The Conservation of Freshwater Ecosystem Values (CFEV) (pronounced "see-fev") program is an initiative of the Department of Primary Industries, Parks, Water and Environment (DPIPWE). Its aim is to ensure that priority freshwater values are appropriately considered in the development, management and conservation of the state's water resources. The program has undertaken an assessment of the conservation management priorities (CMP) of all freshwater ecosystems throughout the state. Through its comprehensive audit of the state's freshwater ecosystems, the CFEV program offers the first Comprehensive, Adequate and Representative (CAR) assessment of freshwater ecosystems conducted in Australia. This data is provided to support the Australian Maritime Safety Authority’s Oil Spill Response Atlas (OSRA) project.

The CFEV Waterbodies data layer shows a statewide coverage of lakes and waterbodies in Tasmania. Individual features (lakes and waterbodies) are rated according to their overall conservation value (relative to other waterbodies), 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 waterbody.

The CFEV Catchments data layer shows the boundaries of catchment boundaries within the major drainage catchments in Tasmania. It is part of a set of nested catchments for the state which reduce in size from the major catchments to sub-catchments to fine-scale river section catchments.

The CFEV River Section Catchments (RSCs) data layer shows 1:25,000 scale catchment boundaries within the major drainage catchments in Tasmania. It is part of a set of nested catchments for the state which reduce in size from the major catchments to sub-catchments to fine-scale river section catchments.

A map of the high ecological value waterways and water dependent ecosystems for the Strathfield LGA was prepared by the Science Division of the Department of Planning, Industry and Environment, with input layers and support for the map provided by the former NSW Department of Primary Industries-Fisheries and Department of Industry-Crown Lands and Water. The basis for the map arises from Science Division inputs to strategic planning processes. For example, the map has been included in the Land Use and Infrastructure Implementation Plans for the Wilton (Wilton2040, page 22) and Greater Macarthur (interim plan, page 36) Priority Growth Areas. This map was 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, however, not all 39 indicators will be present in any one LGA (see Attachment 1 below). For example, there are 9 indicators making up the map for the Strathfield LGA. It should also be noted that the individual indicators have not been ground-truthed and it is recommended that field assessments and/or a comparison to local mapping be undertaken prior to any decisions being made. The map was created by initially placing a 1 ha (to correspond with a lot size) hexagon grid over the LGA, and attributing the grid with the area, length and/or frequency of occurrence of high value water dependent ecosystems. 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 LGA. 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.
