Tartarian honeysuckle. In Roseville, the presence of these exotic species have sigr�ifieantEy <br />reducec! species diversity of most Oak Woodland — Brushland Communities. <br />Lowland Hardwoocf Forest - A deciduous forest with a varial�le canopy, with coverage from <br />about 50 to 100 percent. Lowland hardwood forests occur on mineral soils and are often Iocated <br />near the margins of lakes and wetlands, in ravines, and on �he lower portions of north-facing <br />slopes. <br />Common tree species include, green ash, American elm, eastern cottonwood, basswood, hur oak <br />and hackberry. Subcanopy trees may include ironwood, red elm and boxelder. Cominon shrubs <br />include pagoda dogwood, prickly ash, hazelnnt, and gray dogwood. The ground layer may <br />include Virginia creeper, goIdenglow, Virginia and Canada wildrye, sedges, wood�and horsetail, <br />rough hedae nettle and jack-in-the-pulpit. A wide range of comtnon forest animals and birds use <br />thcse forests as habitats. These forests are often degraded by overgrazing and/or logged using <br />unsustainable methods. <br />Many Lowland Hardwood Forests have been invaded by exotic species such as buckthorn and <br />reed canary �rass. Also, in recent times the trees and other sgecies typical of iowland hardwood <br />forest have been successful in colonizing upland forests and open areas that they would not have <br />historically occurred in. This is largely a result of the lack of periodic fire, grazin�, haying, or <br />mowing in these areas. <br />WETLAZVn CO�U�TIES <br />(As described in Wetland Planls and Plant Commrinities of Minnesota & Wisconsin, Second Ed'etion — Steve D. <br />Eggers & Donald M. Reed) <br />Deep Marshes — Deep marsh plan communities have standing water depths of between 6-inches <br />and 3 or more feet during the growing season. Herbaceous emergcnt, floating, floating-leaved, <br />and submer�ent vegetation cornpose this community, with major dominance by cattaits, hard- <br />stem bulrush, pickerel weed, giant bur-recd, phragmites, wild rice, pond weeds, and/or water <br />lilies. <br />Shallow Marshes — Shallow marsh plant communities have soils that are saturated to inundated <br />by standing water up to 6-inches in depth throughout most of the brawing seasan.
