This report was compiled by Bruce Cummings and Ann Hardy of the National Reserves System Section (NRS), Environment Australia. We would like to acknowledge the major contribution of State personnel in the revision of bioregion boundaries and providing regional descriptions, and Gethin Morgan in providing advise on appropriate boundaries and the delineation of IBRA sub-regions in particular.
A technical workshop was held at Environment Australia in Canberra on Monday 24 July 2000 to review cross-border issues in relation to IBRA and sub-region boundaries, to resolve major anomalies in the digital data and to discuss mechanisms to more accurately capture on-ground variation in some regions.
Workshop participants:
| Australian Capital Territory | David Shorthouse (Environment ACT) |
| New South Wales | Rob Dick, Julianne Smart (National Parks and Wildlife Service) |
| Queensland | Gethin Morgan (Environmental Protection Agency) |
| South Australia | Tim Bond (Department of Environment and Heritage) |
| Tasmania | Dave Peters (Parks and Wildlife Service) |
| Victoria | David Parkes (Department of Natural Resources and Environment) |
| Western Australia | Norm McKenzie (Department of Conservation and Land Management) |
| Commonwealth | Richard Thackway (Bureau of Rural Sciences) Jim Tait (National Land and Water Resources Audit) Bruce Cummings, David Forsyth, Ann Hardy (NRS) |
The implementation of a series of National Land and Water Resource Audit projects funded through the National Heritage Trust which utilise IBRA as a reporting framework provided the final catalyst for this IBRA update, in particular the Landscape Health Project. This project is a joint project between the NLWRA and the State of the Environment Reporting and National Reserve System Sections of Environment Australia. It was scoped and managed initially by Ian Cresswell (NLWRA), Allan Spessa (SoE) and David Forsyth (NRS), and then later by Jim Tait (NLWRA), Gary Whatman (SoE) and Bruce Cummings (NRS). Gethin Morgan was employed as a consultant to collate and analyse, in consultation with the States, a suite of environmental attributes within an IBRA and IBRA sub-region framework.
This Summary Report contains excerpts on the history of the development of the IBRA framework from Thackway and Cresswell 1995.
