brush thickets and wooded remnants. Several species of common <br />wildflowers and noxious weeds also occur abundantly including: <br />Wildflowers <br />Goldenrod <br />White Clover <br />Common Milkweed <br />Goatsbeard <br />Yarrow <br />Buttercup <br />Strawberry <br />Thimblewood <br />Solomon Seal <br />Dusty Miller Sage <br />Wild Vetch <br />Wood Sorrel <br />Birdfoot Trefoil <br />Noxious Weeds <br />Canada Thistle <br />Bull Thistle <br />Marestail <br />Nettle (Stinging) <br />Common Ragweed <br />Mullein <br />Alyssum <br />Bladder Campion <br />Leafy Spurge <br />Approximately three acres of tree clearing are anticipated due <br />to the improvements to remove obstructions and potential safety <br />hazards on the airport. Figure 2-9 illustrates the wooded areas <br />and proposed runway improvements. The acreage and general <br />composition of the wooded areas are as follows: <br />1) Plantation planting of Red Pine Row <br />2) Cottonwood, green ash, elm mix <br />3) Cemetary Plot - Bur, White Oaks and <br />Siberian Elm mix <br />0.6 acres <br />1.2 acres <br />0.9 acres <br />In addition, selective clearing of obstructions and isolated <br />clearing of smaller seedlings and brush areas is required for <br />obstruction removal and grading. Predominant vegetation types of <br />smaller trees and brush are aspen, wild plum, siberian and <br />american elm, and occassional red cedar. <br />Wildlife habitat and numbers are limited due to the suburban <br />industrial and residential development of the area. Wildlife <br />species which inhabit the site include predominantly meadowlarks, <br />red wing blackbirds, mourning doves, robins, sparrows and various <br />other songbirds. In addition, crows, grackles, starlings and <br />gulls frequent the landfill northwest of the site. Mammals <br />inhabiting the site include pocket gophers, ground squirrels and <br />cottontail rabbits. <br />A survey of wildlife was completed in 1986 for another project in <br />the immediate area. The reader is referred to Appendix A for a <br />synopsis of this survey. <br />The Minnesota Department of Natural Resources was contacted <br />regarding rare, endangered, or threatened species. No known <br />rare, endangered or threatened species of plants or wildlife <br />occur in the project area. (Appendix A) <br />2-23 <br />
