Biodiversity planning assessments

Figure 1 Current BPAs

A Biodiversity Planning Assessment (BPA) identifies the terrestrial ecological values in a region, or bioregion, according to their conservation significance. BPAs are used by governments, members of the community and landholders to make planning decisions about appropriate land use.

The final BPA, which contains a spatial dataset, expert panel report and summary report (where available), can be accessed using the Queensland Spatial Catalogue website.
(Note: the BPA is a non-social and non-economic assessment, and is produced without regard to land tenure).

A report summarising selected terrestrial and aquatic conservation values as identified by current biodiversity planning assessments and aquatic conservation assessments for a specific location, can be generated through Environmental reports online.

BPAs have been released for approximately 80% of Queensland and these assessments are listed in the table below.

Biodiversity Assessment and Mapping Methodology

The Biodiversity Assessment and Mapping Methodology (BAMM) (PDF, 700KB) is a scientific methodology that provides a consistent approach for assessing biodiversity values at the landscape scale in Queensland. It is the methodology used to generate BPAs for each of Queensland’s bioregions and has been used for ecological values assessment since 2001.

The base layer for analysis is the regional ecosystem mapping from the Queensland Herbarium and the method incorporates a range of biodiversity related data. The BAMM is focused primarily on assessing terrestrial values. Whilst the BAMM includes some wetland values, AquaBAMM provides specific and more detailed information on wetlands values.

The BAMM is applied in two stages. The first stage uses existing data to assess ecological concepts such as rarity, diversity, fragmentation, habitat condition, resilience, threats, and ecosystem processes in a uniform and reliable way across a bioregion. These criteria are used to filter available data and provide an initial determination of significance. This initial assessment is generated through GIS.

The second stage uses expert knowledge to identify features such as wildlife corridors and areas with special biodiversity value (e.g. centres of endemism or wildlife refugia), and includes data that may not be available uniformly across the bioregion. The overall biodiversity significance is a combination of the first and second stage values.
