Quick facts

National Groundwater Dependent Ecosystems Atlas
The National Groundwater Dependent Ecosystems Atlas combines nationwide layers of satellite remote sensing data with existing mapping and literature. Queensland’s GDE mapping is produced at a finer scale than the National GDE Atlas, typically 1:100,000 or 1:50,000 scale.

In partnership with other programs, the wetland mapping has been enhanced by the mapping of Groundwater Dependent Ecosystems (GDEs). GDEs are ecosystems which require access to groundwater on a permanent or intermittent basis to meet all or some of their water requirements and include aquifers, springs, caves, lakes, palustrine wetlands, rivers and terrestrial ecosystems. A GDE mapping and classification methodology has been developed and is being applied to generate mapping for Queensland. The mapping is supported by a suite of pictorial conceptual models of different GDE types, a set of mapping rule sets and Frequently Asked Questions and handbooks.

Groundwater dependent ecosystems (GDEs) mapping

Queensland’s GDE mapping builds on existing information, including wetland mapping, regional ecosystem mapping, a spring and small waterholes database, and drainage lines. This information is combined with feedback from a broad range of experts[1]. Only some parts of Queensland have been mapped (see map).

The Queensland GDE mapping consists of 5 data sets which need to be combined to show all GDEs.

Wetland on-line education modules

A series of on-line education modules have been prepared as a resource for people who want to learn more about wetlands. You can use these to meet your learning and training needs. This information should be used in conjunction with information found on this website.
