This evolu- <br />tion has allowed sun tolerant species to grow <br />and provide shade for the later developing more <br />sun-intolerant species. The hardwood understory <br />includes dogwood, viburnums and a variety of <br />forbs. <br /> <br />Wildlife - The proposed development involves a <br />limited variety of wildlife habitat types which <br />are variations of lowland vegetation and water's <br />edge associations. These associations provide very <br />good cover for migratory waterfowl and a limited <br />amount of nesting area for such species, especial- <br />ly mallard~, teal and pheasants. <br /> <br />I <br />II <br /> <br />Casual observations over a period of several months <br />indicate the marshes to support a number of mallards <br />(at least during fall migration) as well as muskrat. <br />Other investigators .( (1) Derrickson and (2) DNR) <br />have indicated sightings or signs of a number of <br /> <br />I <br /> <br />I <br /> <br />111-15 <br /> <br />'I <br />J <br />
