The upland mixes are designed to be "planted into existing temporary mixes". As such, they do not contain a high percentage of cover crops. Because of this, a cover crop of winter wheat and annual rye amass will be employed. Tree Preservation As discussed previously, a significant portion of the woodland located westerly on the property is of high quality. It is the intent of the developer to preserve that portion which is of highest quality. As shown on the plans for the site, the area of tree preservation will be approximately 3.52 acres. Throughout the stand, though not in large contiguous groups, there are other significant trees. These trees are desirable species (i.e. Querezas, Prunus, and Carya) of significant size, with good growth form and no evident pathogenic infections. Wherever lot placement and road alignment allow, these trees will be preserved. Further to the south, all trees within the Type 7 wetland will remain. It is quite likely that the proposed hydrologic improvements to this large wetland complex will result in increased tamarack propagation. Mortality of three large Ouercus ellipsoidalis was observed during the tree survey performed on June 1, 2004. These trees were located in the southwest quarter of the northeast quarter of the stand. One of the trees had leaved out earlier in the year. The observed conditions were symptomatic of a systemic pathogen such as Oak Wilt. During any tree removal in the area, all oaks exhibiting symptoms indicative of Oak Wilt will be disposed of properly to avoid infection of remaining oaks. The removed oaks will either be burned or be disposed of in a manner approved by city officials and the county forester. In addition, a vibratory plow will be used to sever any roots that may have grafted with adjacent remaining oaks. The high quality stand of trees will be immediately adjacent to the wetland labeled southwest and to the proposed prairie restoration to the east_ This will offer a diversity of habitat and a natural, unfragmented corridor for wildlife. This comdor will continue off the property to the south one-half mile, following Trott Brook, and one-half mile to the west through the large Type 7 wetland and associated woodland. Other trees that will remain during construction are along the western boundary between Sunset Ridge and the proposed development. These trees will not only provide a natural buffer between Sunset Ridge and River Park, they will also serve to extend the natural corridor to the north. Prairie Restoration Within the current NSP easement, we will work with NSP in an attempt to create native prairie. Combined with the wetland restoration and woodland preservation, this would
