Conservation of Freshwater Ecosystem Values (CFEV) Assessment Framework
Description and method logic
The purpose of the CFEV assessment is to identify important freshwater values.
The Conservation of Freshwater Ecosystem Values Project (CFEV) developed an assessment framework as part of the Water Development Plan for Tasmania. The CFEV assessment identifies high priority freshwater values are appropriately considered in the development, conservation and management of Tasmania's water resources.
The design of the CFEV assessment framework is based on Comprehensive, Adequate and Representative (CAR) principles and also includes the condition of the catchment. It complements the terrestrial and marine management systems already in place in Tasmania.
The assessment uses existing environmental data to identify the freshwater values for rivers, water bodies, wetlands, saltmarshes, estuaries, groundwater dependent ecosystems and karst systems and combined with other data relating to special values, to provide a conservation value. All freshwater-dependent areas throughout Tasmania can be identified with a conservation management priority score of low, medium, high or very high priority.
A GIS database stores the assessment results and can be used to produce reports for any freshwater related area of the State.
Criteria groupings of the method
Criteria are based on Comprehensive, Adequate and Representative (CAR) reserve design principles, as well as Naturalness, Representativeness and Distinctiveness (NRD).
State wide datasets including:
Expert panels, GIS experts and database management.
A database platform for data storage, manipulation and values assessment, a Geographic Information System (GIS) platform for result presentation and interpretation.
Conservation/priority values for wetland ecosystems in Tasmania:
Criteria by category
Physical and chemical
Management and planning
The method is best by government agencies.
Tasmania's water management and conservation authorities use the CFEV database to help them assess the ecological sustainability of future water related developments, to protect significant freshwater values, and to assist in focussing freshwater management efforts to protect and/or restore high conservation value ecosystems.
