R.23W. <br /> Report prepared by: Date: <br /> Applied Ecological Services, Inc. December 16, 2015 <br /> PROJECT OVERVIEW <br /> The Nelson Restoration project entails ecological restoration/enhancement of a 2.98-acre <br /> severely degraded shallow cattail marsh, plus enhancement of an additional 2.68 acres of <br /> upland buffer located in Orono Township, Minnesota (Figure 1). Pre-construction wetland <br /> vegetation was dominated by invasive cattails, purple loosestrife, and reed canary grass. Using <br /> the Minnesota Routine Assessment Method (MnRAM), the wetland scored as "Low" to <br /> "Moderate" in almost every category, with Vegetative Diversity/Integrity scoring "Low"for all <br /> wetland plant communities present. <br /> In early 2015, in compliance with acquired permits, approximately 2,588 cubic yards of wetland <br /> soils (:54 ft deep) were excavated from a 0.5-acre portion of the wetland in order to create an <br /> area of Deep Marsh habitat and to control invasive vegetation (Figure 2). The upper foot of soil <br /> (approximately 807 cubic yards) was infested with propagules of invasive vegetation (including <br /> cattail tubers and purple loosestrife seeds), and therefore was removed from the site. The <br /> remainder of the excavated material was thin-spread (:51 ft thick) over lower portions of the <br /> wetland to a maximum elevation of 964.5 feet, lower than the elevation of the delineated <br /> wetland boundary, in order to maintain wetland conditions and create saturated Wet Meadow <br /> habitat (Figure 2). In order to maintain possible flows in the wetland, two meandering swales <br /> were constructed between the Deep Marsh area and two existing culverts beneath Tonkawa <br /> Road. The project is expected to restore the wetland to a diverse habitat complex of native <br /> MN Board of Water and Soil Resources <br /> Nelson Restoration Site(12-0975)—2015 Monitoring Report 1 <br />
