Compilation map of existing wetland mapping sourced from the ACT Environment and Planning Directorate and NSW Office of Environment and Heritage. Wetland polygons are classified according to the Australian National Aquatic Ecosystems classification (Aquatic Ecosystems Task Group 2012 - Aquatic Ecosystems Toolkit. Module 2. Interim Australian National Aquatic Ecosystem Classification Framework), using the methodology of Brooks et al. (2014) - Murray-Darling Basin aquatic ecosystem classification: Stage 2 report, and the classification of Claus et al. (2011) - Assessing the extent and condition of wetlands in NSW: Supporting report A – Conceptual framework. Wetlands have been linked to the ACT Hydrogeological Landscape units and Management Areas, with designation as a priority if listed under either Ramsar or Directory of Important Wetland Australia (Environment Australia 2001) or associated with the endangered Alpine Sphagnum Bogs and Associated Fens ecological community (DEWHA 2009).

wb_equation - water balance equation where P denotes precipitation, SR surface runoff, SF flow from a river or stream connection and GW groundwater recharge and discharge, ET evapotranspiration.

w_loss - water loss equation - ET evapotranspiration, SRc surface runoff, SFmi / SFma surface flow, GW groundwater

Updates: The dataset is now static, but can be updated as required if new or better mapping become available.

Fit for purpose: This dataset was captured at 1:25,000 scale. This dataset is fit for use as a tool for assessing wetland management issues at the paddock-scale in the ACT, but this does not negate the need for site assessment at a scale suitable to any potential land use or development under consideration. The mapping was mapped in GDA1994 MGA Zone 55s and transformed to GDA2020 MGA Zone 55s.
