Morrison County that are included in the Mississippi Headwaters Board comprehensive plan dated <br /> February 12, 1981; and other waters of the state with high water quality, wilderness characteristics, _ <br /> unique scientific or ecological significance,exceptional recreational value, or other special qualities <br /> which warrant siringent protection from pollution. <br /> One Scientific and Natural Area (SNA) is designated in, Subp. 4, Wolsfeld Woods. One�additional <br /> SNA, Wood-RiIl SNA, which is listed in A Guide to Minnesota's Scientific and Natural Areas <br /> (MnDNR, 1999), is also present within the District. Based on a review of ORVWs in MN Rules <br /> 7050.0180, there are no wild, scenic, or recreational river segments, no calcareous fens, and no Iake <br /> trout lakes. There are no wetlands designated or associated with ORVWs in the District. <br /> The watersheds included in the Functional Assessment of Wetlands within the Minnehaha Creek <br /> Watershed District (FAW within the MCWD) do not lie within the areas described within this <br /> definition of"outstanding resource value waters". <br /> 4.3.2 Calcareous Fens <br /> Calcareous fen are defined in MN Rules 8420.1020 as peat-accumulating wetlands dominated by <br /> distinct groundwater inflows having specific chemical characteristics. T'he water is characterized as <br /> circumneutral to alkaline, with high concentrations of calcium and low dissolved oxygen content. <br /> The chemistry provides an environment for specific and often rare hydrophytic plants (MN Rules <br /> 8420.1020). Minnesota Rules 8420 to 1010-1070 sets out minimum standards and criteria for the <br /> identification, protection, and management of calcareous fens as authorized by Minnesota Statutes, <br /> section 103G.223. The MnDNR is charged with identifying and maintaining a Iist of calcareous fens <br /> in the state. The MnDNR's database of calcareous fens (MnDNR,-1995) does not list any fens in <br /> Hennepin County and only one in Carver County; Seminary Fen in southern Chanhassen. The listings <br /> in the Classifications for Waters in Major Surface (MN Rtiles 7050.0470) does not list any calcareous <br /> fens within the District nor does the rules for Nondegradation of Outstanding Resource Value Waters <br /> (MN Rules 7050.0180, Subp. 6). Finally, no calcareous fens were identified during the field <br /> assessments within the District. <br /> 4.3.3 Scienfific and Natural Areas <br /> State scientific and natural areas (SNA) are established to protect and perpetuate, in an undisturbed <br /> natural state, those natural features which possess exceptional scientific or educational value (MN <br /> Statutes 86A.05).. This may include but are not limited to any of the following features: geological <br /> \\fred\wp�23'�?7�D06�Reports�Final Report\Wetland mgmt�lan dft011503.doc 4-18 <br />
