The management of native vegetation is undertaken by various government and non-government agencies at the regional, state and federal level. Such agencies use information about the level of depletion and, more recently, the 'condition' or 'quality' of native vegetation. Monitoring changes in the coverage and condition of vegetation allows the calculation of 'net gain' in both the extent and quality of native vegetation across the State. ARI staff have been developing a range of novel datasets to assist land managers to make informed decisions about the management of native vegetation and conservation programs.

Existing datasets included a series of maps that detail the types of vegetation across the State. While these are integral to managing native vegetation resources, they did not capture well the extent of non-woody or grassy types of native vegetation. Using remote-sensed imagery, GIS data and custom-developed software a more consistent appraisal of the extent of both woody and grassy vegetation types have been produced, as well as an assessment of the rates of loss and gain in these vegetation forms over a 10 year period.

Additionally, similar technology was used to produce a first-ever model / map of native vegetation condition across Victoria. Using approximately 17,000 'Habitat Hectare' assessments, along with satellite and other data, the resultant maps display ecological condition covering most of south-eastern Australia. The maps will also provide a baseline for the continued monitoring of native vegetation into the future, as well as a more rigorous basis for making natural resource management decisions e.g. NaturePrint.
