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 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.

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 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.

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

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.
