This project has been jointly funded by the New South Wales and Commonwealth Governments and managed through the Resource and Conservation Division, Department of Urban Affairs and Planning, and the Forests Taskforce, Department of Prime Minister and Cabinet.
This project has been overseen and the methodology has been developed through the Environment and Heritage Technical Committee which includes representatives from the NSW and Commonwealth Governments and stakeholder groups.
The project has been overseen and the methodology has been developed by Environment Australia. NSW National Parks and Wildlife Service oversaw and developed the methodology for the identification and assessment of centres of endemism.

Executive Summary


This report has been prepared for the joint Commonwealth/State Senior Officials Committee, which oversees the comprehensive regional assessments of forests in New South Wales.
The comprehensive regional assessments (CRAs) provide the scientific basis on which the State and Commonwealth governments will sign regional forest agreements (RFAs) for the major forests of New South Wales. These agreements will determine the future of the State’s forests, providing a balance between conservation and ecologically sustainable use of forest resources.
As defined in the Australian Heritage Commission Act 1975, the national estate comprises:
those places, being components of the natural environment of Australia, or the cultural environment of Australia, that have aesthetic, historic, scientific or social significance or other special value for future generations as well as for the present community.
This report was undertaken to document the methodology and rule-sets used to identify potential areas of natural national estate significance. The work was undertaken by Environment Australia (EA) and NSW National Parks and Wildlife Service (NPWS) in consultation with State Forests New South Wales (SFNSW).
The process of identifying potential national estate involved asking a series of expert panels to identify species, known areas or landscape features (such as rock outcrops for example) that met the requirements for national estate criteria. The outputs from these workshops were combined with the result of literature reviews and the experience of previous CRAs to create rule-sets. Where available, separate rule-sets were used for species based analysis and the identification of landscape features or areas. Rule-sets were then applied to data gathered during CRA assessments. The results of different rule-sets were cross-validated to generate the final set of layers. These are expressed in terms of relevant criteria. Areas identified in this report as having potential national estate value are indicative only and are not necessarily the delineated forested areas that will be listed in the Register of the National Estate.
The results of these analyses are presented here.
Note: All area calculations contained in this report are based on grid analysis and are therefore have a minimum resolution, in most cases 100 m (one hectare) for localised values and 500 m (25 hectares) for extensive values. Consequently, all area figures should be regarded as indicative only.
