Description: The Geomorphic Wetlands Cervantes Coolimba Coastal Stage 2 dataset displays the location, boundary and geomorphic classification and Stage 2 management categories of wetlands. The dataset covers a coastal area within the Shires of Dandaragan, Coorow & Carnamah on the Midwest coast of Western Australia. It is partially on the Swan Coastal Plain and partially on the Geraldton Sandplains, in the vicinity of Cervantes, Jurien Bay, Greenhead and Leeman town sites. The project area is approximately 100,000 ha (excludes oceanic area).There are three components to the project:1.Wetland desktop mapping with limited on-ground confirmation (identification of wetlands, boundary delineation of wetlands and classification of wetland using the geomorphic wetlands classification system)2.Wetland desktop evaluation (Stage 2 wetland management categories)3.Methodology for deriving a wetland management category for environmental impact assessment using desktop and on-ground information (Stage 3 wetland management categories)Wetlands in this dataset have been classified into types according to the geomorphic wetland classification system (Semeniuk 1987, Semeniuk & Semeniuk 1995). In addition to the self-emergent wetlands, springs, estuary-peripheral and estuary type wetlands. The geomorphic classification system defines wetlands based on their landform and water permanence.Beaches, wetlands on offshore islands, subterranean and artificial wetlands were not included in the scope of the project.Wetlands have been assessed for their conservation significance and assigned a Stage 2 management category (Conservation, Rehabilitation Potential and Multiple Use) using desktop evaluation techniques and set criteria.Detailed methodology and results are described in the wetland mapping report: Wetland identification, delineation and classification: Results for the Geomorphic Wetlands Cervantes Coolimba Coastal Stage 2 dataset (Shanahan/DEC 2012) and the applied evaluation report: Wetland evaluation: Stage 2 results for the Geomorphic Wetlands Cervantes Coolimba Coastal Stage 2 dataset (Shanahan/DEC 2012)A total of 315 wetlands are mapped in the dataset comprising of 21,280 ha of mapped wetland extent (approximately 21% of total project area). The number of wetlands mapped, by type, plus the relevant percentage is as follows:Lake 2 (9.82%)Sumpland 113 (20.6%)Playa 54 (8.27%)Dampland 29 (6.29%)Floodplain 8 (0.21%)Barlkarra 18 (19.76%)Palusplain 35 (25.34%)Paluslope 11 (2.67%)River 3 (0.86%)Creek 12 (1.34%)Wadi 17 (1.16%)Estuary 1 (0.01%)Estuary-peripheral 3 (0.7%)Self-emergent wetland 2 (2.53%)Spring 7 (1.25%)73% of wetlands in the project area are assigned a Stage 2 management category of Conservation, 0.5% are Rehabilitation Potential and 25% are Multiple Use.Significant wetlands identified are as follow:• Salt lakes from Jurien Bay to Coolimba including Leeman Lagoon and Eatha Claypan• Springs connected to salt lakes including Eatha Spring, Diamond of the Desert Spring and Thetis Claypan springs. • Large sumpland to the east of Leeman Lagoon (UFI269; Shanahan Sumpland)• Other springs and self-emergent wetlands including Roman Forte wetland, Little Three Springs and South Little Three Springs• Hill River and Hill River Estuary• Lake Logue / Indoon system• Cockleshell Gully• Lake Thetis
