Riverine ecosystems and wetlands
Riverine ecosystems range from uplands through rocky gorges to lowland floodplains. They are often quite different to neighbouring countryside with distinctive habitats, plants and animals.
Riparian zones provide connectivity for migrating birds, as well as habitat and recreational values.
Wetlands provide environmental (e.g. biodiversity, habitat and ecological functions), social and economic values. ACT wetlands are under threat and continued monitoring and maintenance is required.
Two ACT wetlands have a plan of management – Jerrabombera has one through its status as a nature reserve; Ginini has one through its Ramsar listing. Updated planning expectations for Ramsar sites require ‘ecological characteristics’ to be sought for all sites.
Several wetlands projects have been funded including for rehabilitation works and pig control.
Achievement of this target will ensure long-term protection of internationally and nationally designated wetlands and integrity of ACT riparian ecosystems.
The Directory of Important Wetlands in Australia (EA 2001, third edition) lists 13 nationally important wetlands in the ACT (including Jerrabomberra). It includes one Ramsar site (Ginini and Cheyenne Flats). Only two are lowland wetlands, 10 are in Namadgi National Park.
The listing excludes the lakes – Burley-Griffin, Tuggeranong and Ginninderra – and associated ponds.
The ACT also has a large number of farm dams, many of which have considerable biodiversity value.
WORKING WATERWAYS
Creative ways of improving stream health with wetlands, native vegetation and improved management
Working waterways projects include control of riparian weeds and revegetation along the Molonglo, and a survey of vegetation and habitat in key riparian areas.
