 28 bioregions identified within Victoria and the Giant Gippsland Earthworm habitat is within the Strzelecki Ranges bioregion. Ecological Vegetation Class (EVC): The standard unit for classifying vegetation types in Victoria. EVCs are described through a combination of floristics, lifeforms and ecological characteristics, and through an inferred fidelity to particular environmental attributes. Each EVC includes a collection of floristic communities (i.e. lower level in the classification) that occur across a biogeographic range, and although differing in species, have similar habitat and ecological processes operating.
