Archived BioMetric and Threatened Species Profiles datasets

With the commencement of the Biodiversity Conservation Act and Biodiversity Assessment Methodology (BAM) on 25 August 2017 the BioMetric and Threatened Species Profiles (TSP) data sets are evolving. This page provides access to the archived data sets

BioMetric and Threatened Species Profile data sets were originally defined under the Native Vegetation Act 2003 and the Environmental Outcomes Assessment Methodology.

1. Over-cleared vegetation types

'Over-cleared vegetation types', otherwise known as BioMetric vegetation types (BVTs), were a list of vegetation communities that occur within each NSW catchment management authority (CMA) region.

BioMetric Vegetation Types were retired from the VIS Classification system on 21 August 2017, and were replaced with Plant Community Types (PCTs). Reasons for this change include: to simplify the NSW vegetation classification system; to facilitate development of quantitatively plant community types, and seamless state-wide plant community type mapping.

Access archived over-cleared vegetation types data (XLS 1.9MB).

2. Vegetation condition benchmarks

Vegetation condition benchmarks transitioned to a new quantitively derived benchmark system on 21 August 2017.  

Access archived vegetation condition benchmark data (XLS 475KB).

3. Threatened Species Profiles Database

Threatened Species Profiles Database (TSPD) resided as a module in the BioNet-Atlas application up until 21 August 2017. At this point, the name of this module was changed to Threatened Biodiversity Profiles data collection, and a number of core attributes used to calculate biodiversity credits changed.

Access archived TSPD credit calculator data (XLS 486KB).

Access archived TSPD vegetation association data (XLS 3.8MB).

Access archived TSPD response to management data (XLS 514KB).

4. Over-cleared landscapes

Over-cleared landscapes data remains unchanged following the introduction of the Biodiversity Conservation Act 2017 on 25th August 2017.

The over-cleared landscape values comprise the percentage-cleared estimate for each Mitchell Landscape in each catchment management authority area. This data set is framed around a threshold of 70 per cent cleared per landscape. To obtain these estimates, the landscapes were intersected with a presence/absence layer of native vegetation in NSW (Pressey et al. 2000).

The ecosystem classification used for this purpose (Mitchell Landscapes) is mapped at a 1:250,000 scale.  In 2006, the NSW vegetation presence/absence mask was updated and intersected with the Mitchell Landscapes layer to produce revised percentage-cleared estimates for each Mitchell Landscape (see ELA 2007b, c).

In 2008, the Mitchell Landscapes line work was systematically reviewed and revised where necessary, at 1:100 000 scale. See Mitchell Landscapes vs (PDF 11MB).

Access to the most up to date, comprehensive and approved 'over-cleared landscapes' data is via the BioNet Vegetation Classification dataset. Follow the Over-cleared Landscapes Quick Guide (PDF 562KB) to export up-to-date approved landscapes data of interest .

Access the latest NSW Mitchell Landscapes v3.1 layer, which is now maintained with over-cleared landscape values in it.
