This replaces NVR2013_COND_V2 and _V2A. Site condition aims to reflect three components - composition, structure and function. In practice, condition is measured through the prism of lifeforms, their cover and species diversity. Measuring the condition of native vegetation recognises that most remaining native vegetation in Victoria has been subject to some disturbances, such as historical land use, grazing or weed and pest animal invasion, and is subsequently reduced in condition; vegetation types vary spatially and temporally; circumstances fluctuate (e.g. seasons, natural disturbance events); degradation and rehabilitation occur; and naturalness is valued.

Purpose:
To contribute to assessments of the impacts on native vegetation at different locations, the "NVR_score", the NVReg versoin of condition score, of this Location dataset is used to determine the amount of loss in accordance with the DELWP's 'Guidelines for the removal, destruction or loppng of native vegetation' (December 2017).
The 'NVReg_score' has a minimum condition score of 0.20; a value of 0.20 was assigned to replace all values lower than 0.20 from the raw condition score into the 'NVR_score'.

This dataset is a model and as such is an indication of likely native vegetation condition. It would be improved by additional stratified and systematic collection of primary data including species diversity and cover.
Logical Consistency:
Data Source:
Dataset Source: The original vegetation condition model is based on generating a frame of reference (benchmarks), generating the current condition by calculating how the observed condition deviates from the benchmark, and modelling the current condition across the landscape. There are two primary data sources are Vegetation plots (50,000+ sites) and Habitat Hectares (20,000+ sites).
