Identifying Groundwater Dependent Ecosystems 2009-06-03T02:40:17Z 2009-08-05T23:08:24Z Identifying Groundwater Dependent Ecosystems Professor Derek Eamus Professor Derek Eamus Groundwater dependent ecosystems (GDEs) are important elements in the landscape that require access to groundwater to maintain their health and vigour. They are important because of their conservation, biodiversity, ecological, social and economic value. There are two threats to GDEs — outright loss of habitat and outright loss of groundwater resources. PN30129 PN30129 978-0-9806610-8-8 978-0-9806610-9-5
