Improving waterway habitat quality and connectivity within priority stream reaches of the Brid, Pipers and Boobyalla catchments to promote the expansion and recovery of Giant Freshwater Lobster (Astacopsis gouldi) populations in north-eastern Tasmania.
The Giant Freshwater Lobster Project will focus on engaging landholders in priority stream reaches to undertake on-ground waterway restoration works and raise awareness of the threats and needs of the Giant Freshwater Lobster. A citizen science monitoring program will be established to collect data to improve knowledge about the species and where to focus investment.
The Giant Tasmanian Freshwater Lobster (Astacopsis gouldi; also called Giant Freshwater Crayfish) is the world’s largest freshwater crustacean and is only found in rivers, lakes and streams in northern Tasmania, with the exception of the Tamar catchment. The species is listed as vulnerable under both the Environment Protection and Conservation Act 1999 and the Threatened Species Protection Act 1995; it is listed as endangered under the IUCN Red List of Threatened Species, and is culturally significant to the Tasmanian Aboriginal community. Threats to the Giant Freshwater Lobster include habitat disturbance or loss, sedimentation of waterways, illegal fishing pressure, drought and climate change. Any form of land clearing or habitat disturbance that results in increased sedimentation of waterways, including in-stream erosion, bank destabilization, slope run-off and clearing in upstream reaches of catchments supporting Giant Freshwater Lobster populations present high risks, particularly for juveniles.
The Giant Freshwater Lobster Project will:
Return to the Biodiversity Program.
Improving land management practices of communities and landholders to increase the vegetation and biodiversity of productive landscapes.
Reducing threats to Hooded Plover breeding success in northern Tasmania.
Supporting small landholders to care for their natural resources.
