IMPROVING HABITAT FOR THE GIANT FRESHWATER CRAYFISH
Cradle Coast Authority is currently managing a project which engages agricultural landholders in six priority areas in actions that improve the river environment for the threatened and uniquely Tasmanian, Giant Freshwater Crayfish. To date, nineteen landholders have entered into management agreements or conservation covenants which will improve their riverine environment. Planned works include fencing along riverbanks to prevent stock access and in many cases prevent bank erosion, off-stream watering points and revegetation to introduce a variety of native plants, including deep-rooting species, on the tops of banks and as understorey layers. Four kilometres of riverbank has already been fenced, with more planned over the drier summer months. Maintaining fallen timber and reintroducing vegetation is important for the survival of the Giant Freshwater Crayfish, as well as freshwater fish and species such as platypus and the burrowing crayfish. The Giant Freshwater Crayfish rely on timber for food and the shading effect from streamside vegetation provides important habitat. Vegetation and adequate vegetated buffers along both banks of the river also provide good filtration strips for any runoff of nutrients and sediment from productive land or from roads and tracks. For more information on the project or species contact Fiona Marshall - Agriculture Project Coordinator fmarshall@cradlecoast.com This project is supported by Cradle Coast Authority with funding from the Australian Government’s National Landcare Program.
