Describe measures to minimize or avoid adverse impacts. Existing Conditions The existing fish, wildlife, and ecologically sensitive resources have been analyzed based on previous studies, historical aerial photos, and site visits during 2011. The habitat available for wildlife is a function of the vegetation and land cover present discussed in Item 10. The habitat on the site is described below. • Mississippi River: Mississippi River is adjacent to the study area to the west. While not directly within the study area, the Mississippi River provides a significant habitat corridor for fish and wildlife. The River is designated as "Scenic" in this area. A portion of the study area is within the City's designated Wild and Scenic overlay district. Wetlands: Approximately 8 acres of the site contains wetlands. The wetlands on the site have been degraded by adjacent agricultural activity, but they do offer habitat for species accustomed to disturbance. Red-winged black birds were the most abundant species observed during the site visit. Great blue herons were also seen flying over the area. Chorus frogs were noted in the wetlands. The wetland that crosses the site in the northern portion of the study area is part of a larger wetland complex that extends beyond the study area boundaries. Again, this is not a pristine wetland and it contains both native and invasive species; however, its contiguous nature that provides a natural corridor to the east and west does provide some habitat within the study area. Figure 11-1 shows the National Wetlands Inventory and DNR Public Water wetlands within and adjacent to the study area. Forest and Woodland Communities: Approximately 33 acres of the site contains forested and woodland areas. The Elk River Natural Resources Inventory report (2004) was reviewed for a description of these areas. Floodplain forest is present to the west, adjacent to the Mississippi River. Portions of this forested area are low quality. An oak woodland/brushland community is also present in the southwestern portion of the study area. This woodland is currently in poor condition, likely due to a lack of grazing or fire regime, but has moderate restoration potential. Other small sections of forest exist as wind breaks and small groves along the border of the agricultural fields. Agricultural Area: Approximately 196 acres of the site are in agricultural production. This activity is generally located throughout most of the study area with the exception of the wetlands and slopes near the Mississippi River. Most or a part of these areas have been in agricultural production since at least 1937. The agricultural areas are expected to provide limited habitat value, except for resting areas during bird migration. During the site visit, species typical of agricultural areas were noted, including red-tailed hawk, Eastern Kingbird, City of Elk River Draft Alternative Urban Areawide Review July 2011 Page 28 of 84
