This polygon shape file is a 1:25,000 – 1: 50 000 environmental dataset combining 14 input data sources. These are outlined in the lineage statement. The input data sets identify agreed HEV criteria for the purposes of regional strategic planning and other environmental assessment projects that require identification of significant biodiversity values. This project was undertaken by Planning Services Unit, OEH with input from all the Planning teams in Regional Operations, OEH. The Central West Orana High Environmental Values dataset covers the Central West Orana Regional Growth Planning area. There is a data gap in the mapping between the Central West and the Central Tablelands CMA boundaries due to a portion of the statewide coverage of vegetation mapping (STVM) products not being complete.
