FENZ consists of a large set of spatial data layers and supporting information on New Zealand's rivers, lakes and wetlands. The database aims to support decision making on freshwater ecosystem and biodiversity management by providing a consistent, robust national dataset for a range of freshwater ecosystems attributes.
The Freshwater Ecosystems of NZ (FENZ) geo-database provides an independent, national representation of the biodiversity values and pressures on New Zealand's rivers, lakes and wetlands. It had its origins in the Waters of National Importance (WONI) component of the Ministry for the Environment's Sustainable Development Programme of Action (2007).
The FENZ database builds a robust, objective picture of New Zealand’s freshwater with the aim of supporting and informing decisions around conservation and freshwater ecosystem management. It represents a whole-of-government approach to the management of New Zealand’s freshwater resources.
FENZ is a large set of spatial data layers and supporting information on New Zealand's rivers, lakes and wetlands. It contains data gathered from a wide variety of sources. It can be used to objectively map and quantify various aspects of New Zealand's freshwater.
It provides a comprehensive descriptions of the physical environment and biological character of freshwater ecosystems and established classifications that group together rivers and streams, lakes and wetlands having similar ecological character.
Data is also provided on estimates of human pressures and impacts on biodiversity status, and rankings of biodiversity value that indicate a minimum set of sites that would provide representative protection of a fullrange of freshwater ecosystems while taking account of both human pressures and connectivity
