This report describes a project undertaken as part of 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 major forest areas of New South Wales. These agreements will determine the future of these forests, providing a balance between conservation and ecologically sustainable use of forest resources.
This report was undertaken to provide accurate data on threatened vascular flora of the Upper and Lower North East CRA regions in time to contribute to the development of a comprehensive, adequate and representative reserve network in north-east New South Wales.
To achieve this end, targeted flora surveys were initiated to provide information on the distribution, population attributes, ecology and threatening processes pertaining to priority vascular plant species in the Upper and Lower North East CRA regions. Species included within the scope of this project are those listed under the NSW Threatened Species Conservation Act (1995), or the Commonwealth Endangered Species Protection Act (1992), or which have been identified by expert working groups as warranting regional threatened status.
Data collation of existing records of significant plant species was also undertaken, as was a process of data checking and validation. 252 populations of 48 target plant taxa and 848 incidentally recorded populations of 342 significant plant taxa were located and assessed in the course of this project.
Key Results and products
New populations were located, based on searches of areas considered potential habitat, for 34 of the target taxa. This indicates that targeted surveys utilising expert knowledge of the habitat requirements of rare plants are a very effective method of increasing the knowledge base for these species. A highlight of the field surveys was the outstanding number of populations of significant plant taxa which were recorded incidentally during this project. Populations of 26 species listed as Endangered under the NSW Threatened Species Conservation Act (TSC) and populations of 35 species listed as Vulnerable under the NSW TSC Act were incidentally recorded during this project. These results, in combination with the data validation process conducted as a part of this process, produced a very high quality data set with which species modelling, population viability analysis and conservation requirements studies could be undertaken for the Upper and Lower North East CRAs.
