Freshwater and Wetland Biomes

A fen is a peat-accumulating wetland fed by mineral-rich ground or surface water, which gives it a higher mineral content and a more basic pH than a bog; rich fens run near pH 7 to 5 while poor fens are more acidic, around pH 5.5 to 4. Because fens receive a continuous supply of minerals from groundwater rather than depending on precipitation alone, they support higher biodiversity and species richness than nutrient-poor bogs. Fens are dominated by sedges and mosses, particularly graminoids, with the sedge genus Carex and brown mosses typical of rich fens and Sphagnum moss more typical of poor fens, and woody vegetation is sparse or absent.

Facts
Disputed
Annual Precipitation (mm)
1143 1
1143mm is the midpoint of the cited source stated 10 to 80 inch range; fens occur from boreal to temperate zones so no single figure is fully meaningful.
Typical Low Temperature (C)
1.7 2
1.7C converts the source 35F winter figure. Same caveat as temperature-high-c.
Typical High Temperature (C)
23.9 2
23.9C converts the source 75F summer figure. Fens range from boreal groundwater-fed peatlands to temperate lowland ones, so no single figure is fully meaningful; the general freshwater range already used on Freshwater and Wetlands is applied here.
