Vegetation association mapping undertaken as part of a resource and fire behaviour assessment for Pilliga Nature Reserve and Warrumbungle National Park in 1990. Existing datasets were collated and field survey undertaken to inform air photo interpretation of vegetation patterns. 36 field survey sites were sampled in the Pilliga. Number of sites sampled in the Warrumbungles is not recorded. Specifications of aerial photography is not provided, however 1:50,000 air photos were flown over the Pilliga and part of Warrumbungles in 1989, and 1:50,000 photos captured in 1982 exist for the remainder of Warrumbungle NP. The purpose of the project was to provide an overall picture of the vegetation types and to sample fuel loadings stratified by vegetation type/physiology/aspect for incorporation into the NPWS FIREMAPS (Fire Mapping and Prediction System) and ERMS databases.
