Clearing the waters on GDE management
Groundwater dependent ecosystems (GDEs) require access to groundwater to meet all or some of their water requirements so as to maintain the communities of plants and animals, ecological processes they support, and ecosystem services they provide. GDEs may include rivers, estuaries, springs, wetlands, lakes, terrestrial vegetation, and cave and aquifer systems.
Despite their ecological importance and value, GDEs have been historically poorly understood, with much of our understanding of these ecosystems coming only in the past ten years. Given the considerable threat posed by groundwater extraction, changing mining and landuse practices (particularly urban development) and climate change, it is vitally important that we build our understanding of these ecosystems to ensure they are managed sustainably.
In this seminar, we heard from two of the leaders in GDE science and management in south eastern Australia, and learnt about some of the history of the field, the current state of the practice and future directions. The seminar will included presentations from:
Sarah Gaskill, Senior Environmental Water Planner, Melbourne Water
Dr Jon Fawcett, Practice Leader for GDEs, Jacobs
