Fens
A peat accumulating wetland that receives groundwater input from surrounding or underlying mineral soil.
- Fens have a higher nutrient content than bogs, contain significant amounts of calcium, magnesium and other nutrients
- Support a high diversity of plant species
- pH circumneutral to basic due to groundwater inputs
- Often dominated by graminoid species (grasses and sedges)
- Northern white-cedar swamps are a type of fen dominated by this tree (Thuja occidentalis)
