Wetlands are important for many plants and wildlife in the ACT, as well as water quality for Canberra's drinking water catchment. This dataset maps location of wetlands in the ACT including our Ramsar wetland (Ginini and Cheyenne Wetland Complex), Directory of Important Wetlands Australia (DIWA), and ACT High Country Bogs and Fens (Nature Conservation Act 2014). The wetlands are classified using the ANAE Australian National Aquatic Ecosystem Framework by Cowood et al (2017). See Brooks (2021) for the latest ANAE classification framework and method. To view the directory of important wetlands visit: https://www.dcceew.gov.au/water/wetlands/australian-wetlands-database/directory-important-wetlands More information on wetland conservation can be found at:https://www.act.gov.au/open/act-aquatic-and-riparian-conservation-strategy Fit for purpose: This dataset was captured at 1:5,000 scale. This dataset is fit for use as a tool for showing presence of wetlands in the ACT. Exact boundaries are likely to expand and contract over time so accuracy should be checked against project requirements.

The focus of this dataset is the Australian Capital Territory (ACT). It contains digital spatial data developed to assist in land management decision making in the ACT. The dataset contains hazard ratings for land salinity, stream salt load and stream EC as well as overall salinity hazard for each HGL unit. Information about landscape functions and appropriate salinity management strategies are also listed. Hyperlinks to full management descriptions for each HGL unit are provided. The Hydrogeological Landscape (HGL) concept provides a structure for understanding how differences in salinity are expressed across the landscape. A HGL spatially differentiates areas with similar salt stores and pathways for salt mobilisation. The process of delineating a HGL relies on the integration of a number of causative factors: geology, soils, slope, regolith thickness, and climate; an understanding of the different modes of salinity development; and the impacts of salinity within landscapes (land salinity, salt load and salt concentration in streams due to salt contributions from base flow and runoff ). Information sources such as soil landscape maps, site characterisation, salinity occurrence maps, hydrogeological data, surface water and groundwater data are incorporated into standardised unit descriptions.Fit for purpose: This dataset was captured at 1:25,000 scale. This dataset is fit for use as a tool for assessing land 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.Credits: Rob Muller (NSW OEH), Wayne Cook (NSW OEH), Allan Nicholson (NSW DPI), Alie Cowood (UC)Disclaimer: While all care is taken to ensure accuracy, the ACT Government does not warrant that the map is free from error.

ACT Climate refugia are core areas of the landscape most likely to support persistence of dominant trees, shrubs and grasses of the Capital Region under climate change.The data identify refugia expected to support climate sensitive species characteristic of each vegetation community, both now and into the future, based on distribution modelling using NARCLiM climate projections (MacKenzie et al 2019).The areas shown (refugia) highlight where the most stressed subset of dominant plant species today (i.e., common trees, shrubs and grasses modelled to lose >= 75% of their current distribution) are more likely to persist under a wide range of future climate scenarios. These refugia can be used to prioritise management actions to minimise further stresses to those communities (e.g. prescribed burning within tolerable fire intervals; climate-adaptive revegetation programs, etc). Note: Areas smaller than 0.5 hectares have been removed to enable quicker map drawing, contact officeofnatureconservation@act.gov.au for the full dataset, including ensemble forecasts for individual plant species (n=151).Source Technical Report:MacKenzie, J.B., G.
