<br /> DIVISION 2.
<br /> DESIGNATION OF PROTECTED WETLANDS
<br /> Sec.78-1602.Wetland types.
<br /> The wetlands protected and regulated by this section are types 1, 2, 3, 4, 5, 6, 7, and 8 wetlands, as
<br /> defined in circular 39, 'Wetlands of the United States", 1971 edition, United States Department of the
<br /> Interior, unless the wetland is within a shoreland district in which case the more restrictive rules regarding
<br /> setbacks would apply. Protected wetlands are further defined as follows:
<br /> (1) Type 1—Seasonally flooded basins or floodplains: Type 1 wetlands are seasonally flooded basins
<br /> or flats in which soil is covered with water or is waterlogged during variable seasonal periods but
<br /> usually is well-drained during much of the growing season. Type 1 wetlands are located in
<br /> depressions and in overflow bottom lands along water courses. Vegetation varies greatly
<br /> according to the season and duration of the flooding, and includes bottom land hardwoods, as
<br /> well as herbaceous plants.
<br /> (2) Type 2--Inland fresh meadow: Occurs along the shallow edges of lakes, marshes and floodplains,
<br /> or in perched depressions. The soil is usually without standing water during much of the growing
<br /> season, but is waterlogged within at least a few inches of the surface. Vegetation includes
<br /> grasses, sedges, rushes and various herbaceous plants.
<br /> (3) Type 3—Inland shallow fresh marsh: Soil is usually water logged during the growing season, often
<br /> covered with as much as six inches or more of water. Vegetation includes grasses, bulrushes,
<br /> cattails, arrowheads, smartweeds and other emergent aquatic vegetation.
<br /> (4) Type 4--Inland deep fresh marsh: Soil covered with six inches to three feet or more of water
<br /> during growing season. Vegetation includes cattails, reeds, bulrushes and wild rice. Open water
<br /> areas may contain pondweeds, naiads, coontail, water milfoils and other submergent aquatic
<br /> vegetation.
<br /> (5) Type 5—Inland open fresh water: Water is usually less than ten feet deep and is fringed by a
<br /> border of emergent vegetation. Vegetation includes pondweeds, naiads, coontail, water milfoils
<br /> and other submergent aquatic vegetation.
<br /> (6) Type 6--Shrub swamp: Occurs along sluggish streams or on floodplains. The soil is usually
<br /> waterlogged during the growing season, and is often covered with as much as six inches of
<br /> water. Vegetation includes alder, willow and dogwood.
<br /> (7) Type 7--Wooded swamp: Occurs along sluggish streams, on floodplains, on flat perched
<br /> depressions and in shallow lake basins. The soil is waterlogged to within a few inches of its
<br /> surface during the growing season and is often covered with as much as one foot of water.
<br /> Vegetation typical to this wetland includes tamarack, white cedar, black spruce, balsam fir, red
<br /> maple and black ash.
<br /> (8) Type 8--Bog: Occurs along sluggish streams, on flat perched depressions and shallow lake
<br /> basins. The soil is waterlogged and supports a spongy covering of mosses. Vegetation typical to
<br /> this wetland type includes sphagnum moss, heath shrubs and sedges. Minnesota bogs contain
<br /> leatherleaf, Labrador tea, cranberries and pitcher plants. Scattered stunted black spruce and
<br /> tamarack also are common features of bogs.
