' <br /> ' vegetation where the wetland was otherwise too deep to establish the desired plantings. <br /> The berm was not to exceed 1 foot above the normal water level of the existing wetland. <br /> , The center of the berm was left open to allow for hydrology to be shared with existing <br /> wetland on the adjacent property to the west. Hydrology was to be supplied from surface <br /> runoff and from shared hydrology from the existing wetland. <br /> ' Based on the as-built survey(Append�B)the new wetland was excavated as proposed <br /> and the wetland berm constructed as planned. The berm was approximately 1 foot above <br /> � the standing water in the rest of the basin and had an understory dominated by a <br /> hydrophytic plant community. The trees planted on the berm included tamarack, silver <br /> maple,river birch and white pine. Overall the wetland consisted of a Type 5 open water <br /> ' basin with a narrow saturated and emergent fiinge.New wetland areas were contiguous <br /> with the original wetland and consisted of pa open water area with the narrow emergent <br /> fringe. At the time of the site visit open water made up approximately 85 percent of the <br /> ' total wetland. <br /> The original wetland on the adjacent property to the west consisted of a shallow basin <br /> ' domina.ted by giant manna grass and sedge and had less than six inches of standing water <br /> at the time of the site visit. <br /> , Buffer Description <br /> A total of 11,787 square feet of buffer established adjacent to the wetland was to be seeded <br /> ' with a native mix. <br /> At the time of the site vlsit rt appeazed that areas of reed canary grass,Canada tlustle and <br /> ' common mullein had been sprayed. Reed canary grass still made up part of the plant <br /> community but cover levels were reduced from the previous year. <br /> T'he observed plant community is as follows: <br /> ■ <br /> Elymus canadensis 15 Polygonum sp. 5 <br /> ' Verbena hastata 15 Aster sp. 5 <br /> Phalaris arundinacea 10 Corryza canadensis 2 <br /> Andropogon gerardii 10 Sorgastrum nutans 2 <br /> , Poa sp. 5 Solidago sp. 2 <br /> Echinacea sp. 5 Mentha arvensis 2 <br /> Rudbeckia hirta 5 Eupatorium perfoliatum 2 <br /> ' Glyceria grandis 5 Lythrum salicaria trace <br /> Agropyron repens 5 <br /> , V. MANA E <br /> G MENT ISSUES/RECOMMENDATIONS <br /> ' PRI should continue management into 2008 to eliminate more reed canary grass and <br /> remove a11 purple loosestrife. There are no other management recommenda.tions. <br /> ' <br /> � <br />
