This report has been prepared for the joint Commonwealth/State Steering 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.



Project Objectives

This project was undertaken to identify the conservation needs of flora and fauna species in the Upper North East (UNE) and Lower North East (LNE) regions. It was managed jointly by the NSW National Parks and Wildlife Service, State Forests of NSW with Environment Australia (Commonwealth), as the lead agency.



Methods

Flora and fauna were treated in separate assessments. The work began with NSW National Parks and Wildlife Service compiling lists of forest dependent fauna and flora in the region. Expert ecologists were asked to provide information on the habitat and critical resource requirements, ecological attributes and the disturbances affecting the listed species. Some novel analyses were used to estimate the area of land needed for the conservation of species which were rated as the highest priority.

Experts also provided information to help apply the targets in an ecologically meaningful way. This included recommendations on, distinct populations, dispersal distances and barriers.

The main chapters of this report cover the methods and results of the project. Appendices provide lists of species, lists of experts, and detailed tables of results.



Results

The outcomes of this project will be used, firstly, to guide the design of reserves in the UNE and LNE regions so that the habitats of the most threatened species are protected. Secondly the results are also intended to help the management of forested land over both the regions.
