Alaska Wetland Information

The State of Alaska includes approximately 63% of the nation’s wetland ecosystems (Hall et al. 1994). Estimates place the total acreage at approximately 130 million acres or about one-third of the State. Wetlands help maintain water quality by slowly filtering excess nutrients, sediments, and pollutants before water seeps into rivers, streams, and underground aquifers. They also offer a breeding ground and/or habitat for fish, wildlife, and plants. Wetlands are areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include tundra, permafrost areas, marshes, bogs, and similar areas.
