<br />Natural Resource Inventory Results <br /> <br />1,413 individual natural communities were documented, covering a total of 15,326 <br />acres. These remnants represent a variety of distinct natural community types <br />including forest, woodland, shrublan<;f, herbaceous wetlands, and grasslands, as well <br />as areas of open water (lakes and ponds). The following pages include a summary of <br />the major natural community types encountered in the City, with general descriptions. <br />It is important to note that there are numerous other natural community types that <br />occur less frequently in the city. Descriptions for these community types can be found <br />in the MLCCS User Manual. The complete 273 page MLCCS Manual can be <br />viewed/downloaded on the MN DNR web site at the following address: <br />htto://www.dnr.state.mn.lIs/mlccs/index.htm!. <br /> <br />NOTE: A figure summarizing the location of natural areas identified can be <br />found on the plotted map that accompanies this report.

The most <br />common of these was oak forest of unspecified <br />subtype (109 occurrences totaling 1,175 acres). <br />Other oak forests include Red maple subtype (1 <br />occurrence of 14 acres), mesic oak forest (16 <br />occurrences totaling 363 acres), and dry oak <br />forest (109 occurrence of 2,156 acres). <br /> <br />Northern red oaks (Quercus rubra), white oaks <br />(Quercus alba), or bur oaks (Quercus <br />macrocarpa) dominate mesic stands of oak forest. <br />These stands occur on sites that had fewer severe <br />fires before European settlement than the sites on <br />which dry mixed oak forest occurs. Mesic stands <br />most likely were always forest, rather than <br />woodland or savanna.
