The wetland classification codes are a series of letter and number codes that have been developed to adapt the national wetland classification system to map form. These alpha-numeric codes correspond to the classification nomenclature that best describes a particular wetland habitat. For example, PFO1A = Palustrine (P), Forested (FO), Broad-leaved Deciduous (1), Temporarily Flooded (A).
To view full descriptions of wetland codes please visit the Wetlands Mapper. When a wetland polygon is clicked on, the option to view the complete code description is provided. This opens the description tab, which provides users with full details of the classification code for that wetland feature. For more information about wetland codes and the wetland classification system please refer to the documents linked below.
