ACT_Wetlands_Nov_2016

Abstract

This product is the result of wetland mapping, classification and an assessment of climate change impacts on wetlands in the ACT to determine their climate change vulnerability. It comprises two datasets: the classification (HGL_ACT_Wetland_Class_Nov_2016) and the assessment (HGL_ACT_Wetland_Assess_Nov_2016). The assessment uses the management areas developed in the ACT HGL framework project as planning units (Cowood et al. 2016 - Expansion of landscape characterisation methods within the Hydrogeological Landscape Framework: application in the Australian Capital Territory). Mapping of management areas allows for detailed hazard assessments to understand the patterns in the chosen variables, facilitating management within the HGL framework and consideration of landscape setting when identifying suitable locations to undertake management actions.

The wetland mapping is a compilation of existing spatial layers and API validation, with classification as per the Australian National Aquatic Ecosystem Framework (AETG 2012). The wetland assessment uses the current (1990-2009) and near future (2020-2039) time periods from the NARCliM Project (Olson et al. 2014 - NARCliM Climatological Atlas. NARCliM Technical Note 4), but individually assesses consensus, wet-cool extreme and dry-hot extreme scenarios. Variables used in this assessment represent indicators of current anthropogenic pressure, future hydrological change in water sources and losses and future ecological change in vascular plant and amphibian communities. Statistical methods are used to group wetlands that are projected to experience similar levels of change in the future determining their climate change vulnerability and the principle components of change driving the variability. The variables are first attributed to the management areas across the ACT and then allocated to wetlands located within each management area. Hydrological change variables were refined for individual wetlands considering the unique water balance equations.

Purpose

This data package was generated for the ACT Environment and Planning Directorate as a component of the ACT Hydrogeological Landscapes (HGL) Framework project. The focus of this project was to assess impacts of climate change on wetlands and on land degradation issues related to salinity and erosion in the ACT.

Lineage

The wetland mapping and classification for the ACT used spatial data from ACT Environment and Planning Directorate and NSW Office of Environment and Heritage corporate data sets as stated in the associated ACT wetland mapping, classification and condition reporting (Cowood 2015 - ACT wetland mapping, classification and assessment of hydrological vulnerability; and Cowood et al. 2017 - Wetland vulnerability to climate change in the ACT).

Reporting was updated to represent the outputs of Stage 2 in December 2015.

DQ Topological Consistency

Effective date

2016-11-05

Explanation

All polygons in the coverage are topologically correct and all polygons have been attributed. Data has been visually checked at applicable scales.

DQ Absolute External Positional Accuracy

Effective date

2016-11-05

Explanation

The accuracy of the polygons has been checked against 10cm aerial photography flown in 2012 which was supplied by the ACT Environment and Planning Directorate.

DQ Non Quantitative Attribute Correctness

Effective date

2016-11-05

Explanation

All polygons are labelled with wetland classification and condition attributes as stated in Appendix 2 of the associated ACT wetland mapping, classification and condition reporting (Cowood 2015 - ACT wetland mapping, classification and assessment of hydrological vulnerability; and Cowood et al. 2017 - Wetland vulnerability to climate change in the ACT). Attributes were checked as part of routine GIS capture quality assurance procedures, including a visual check of polygon tags against aerial photography.
