Tasmanian Estuaries (North West) Marine Habitats - 1:25000

The Tasmanian Estuaries (North West) Marine Habitats 1:25,000 layer depicts marine habitats of four estuaries (Montagu River, Duck Bay, Black River and Detention River). The habitat types depicted in the dataset include rocky reef, sand, hard sand and seagrass. The data was collected in April 2005 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The shallow waters of the estuaries enabled the use of aerial photography imagery as the primary data source. The habitats defined in the imagery required thorough checking in the field via underwater camera equipment, echo sounder data, and a Differential GPS unit to enable field checking of the image interpretation. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995 and to support Natural Resource management priorities in the Cradle Coast NRM region of Tasmania.
