• Bogs are a unique type of wetland that are characterized by spongy peat deposits, acidic waters and a floor covered by a thick carpet of sphagnum moss. Bogs receive much of their water from precipitation rather than from runoff, groundwater or streams. As a result, bogs are low in the nutrients needed for plant growth, a condition that is enhanced by acid forming peat mosses.
  • Bogs can develop in two ways. First bogs can form slowly while sphagnum moss grows over the lake or they can form as sphagnum moss covers dry land and prevent the water from leaving the surface. Then acidic peat deposits build up. The plants that inhabit bogs have special adoptions to low nutrient levels and acidic waters such as carnivorous plants
  • Bogs serve an important ecological function in preventing downstream flooding by absorbing precipitation. Bogs support some of the most interesting plants in the United States (like the carnivorous Sundew), and provide habitat to animals threatened by human encroachment.
  • Bogs have been in decline because the land has been drained for cropland, and mined for their peat which was used as a fuel and a soil conditioner.
  • Recently, bogs have been recognized for their role in regulating the global climate by storing large amounts of carbon in peat deposits. Bogs are unique communities that can be destroyed in a matter of days, but require hundreds, if not thousands, of years to form naturally. From EPA
