    Fens are a type of wetland. Wetlands are ecosystems where the water table is at or near the ground surface for most of the growing season on most years, and as a consequence, the substrate is poorly aerated, and inundation or saturation last long enough that the dominant plants are those that can exist in wet and reducing conditions.

    What are the biogeochemical characteristics of fens?
    As a type of wetland, fens share many biogeochemical characteristics with other wetlands. Like all wetlands, they play an important role in nutrient cycling because they are located at the interface of aerobic (oxic) and anaerobic (anoxic) environments.

    What is a fen in geography?
    A fen is one of the main types of wetland, the others being grassy marshes, forested swamps, and peaty bogs. Along with bogs, fens are a kind of mire. Fens are minerotrophic peatlands, usually fed by mineral-rich surface water or groundwater.

    What is the importance of fens in wetlands?
    Vegetation in all wetlands plays an important role in recycling nutrients, trapping eroding soil, and filtering out polluting chemicals such as nitrates. In addition, fens figure prominently in nearly all scenarios of CO2-induced global change because they are a major sink for atmospheric carbon.”

    What are the plants in a fen?
    Prairie fens are dominated by sedges, grasses and other grasslike vegetation, and contain very high plant diversity, including grass and wildflower species found in drier prairies. This plant community is home to many rare species, including the federally endangered Mitchell’s satyr butterfly.

    Hydrology, as seen in other wetlands, is a major determinant of fen biota and biogeochemistry. Fen soils are constantly inundated because the water table is at or near the surface. The result is anaerobic (oxygen-free) soils due to the slow rate at which oxygen diffuses into waterlogged soil. Anaerobic soils are ecologically unique because earth's atmosphere is oxygenated, while most terr…

    Unpatterned Fen Ecosystem State Rank: S5 Fens are peatlands in which groundwater or water from adjacent uplands moves through the area. As a result, plants are exposed to more nutrients, and the vegetation is typically different and more diverse than that of bogs. Peat is moderately- to well-decomposed and of variable thickness.

    Patterned Fen Ecosystem State Rank: S3 Patterned fens are floristically similar to unpatterned fens, but are typically found on gentle slopes and feature low, parallel to anastomosing, peat ridges (strings) alternating with wet hollows or shallow pools (flarks).

    Future climatic scenarios point to a threat of salinization in protected Dutch floating fen ecosystems. This is mainly caused by an increased upward seepage of saline groundwater and an increased inflow of saline surface water. The term floating fen already reveals that the root mat of this ecosystem floats on top of that surface water.
