Presettlement Vegetation (Circa 1850) <br />According to vegetation data compiled from the Original Land Survey Notes of Minnesota (circa <br />1850), and mapped by F.J. Marschner (1975), the natural vegetation of the Foxborough <br />Conservation Development and surrounding landscape at the time of European settlement was <br />comprised predominantly of oak openings and barrens (oak savanna/woodland) in the uplands, <br />and wet prairie within lower lying wetland areas extending north and south along the margins of <br />the chain of lakes. The pre- settlement vegetation of Anoka County was managed by occasional <br />to frequent wildfires during periods of drought. Occasional areas of mesic hardwood forest <br />( "Bog Woods ") were also in the vicinity of the Foxborough site, typically occurring in those <br />portions of the landscape that wildfires could not penetrate (such as isolated islands and large <br />isolated topographic depressions; Figure 3). <br />Figure 3.
