The EnSym Native Vegetation Regulations (NVR) tool has been developed to assist people who need a permit to remove native vegetation or who want to establish an offset site. It also helps identify areas in the landscape that would meet species offset requirements for proposed native vegetation removal.

The EnSym NVR Tool can be used to test clearing and offset scenarios prior to submitting final versions to the Department of Environment, Land, Water and Planning (DELWP) for processing. The tool can also be used to identify areas within Victoria that provide habitat for a specific set of species. For more information on the native vegetation removal regulations visit:

The EnSym NVR Tool uses information contained in GIS shapefiles to determine implications in accordance the native vegetation removal regulations and the Native vegetation gain scoring manual. It uses ESRI shapefiles, projected in VICGRID94 and in the Datum – Geocentric Datum of Australia 1994. These shapefiles are assessed against the following mapped layers:

  • Native vegetation location map
  • Native vegetation condition map
  • Strategic biodiversity value map
  • Habitat importance maps for Victoria’s rare or threatened species.

The outcome of this assessment is presented in Scenario Testing Reports. These reports can be used to determine preferred alternative layouts. Final reports from DELWP will be needed when applying for a permit to remove native vegetation or providing evidence of gains at offset sites.

Instructional videos on how to install and use the EnSym NVR Tool are provided below. There are four videos showing - how to setup the tool, how to process clearing data, how to process offset data and how to use the species intersection tool (note that these refer to the 2013 version of the tool but operation in the 2017 version of EnSym is fundamentally the same):
