The wetland is <br /> classified as Manage 2 a d requires a 25 foot upland buffer and 20 foot <br /> setback from the buffer. <br /> Buffer Condition and R quirements <br /> A site evaluation was co pleted on 13 November 2007 to determine the <br /> condition of the vegetati n in the existing upland buffer. Currently a large <br /> portion (south side) of the buffer is turf grass and the remainder of the buffer <br /> has been left in a natural�condition and it sparsely wooded with shrubs, � <br /> grasses and forbs. This portion of the buffer currently contains buckthorn and <br /> prickly ash. According to Division 3 sec. 78-1605 turf grass, buckthorn and <br /> prickly ash are considered to be an undesirable plant species and should be <br /> removed from the buffer area. After the turF is removed it is required to be <br /> planted or seeded with native species and it is recommended that <br /> supplemental or spot seeding or planting of herbaceous vegetation occur in <br /> the natural area due to the lack of diversity of herbaceous cover and <br /> disturbance that may occur due to buckthorn removal. <br /> The applicant will need to provide a Management/Landscaping plan that <br /> includes the following: <br /> 1. Method proposed to be used to control buckthorn (MN DNR website <br /> source for options). All buckthorn removal should be done using hand <br /> tools as large equipment can further disrupt the wetland buffer. At a � <br /> minimum buckthorn should be cut and the remaining stems should be <br /> treated with an approved herbicide following label instructions. <br /> Treating the cut stumps will help prevent regrowth of the buckthorn. <br /> 2. Method of establishing native vegetation in turf areas (MN BWSR Web <br /> Site— Publication: "Restoring & Managing Native Wetland and Upland <br /> Vegetation" source for options). <br /> 3. Species proposed to be seeded or planted. According to the ordinance <br /> Div. 3 Sec. 78-1605 (3) the seed mix must contain at least 12 pounds � <br /> (PLS) per acre of native prairie grass seed and 5 pounds (PLS) per <br />
