  "definition": "1. A type of wetland that accumulates peat deposits. Fens are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium.\n\n2. A type of wet meadow with highly alkaline soil. Vegetation is primarily composed of herbaceous species, encircled by zones of plants of increasing height and woodiness.\n\n3. Peat-forming wetlands that receive nutrients from sources other than precipitation: usually from upslope sources through drainage from surrounding mineral soils and from groundwater movement. Fens differ from bogs because they are less acidic and have higher nutrient levels.",
