This layer delineates broad agricultural land uses in Victoria. LUSE250_1991 was created by manually interpreting 1991 LANDSAT TM satellite data and incorporating forest cover boundaries from FORCOV500-87. The land use boundaries have been registered to 1:500,000 topographic features. (not current - see revised LANDUSE250)

Structural vegetation mapping of forest in Victoria based on the Land Conservation Council (LCC) vegetation classification scheme. The layer is independent of land tenure and is a combination of existing data from multiple sources (predominantly LCC) and primary mapping based on satellite image interpretation. Using histoirc 1:63,360 forest maps as a source.

Modelled dataset of Native Vegetation and major water-based habitats, created by the Arthur Rylah Institute, and completed July 15th , 2007 NV2005_EXTENT has been created from time-series(between 1989-2005) Landsat Imagery, many thousands of ground-truthing points, other relevant spatial data and expert validation. The dataset is a good interpretation of native vegetation extent (including aquatic habitat), but must be used with care, given it's modelled nature. The dataset categorises the landscape into eight categories ranging from 'highly likely native vegetation' through to 'unlikely to support native vegetation'.

This dataset is a modelled dataset of the quality of Terrestrial Native Vegetation as per the "Habitat Hectares" approach (Parkes et al, 2003). Specifically it is a model of the "Habitat Score" which is an index comprising ten (10) separate metrics that are weighted and summed. Seven (7) of these are site-based vegetation condition metrics, referred to collectively as the "Site Score" and three(3) are related to the spatial context of the site and referred to collectively as the "Landscape Score". The Site Score comprises 75% of the final quality score and the Landscape Score makes up the other 25%. Site Score Components: Large Tree Score (10), Canopy Cover Score (5), Understorey Score (25), Litter Score (5), Log Score (5), Weed Score (15), Recruitment Score (10) Landscape Score Components: Patch Size/Shape (10), Neighbourhood &Connectivity (15)

This layer is not current (see LBPZONE25) but it maintained for historical purposes. A zoning of forest into suitability of habitat for Leadbeater's Possum (LBP) (Gymnobelideus leadbeateri), based on a visual interpretaion of aerial photographs to identify certain density classes of stags, followed by refinement based on ground survey.

Polygons delineating vegetation units defined by the Land Conservation Council (LCC). Forest species and structure are defined for each LCC Study Area.

The dataset describes probable land-use history sequences between 1837 and 2005 for all land parcels in Victoria. The final dataset (Land Use History ECOLOGICAL SUMMARY (1837-2005) = LUHIST2005_VIC) consists of 50 categories. All cells belonging to the same category share a common history.

Polygon coverage delineating Victorian forest types. Key attributes referenced through a forest type code include dominant and two associated species, maximum and minimum height, and maximum and minimum projective foliage cover.

This layer identifies Forest Cover Changes in Victoria from 1972 to 1987. Forest Cover is defined as woody vegetation greater than 2 metres in height and with crown cover (foliar density) greater than 10%. The smallest unit of forest mapped was fifteen (15) hectares.

This land use map has been prepared under the NLWRA (NHT) project of Theme 5 (Land use change, productivity and Sustainability) for Gippsland. The map refers to the year 1996-97 and is based on 4 sources of information: (1) Resource data sets of Victoria held at CGDL, DNRE, (2) Satellite imagery, (3) ABS Agricultural Statistics, and (4) Field information. The land use classification scheme that has been followed in this map was developed at a workshop convened by BRS and contributed by Commonwealth and State staff in May 1999. The scheme is a modification of a classification proposed by Baxter and Russell in 1994 for the Murray Darling Basin. The classification is hierarchical in nature, identifying primary, secondary, and tertiary levels. The five primary levels show a hierarchy in terms of human intervention in natural environment.
