Abstract: This replaces SPECIES_HABITAT_V4_HDNV and _HINV This data series is a set of spatial maps describing importance of suitable habitat within the current extent of native vegetation for some species. These species are threatened and their habitat is described as either dispersed or highly localised (ie remaining habitat within Native Vegetation is either greater than or less than 2000 ha respectively based on IUCN categorisation). These maps have been developed for use in the native vegetation permitted clearing regulations. Thresholds have been applied to the maps because lower likelihood areas do not receive species-specific consideration in the assessment process. Habitat importance is continuous for dispersed species, for highly localised habitats however it is equal across the map. The values stored in these data are used to calculate risk and offsets under the native vegetation permitted clearing regulations (as proposed 2013)

Note that for dispersed species the values stored in these data must be divided by 100 to calculate the habitat importance score.

Purpose: To support species specific considerations associated with Native Vegetation Clearing Regulations (as proposed 2013) It is important to understand the distribution of a species' habitat as part of making decisions that enable species to persist in the future. Such information enables: - biodiversity planners and managers to know where species' habitat is or is likely to be, or where it is more likely to be within the species' recorded distribution - guidance on survey effort that might be most useful to find new locations of species or to identify suitable habitat for translocations for species recovery. -guidance on where to locate reserves to protect particular species or where management should be concentrated. -land use and statutory planning processes to consider the relative impacts of a proposed development on species habitat needs These models are: - primary input to Location Risk for Native Veg Regulation (NVR2013_LOCRISK_V2)

Atribute Accuracy: These data are a combination of site observations and models and as such are indications of the importance of habitat. They do not however take into account the current condition of the habitat for the particular species, apart from an indication of the presence and context of native vegetation - Some species are known to predominantly inhabit non-native vegetation. This modelled data component does not capture this. Models of habitat are not intended to equate with species presence. Other factors such as natural disturbances, losses due to historic catastrophes, and the impact of predators and seasonal factors influence whether a species is present in habitat at any given time. Also these data are highly reliant on survey records that indicate the suitability of a particular environment for a species. New records may influence future spatial models of suitable habitat.
Logical Consistency: Includes species point data from VBA where no model exists or in addition to model
Data Source: Species' Habitat Distribution (SPECIES_HABITAT_V4_HPNV) Landscape Context of Native Vegetation 2010 (unpublished) 1. Thresholds were applied to Pre1750 habitat distribution suitability models (v3) were produced by ARI and areas of low habitat suitability were removed 2. Each resulting model for dispersed species was combined with the landscape context model for native vegetation: Square root of (suitability X NV context) 3. Each resulting habitat suitability model for highly localised habitats was combined with point observation data from the Victorian Biodiversity Atlas. 3. For species where there was insufficient data to create a model, the habitat importance map uses point observations from the Victorian Biodiversity Atlas only
