. I,_..� <br /> e.-- <br /> ► Natural Community Quality Modifier(M 34x) <br /> i The M_34x modifier was developed as part of MLCCS methodology as a cursory <br /> i method to assess the general natural quality of natural community and semi-natural <br /> ► land cover types. The natural plant community sites can be given a natural quality <br /> I ranking, based on the DNR's Natural Heritage's Element Occurrence Ranking <br /> I Guidelines~ (EOR). This modifier has four general categories: High Quality Natural <br /> � Community (A), Good Quality Natural Community (B), Moderate Comdition Natural <br /> � Community (C), and Poor Condtion Natural Community (D). However, the <br /> � assessment method is b.ased on general ecological variables, and is applied in the <br /> � same manner for all natural community types. The following is the description of the <br /> � M_34x modifier from the MLCCS training manual: <br /> 1 <br /> � A = highest quality natural community, no disturbances and natural processes intact. Site <br /> � must be visited entirely or partially to accurately assess its natural quality at this level <br /> . <br /> (fld_level = 3 or 4). <br /> B = good quality natural community. Has its natural processes intact, but shows signs of <br /> past human impacts. Low levels�of exotics. Site must be visited entirely or partially to <br /> accurately assess its natural quality at this level (fld_level = 3 or 4). <br /> C = moderate condition natural community with obvious past disturbance but is still clearly <br /> recognizable as a native community. Not dominated by weedy species in any layer. <br /> Minimally, the site must be visited from the edge to accurately assess its natural quality at <br /> this level (fld_level = 2, 3 or 4). <br /> D = poor condition of a natural community. Includes some natives, but is dominated by non- <br /> � natives and/or is widely disturbed and altered. Herbaceous communities may be assessed <br /> with this ranking from a distance (fld_level = 1) if large masses of invasive species are <br /> present and the entire community is visible. <br />
