There are three wetland datasets for the southern portions of the Midwest, encompassing Cervantes, Jurien Bay, Greenhead, Eneabba and Cataby town sites. Some of these datasets overlap each other.

Geomorphic Wetlands Cervantes Eneabba dataset

This dataset displays the wetland boundaries (extent) and geomorphic wetland classification (type). It covers an area from Cervantes to 7km west of Bangingarra and from 8km north of Coolimba to 15kilometres east of Eneabba.

The western portion of this dataset has been mapped, at a finer scale, in the Geomorphic Wetlands Cervantes Coastal dataset.

Geomorphic Wetlands Cervantes Coastal dataset

This dataset displays detailed wetland boundaries (extent), geomorphic wetland classification (type) and wetland management categories (evaluation). It includes wetland mapping for a 17km wide coastal strip from 6km south of Cervantes to 10km north of Coolimba.

This dataset overlaps portions of the Geomorphic Wetlands Cervantes Eneabba dataset.  

Geomorphic Wetlands Cervantes South dataset

This dataset displays detailed wetland boundary (extent), and geomorphic classification (type). It covers an area between Cervantes and Cataby in the Shire of Dandaragan, on the northern Swan Coastal Plain.  

This dataset adjoins both of the other Midwest datasets.

These three wetland datasets: 

• Geomorphic Wetlands, Cervantes Eneabba dataset (DBCA-015)
• Geomorphic Wetlands Cervantes Coastal dataset (DBCA-014)
• Geomorphic Wetlands, Cervantes South dataset (DBCA-013)

can be downloaded for free via Data WA or viewed via Landgate’s public map viewer Locate.

The methods and resulting wetland mapping and classification for these datasets have been endorsed by the DBCA, the Department of Water and Environmental Regulation, the Wetland Status Working Group and the Wetlands Coordinating Committee.

The South Coast Significant Wetlands dataset displays the location and boundary of known regionally and internationally significant wetlands across an area of the south coast region.

The dataset has been derived from data sources (available from the DBCA Library) including:

• A preliminary evaluation of wetlands in the Esperance water resource region (Ecologia 2000)
• Preliminary delineation of consanguineous wetland suites in the Pallinup - North Stirling region, South Western Australia (V & C Semeniuk Research Group 1999)
• Preliminary delineation of consanguineous wetland suites between Walpole and Fitzgerald Inlet, Southern Western Australia (V & C Semeniuk Research Group 1998) reports

This dataset overlaps the Walpole Wilderness Peat Wetlands.

The South Coast Significant Wetlands dataset (DBCA-018) can be downloaded free via the WA government data portal or viewed via Landgate’s public map viewer Locate.

The Geomorphic Wetlands Swan Coastal Plain dataset displays attributes including wetland boundary (extent), classification (type) and management categories (evaluation). If covers portions of the Swan Coastal Plain between Wedge Island and Dunsborough.

This dataset adjoins and overlaps some wetland datasets in the Wheatbelt and South West

The dataset was originally digitised from the 1996 report, Wetlands of the Swan Coastal Plain Volume 2B Wetland Mapping, Classification and Evaluation: Wetland Atlas (Hill et al.). As custodian, the department has regularly made changes to the dataset to reflect changes to wetlands. This dataset is often available with two versions of symbology, one for wetland classification and another for wetland management category. The underlying dataset is the same.

This dataset was endorsed by the Wetlands Coordinating Committee, the Environmental Protection Authority, and the Department for Planning and Infrastructure.

The Geomorphic Wetlands Swan Coastal Plain dataset (DBCA-019) can be downloaded free via the WA government data portal or viewed via Landgate’s public map viewer Locate.

There are five separate wetland datasets available for the South West of Western Australia.  They cover portions of an area, west of a line from Donnybrook to Nannup to Manjimup to Denmark. Many of these datasets adjoin, and/or overlap each other.

Geomorphic Wetlands Augusta to Walpole dataset

This dataset displays the wetland boundary (extent), and geomorphic classification (type). This dataset covers two areas one along the southern coast from August to Lake Jasper and a second area along the coast from of Northcliffe to Walpole with a spur heading north from Walpole.

This dataset adjoins or overlaps all of the other South West datasets.

The dataset was originally digitised from the 1997 report, Mapping and classification of wetlands from Augusta to Walpole in the South West of Western Australia (V & C Semeniuk Research Group) available from the DBCA Library.

Geomorphic Wetlands South West dataset

This dataset displays wetland boundaries (extent), classification (type), and wetland management categories (evaluation) This dataset covers an area west of a line from Marybrook to Witchcliffe out to Wonnerup.

This dataset adjoins the Geomorphic Wetland Swan Coastal Plain and Geomorphic Wetlands Leeuwin Naturaliste Ridge and Donnybrook to Nannup datasets and overlaps Geomorphic Wetlands Augusta to Walpole dataset.

Geomorphic Wetlands Leeuwin Naturaliste Ridge and Donnybrook to Nannup dataset

The dataset displays wetland boundaries (extent) and classification (type). This dataset covers two separate areas. One along the coast between Cape Naturaliste and Augusta and a second area east of the Geomorphic Wetlands South West dataset from 9km north of Donnybrook to 15km south of Nannup.

This dataset adjoins the Geomorphic Wetland South West dataset and overlaps Geomorphic Wetlands Swan Coastal Plain and Geomorphic Wetland Augusta to Walpole datasets.

Geomorphic Wetlands Manjimup to Northcliffe dataset

This dataset displays wetland boundaries (extent) and classification (type). This dataset covers an area from the western side of a line from Manjimup to Northcliffe to 5km west of Lake Jasper.

This dataset adjoins the Geomorphic Wetlands Augusta to Walpole dataset to the south and west.

Walpole Wilderness Peat Wetlands dataset

This dataset displays the location, boundary (extent) and landform or classification of wetlands and areas of organic soils within Walpole Wilderness area. The current dataset isolates flat systems from surrounding upland areas and provides a preliminary classification of wetlands. This data will support wetland management and aid in fire suppression in the peatland areas.

This dataset is overlapped by the South Coast Significant Wetlands dataset and adjoins the Geomorphic Wetlands Augusta to Walpole dataset.

Geomorphic Wetlands South West, Geomorphic Wetlands Leeuwin Naturaliste Ridge and Donnybrook to Nannup and Geomorphic Wetlands Manjimup to Northcliffe dataset mapping projects were managed by DBCA and funded by South West NRM (formally South West Catchment Council). They have substantially increased the area of available wetland mapping in an area which is subject to significant development pressures.

These datasets have not undergone a review process, where errors are identified, advice can be sought from the DBCA.

These four wetland datasets:

• Geomorphic Wetlands South West – Unreviewed (DBCA-040)
• Geomorphic Wetlands Leeuwin Naturaliste Ridge and Donnybrook to Nannup – Unreviewed (DBCA 043)
• Geomorphic Wetlands Manjimup to Northcliffe – Unreviewed (DBCA-044) and
• Walpole Wilderness Peat Wetlands - Unreviewed (DBCA-042)

can be downloaded free via the WA government data portal or viewed via Landgate’s public map viewer Locate.

There are three wetland datasets that cover portions of the wheatbelt region.

Wheatbelt Wetlands Stage 1 dataset

This dataset displays the wetland boundaries (extent) within the Wheatbelt region of south-west Western Australia, as well as in a small area of the Rangelands to the east and the Darling Scarp to the west.

This dataset adjoins a small portion of Geomorphic Wetlands Swan Coastal Plain dataset.

Wheatbelt basin and granite outcrop wetland evaluations dataset

The dataset is a point based dataset which provides additional data to the Wheatbelt Wetlands Stage 1 dataset. It displays the conservation significance assigned to basin and granite outcrop wetlands. This dataset covers the same area as the Stage 1 dataset.

Geomorphic Wetlands Darkan-Duranillin Stage 2 dataset

Thes dataset displays wetland boundary (extent), and geomorphic classification (type) within an area of about 150,000 hectares near Duranillin in the Shire of West Arthur, in the Wheatbelt region. The dataset identifies 895 wetlands, covering about 19 per cent of the 150,000 hectare project area.

The two wetland boundaries datasets: 

• Wheatbelt Wetlands Stage 1 dataset (DBCA-021) 
• Geomorphic Wetlands, Darkan Duranillin dataset (DBCA-016) 

 can be downloaded free via the WA government data portal or viewed via Landgate’s public map viewer Locate. The Wheatbelt basin and granite outcrop wetland evaluations dataset is not publicly available can be requested from wetlands@dbca.wa.gov.au.

The methods and resulting datasets have been endorsed by DBCA, the Wetland Status Working Group and the Wetlands Coordinating Committee.  The Darkan-Duranillin dataset was also endorsed by the Department of Water.

Broad scale wetland mapping projects have been conducted in various parts of the State.

These older studies have been published in report form rather than in digital datasets and are available from the DBCA Library.
