This layer provides a spatial representation of freshwater ecosystem values that are key values in each reserve in the National Reserve System in Tasmania. Karst, saltmarshes and estuaries are included in this metadata statement.

This layer provides a spatial representation of the threatened and significant vegetation communities that are key values in each reserve of the National Reserve System in Tasmania.

This layer provides a spatial representation of threatened fauna species that are key values in each reserve of the National Reserve System in Tasmania. Those species that were analysed by using Range Boundaries are included in this metadata statement.

This layer provides a spatial representation of threatened fauna species that are key values in each reserve of the National Reserve System in Tasmania. Those species that were analysed by buffering the observation records, including nests, are included in this metadata statement.

This layer provides a spatial representation of the threatened and priority plant species that are key values in each reserve of the National Reserve System in Tasmania.

The CFEV Wetlands data layer shows a statewide coverage of wetlands in Tasmania. Individual features (wetlands, marshes) are rated according to their overall conservation value (relative to other wetlands), as assessed by the Conservation of Freshwater Ecosystem Values (CFEV) Program. The data also includes an assessment of condition and conservation management priority for each wetland feature.

The CFEV Groundwater Dependent Ecosystems (GDEs) data layer shows generalised point locations of known freshwater-dependent ecosystems highly dependent on groundwater across Tasmania. This layer mainly includes various types of springs. Conservation rankings for karst are not included in this layer and are provided separately in the CFEV Karst data set.

A collection of Integrated High Ecological Value assets that form the natural hydrological grid across 34 Local Government Areas within the Greater Sydney Region. This data has been prepared by the Science Division of DPIE (former OEH), with input layers and support for the map provided by the NSW Department of Primary Industries-Fisheries and Department of Industry-Crown Lands and Water. Similar mapping has been prepared by OEH for the Land Use and Infrastructure Implementation Plans for the Wilton (Wilton2040, page 22) and Greater Macarthur (interim plan, page 36) Priority Growth Areas. These data packages were specifically developed for input to Local Government Local Strategic Planning Statements to support Council’s delivery of Strategy 25.1 of the Greater Sydney Region Plan. The map shows areas where waterways and water dependent ecosystems are defined as high ecological value, based on definitions, guidelines and policies under the Environment Protection and Biodiversity Conservation Act 1999, Biodiversity Conservation Act 2016, Fisheries Management Act 1994 and Water Management Act 2000. Water dependent ecosystems are defined as wetlands, and flora and fauna that rely on water sources (including groundwater). The map represents an overlay of 39 indicators being used by the State Government to define high value water dependent assets. The method used to derive the integrated layer is similar to mapping produced for the draft Cumberland Plain Conservation Plan. The purpose of the map is to identify strategic planning priorities for protecting and improving the health of high value waterways and water dependent ecosystems in the Greater Sydney Region LGAs. Once identified, the priorities can be used as a basis for identifying aquatic biodiversity refugia, stream rehabilitation efforts and setting management targets and/or land use planning controls that would protect or improve the health of waterways and water dependent ecosystems so they provide the essential services and functions expected of a cool blue-green corridor. The datasets were created by initially placing a 1-hectare hexagon grid over the relevant boundary area and attributing the grid with either ‘Absent’ or ‘Present’. This represents an occurrence only of high value water dependent ecosystems layers within the hexagon grid. The ‘HEVlyr’ field provides a count of the number of layers within the hexagon. A value of zero (0) represents Absent, values of greater and equal to one (1) represents the Presence of high ecological value assets. The values DONOT indicate the significance of the area, i.e., a value of 1 is no less significant to a higher value. Where layers are Present, please contact data steward for details relating to the underpinning datasets.

The CFEV Estuaries data layer shows a statewide coverage of estuaries in Tasmania. Individual features (estuaries) are rated according to their overall conservation value (relative to other estuaries), as assessed by the Conservation of Freshwater Ecosystem Values (CFEV) Program. The data also includes an assessment of condition and conservation management priority for each estuary.

This is a thematic dataset of high ecological value waterways and water dependent ecosystems for the Wianamatta-South Creek catchment. It brings together 24 indicators being used by the State Government to define high ecological value based on definitions, guidelines and policies under the Environment Protection and Biodiversity Conservation Act 1999, Biodiversity Conservation Act 2016, Fisheries Management Act 1994 and Water Management Act 2000. An additional 11 indicators were included to recognise known community environmental values and uses of waterways and water dependent ecosystems in the area. The water dependent ecosystems consist of wetlands, and vegetation and fauna that rely on surface or groundwater water sources. The purpose of the dataset is to identify strategic planning priorities for protecting and improving the health of high ecological value waterways and water dependent ecosystems, which have been recognised as the natural blue grid in strategic land use planning for the Western Parkland City. The priorities can be used as a basis for identifying aquatic biodiversity refugia, stream rehabilitation efforts and setting management targets and/or land use planning controls that would protect or improve the health of the waterways and water dependent ecosystems. The overall accuracy of the dataset is > 80%, when compared to an independent validation dataset (396 validation sites) made up of field survey data, independent desktop analyses of sites, and the use of existing field survey datasets collated from the BioNet Vegetation Survey database, Blacktown City Council and the Conservation and Sustainability Branch of the Department of Planning and Environment. A technical report* and the accompanying attributes table provides a description of the how the dataset was created and the attributes of the dataset, respectively. *DPE (2022) Mapping the natural blue grid elements of Wianamatta – South Creek: High ecological value waterways, riparian vegetation communities and other water dependent ecosystems.
