Mapper Legend

Wetland types are displayed on the Wetlands Mapper in groups of similar classifications (e.g. all freshwater emergent wetlands are displayed as a single color category). The display categories are shown in the table below. Display color codes are provided for those looking to create their own maps using the Mapper color scheme. GIS users can download this layer file that includes the mapper symbology. For instructions on how to add this file to your desktop environment please visit our FAQ page. Wetlands descriptions, definitions and codes are explained further on our Wetland Codes page.
