Data Quality
This dataset is indicative of our current knowledge of the extent of saltmarshes globally based on the data obtained through the inventory, and is not intended to reflect a comprehensive assessment of saltmarsh presence and absence. The dataset is not suitable for temporal analyses of change. Please ensure that the time frames of data collection (noted within the dataset) are suitable for analytical purposes. All spatial analyses should be conducted using the polygon layer distributed in this dataset. The point layer is included for reference purposes only, with useful information regarding wetlands of international importance designated under the Ramsar Convention and site-specific species information (linked to the accompanying Access database through the 'LOCRECID' field). Although mangrove data are not included in the dataset, mangrove habitat may be found in very close proximity to saltmarsh habitat in subtropical and tropical regions. The dataset may contain other habitat types such as freshwater marshes, mudflats and salt plains due to varying collection and mapping methodologies. Source-specific definitions of ‘saltmarsh,’ where available, are included in the accompanying “WCMC027_Metadata_v4” table and Excel spreadsheet ("Habitat translation"). IMPORTANT: As the dataset contains overlapping polygons, a dissolve operation (within GIS) is required before calculating area of extent.
Supplemental Information

The dataset consists of one polygon layer, one point layer, and an accompanying
Access database that contains species information (linked exclusively to the...
