Wetland Natura� �ommunity Descr�ptions and <br />Management Recommendations <br />From examination of historic aerial photographs, wetlands have remained relatively unchanged <br />in size and location from before development. Some of the wetland types have changcci due to <br />in#luences of stormwater inp�ts or lower water levels due to draining or artificial outIets. Other <br />wetlands have last hydrologic inputs due to diversion of surface water ffows from the <br />deveiopment of curbed roads and catch basins. Invasive vegetation has also affected these <br />wetlands. Turf areas cor�tributing nutrients to the wetiand and disc golf activities compactina soil <br />and disturbing the vegetation have reduced the ecological integrity of many of the wetland basins <br />within this park. Glossy and comrr�on 6uckthorn, purple loosestrife, and reed canary grass where <br />all com�non in the park's wetlands. <br />Locations of the improvements discussed in the following paragraphs are shown in figure b.2 <br />Community AC-Wl <br />Shrub-carr <br />Qualitative Rank: Low <br />Area: 1.1 {2.1 total) <br />This is a shrub-carr wetland communiEy that is dominated by puzple loosestrife and sandbar <br />willow. Other ve�etation within the basin includes water plantain, ditch stonecrop, silver maple, <br />horsetail, bog birch, and wool grass. <br />This wetland currently has a ditch that drains Wetland W2 into this basin from the southeast. It <br />currently is a shrub-carr and has not been hydrologicaliy altered. The main alteration to tnis <br />basin is a purple loosestrife infestation that wotild be categoi-ized as a hi�h-density infestation <br />and requires biolobical control utilizing beetles. <br />, . � <br />Community Activi#y :, �rioiity • Estimated Cost �� Coznments <br />_ <br />_ : . . .. <br />AC-W I Control purple High N/A Ivlonitoring bectle population <br />loosestrife <br />i itv nf Roseville 71 <br />Parks Narrrral Resotrrce rtilctiic:gerlre�rt <br />
