PCTs are the finest level in the NSW vegetation classification hierarchy. They identify and describe recurring patterns of native plant species assemblages in relation to environmental conditions (soil, temperature, moisture and other factors). The floristic composition of PCTs is characterised by frequently co-occurring species, including combinations of trees, shrubs and/or ground cover plants.
PCTs play a central role in the NSW Biodiversity Offsets Scheme. Assessments of biodiversity values hinge on the identification of PCTs when using the Biodiversity Assessment Method (BAM).
PCTs are defined and mapped across NSW. PCT data are managed as part of the Integrated BioNet Vegetation Data (IBVD) program.
- Revised PCTs for eastern NSW (coast and tablelands bioregions) are now publicly available, and are included in the NSW State Vegetation Type Map.
- Information is available about the Introduction of revised Plant Community Types in eastern NSW to the Biodiversity Offsets Scheme.
- The Plot to PCT Assignment Tool is available, making it easier to identify the correct PCT using standard floristic survey plot data in eastern NSW.
