Community AC -W3 <br />Shallow Marsh <br />Qualitative Rank: Medium/Low <br />Area: 0.3 acres <br />The predominate vegetation in this basin includes cattail and duckweed. Other vegetation found <br />in the basin is smartweed, sandbar willow and reed canary grass. This wetland was categorized <br />as a medium /low ranking due to it containing 60% invasive vegetation. <br />Wetland buffer with signage around this basin would provide treatment of adjacent turf grass and <br />limit human disturbance. This wetland basin is small and currently does not have hydrologic <br />alteration. Natural fall draw down in this basin would allow for maintenance of the cattail by <br />cutting. Natural flooding of this basin in the spring should remove or set back the cattail. This <br />along with shallow marsh plantings would improve the ecological integrity of this basin. <br />Community <br />Activity <br />Priority <br />Estimated Cost <br />Comments <br />AC -W3 <br />Cut cattail <br />Low <br />$150.00 <br />Allow for planting of more <br />diverse species <br />AC -W3 <br />Planting shallow <br />Low <br />$700.00 <br />Establish more diverse species. <br />marsh species <br />AC -W3 <br />Buffer Strip <br />Low <br />3 -signs at $60.00 <br />Marks the upslope edge of <br />Signage <br />buffer to limit human <br />disturbance in basin and <br />provide education. <br />AC -W3 <br />Establish <br />Low <br />$250.00 <br />Provide treatment from turf and <br />Buffer <br />limit human disturbance. <br />Community AC -W4 <br />Shallow Open Water <br />Qualitative Rank: Low <br />Area: 0.07 acres <br />This is a small depression that receives runoff from the parking lot. This wetland currently does <br />not contain any aquatic vegetation besides duckweed. This basin is impacted by the adjacent <br />land -use of the disc golf course and a dense canopy that limits light penetration. Restoration of <br />the vegetation community would involve canopy thinning and plant introduction for a partial <br />sae environment. <br />City of Roseville 74 <br />Parks Natural Resource Management <br />
