Description: The Geomorphic Wetlands Cervantes Eneabba Stage 1 dataset displays the location, boundary and geomorphic classification of wetlands. The majority of wetlands in this dataset have been classified into types according to the geomorphic wetland classification system (Semeniuk & Semeniuk 1995 and unpublished report to the Department of Environment and Conservation (DEC 2007; VCSRG 2006). This classification system defines wetlands based on their landform and water permanence. Channel type wetlands (rivers, creeks, troughs and wadis), beaches, wetlands on offshore islands, subterranean and artificial wetlands were not included in the scope of the project. The Geomorphic Wetlands Cervantes Eneabba Stage 1 dataset is 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, Eneabba and Badgingarra town sites. The project area is approximately 360,000 ha (excludes oceanic area). The original mapping was conducted by V & C Semeniuk Research Group (VCSRG) in 2006 using information sources such as hard copy 1:25,000 stereoscopic aerial photographs and topographic maps. Wetland boundaries were traced by superimposing transparent sheets (overlays) on top of 1:50,000 orthophotos. A limited amount of wetlands were visited in the field by VCSRG to groundtruth desktop outputs. The wetlands depicted on these overlays were then digitised by Department of Water (DoW) to produce a draft dataset in 2006 (DoW 2006). The original mapping project was funded by the Natural Heritage Trust. In 2010 the draft dataset was reviewed by DEC and DoW to ensure it accurately reflected information depicted on the VCSRG overlays. The resulting product was a revised dataset named the Geomorphic Wetlands Cervantes Eneabba Stage 1 dataset (DEC 2010). DEC Wetlands Section managed the review project and the development of the final dataset with funding from DoW through the National Water Commission's Groundwater Action Plan Fund. The original project evaluated (assessed the values) of wetlands in the project area, however, the evaluation methodology and data was not included in the review and it is not an attribute of this dataset. A total of 458 wetlands are mapped in the dataset comprising of 16,594 ha of mapped wetland extent (approximately 4.6% of total project area). The number of wetlands mapped, by type, plus the relevant percentage is as follows: dampland 131 (28.6%); sumpland 112 (24.4%); playa 83 (18.1%); palusplain 31 (6.7%); Paluslope 29 (6.3%); barlkarra 26 (5.6); not classified 32 (5.8%); floodplain 12 (2.6%); and lake 2 (0.4%).
