General Description of Survey Area

The Seepage is a shallow marshy depression running from west to east between the other areas of the Wet Woodland.  The area contains variable amounts of moisture in the soil and a small amount of shallow standing water.  Much of the area is covered by a broad-leaved tree layer.  Dappled sunlight reaches to ground level.  The Seepage Area has a lush, green appearance with many different plants growing together.
