Upland Natural Communi#y Descriptions and Management <br />Recommenda#ions <br />The majority of upland areas in Villa Park are mostly dominated by lowland hardwood forest <br />trees that have colonized upland sites. Prior to the amval af these lowland trees, the hillsides <br />here appear to havc bcen more open, with a few scattered groves of bur and pin oak. A few <br />savanna and prairie specics linger on the south side of thc park, along an old fcnccline in an open <br />area. These are a reminder of the former openness of the park. Overall, the upland areas in Villa <br />Park have potential to improve with active management, but may zequire a concerted, long-term <br />effort. <br />Community VL-U1 <br />FIoodplain Forest <br />Qualitative Rank: D <br />Nonnative Shrub Rank: 14 <br />This comrr�unity is aC the north end of the park on either side of a ponding area.
