A wetland is a land area that is saturated with water, either permanently or seasonally. Primarily, the factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation that is adapted to its unique soil conditions.

The water found in wetlands can be saltwater, freshwater, or brackish. Main wetland types include swamps, marshes, bogs and fens. Sub-types include mangrove, carr, pocosin, and varzea.

See Wikipedia wetland on Wikipedia

Wetlands are also typically found at the fringes of rivers, lakes or along the coastline.

How to map

ElementArea.png Add natural=wetland to an area.

Use wetland=* to describe the type of wetland.

Other useful generic tags :

  • tidal=yes/no Indicates if the wetland is subject to temporary inundation based on the tide.
  • managed=* indicates if the wetland is managed in any form.
  • seasonal=* indicates if the wetland is seasonal.
  • ramsar=yes indicates if it is a Ramsar site.
