This boundary defines the South West Forest Region of the State used in the Regional Forest Agreement (RFA). The Comprehensive Regional Assessments undertaken by the State and Commonwealth used this boundary to assess forest management, environmental, heritage, economic and social targets to negotiate the Regional Forest Agreement. The initial RFA agreement was signed off in 1999 - the RFA assessment boundary has been static since the completion of the original process. Originally negotiated by DPaW and the Commonwealth, the boundary generally follows, or in part there of, other boundaries such as Interim Biogeographical Regions of Australia ( IBRA ), DBCA's (then CALM), regional boundaries, Mineral Leases etc

IBRA Version 6.1 is the result of refinement of the IBRA Version 5.1 and version 6.0 boundaries due to better data availability amongst some states and territories and also based on alterations by the states/territories along the state borders. The refined boundaries were jointly defined by the Commonwealth, State and Territory nature and conservation agencies. Those jurisdictions to refine their data in this version of IBRA include New South Wales, Queensland, Victoria and Western Australia. There are 53 newly named sub regions and 5 have been renamed from version 5.1. Whilst there has been a refinement of sub-regional and associated bioregional boundaries in Qld, Vic and western NSW, the new sub-regions are found principally in eastern NSW. In WA changes relate to moving the western boundary of Yalgoo bioregion to the coast, truncating the northern portion of the Geraldton Sandplains bioregion. Nominal attributes that make up IBRA are: climate, lithology/geology, landform, vegetation, flora and fauna, and landuse. The use of these attributes varies across the jurisdictions and for further information individual jurisdictions should be contacted.CC - Attribution (CC BY) This data has been licensed under the Creative Commons Attribution 3.0 Australia Licence.

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

Interim Biogeographic Regionalisation for Australia (IBRA) Version 7.0 Bioregions represents a landscape based approach to classifying the land surface of Australia. The framework was first described by Thackway and Cresswell (1995). IBRA 7.0 data consists of two hierarchical `Bioregion' datasets described as part of the regionalisation framework for Australia; 1) Regions - larger scale regional classification of homogenous ecosystems & 2) Subregions - a more localised, finer scale classification of ecosystems within the Region boundaries. Each Bioregion reflects a unifying set of major environmental influences (such as geology, landform patterns, climate & ecological features) which shape the occurrence of flora and fauna associations and their interaction with the physical environment across Australia and its external territories (excluding Antarctica). IBRA Version 7.0 describes 89 Regions and 419 Subregions and is the result of updates to the previous version, IBRA Version 6.1 This record represents Australia-wide IBRA Version 7.0 Regions and Subregions.

Purpose

IBRA is the National Reserve System's planning framework; it was developed as a fundamental tool for identifying reservation targets towards developing a comprehensive and representative reserve system in Australia.

Dataset History

IBRA Version 7.0 is the result of changes to certain IBRA 6.1 boundaries with edge-matching along state borders. The updated boundaries were jointly defined by the Commonwealth, State and Territory nature and conservation agencies. There have been significant changes in Queensland and South Australia. In addition the dataset was also updated to more closely conform to the Geoscience Australia (GA) 1:100K Coastline and State borders. Various sources were used to delineate islands - these included the GA 100K Admin layer plus the Australian Maritime Boundaries dataset, a Coral Sea dataset (held in ERIN) and the GA Commonwealth Fisheries 2006 dataset. In South Australia, the work undertaken by the CSIRO to map the `Environments of South Australia' (see Laut, et. al. 1977) has formed the basis for the mapping of IBRA boundaries for the state. In 1995 the environmental association units, described as part of this work, were reviewed and aggregated to initially form IBRA Regions for the first version of IBRA (Version 4.1). In 2000 an update to create IBRA Version 5.1 incorporated a finer scale level of mapping in the IBRA dataset with the delineation of IBRA Subregions; as part of the hierarchy formed by the IBRA framework Subregions are aggregated to form the boundaries of the IBRA Regions. In South Australia, the environmental associations were interpreted again to form the basis for IBRA Subregions. In 2005 the Subregion boundaries in the South Australian pastoral districts were re-interpreted based on an assignment of the pastoral land system mapping units to Subregion groupings. As part of that update, the land system mapping units replaced the CSIRO environmental associations as the smallest units maintained for the IBRA framework in SA. These updates were initially featured in an SA-only draft IBRA layer designated Version 6.2. These updates are now fully incorprated in the national IBRA Version 7.0 dataset with some additional updates.
