Vegetation Management Plan <br /> PURPOSE <br /> The invasive species located on this site include common buckthorn (Rhamnus <br /> cathartica), reed canary grass (Phalaris arundinacea), and garlic mustard (Alliaria <br /> petiolata). These species are considered invasive terrestrial plants by the Minnesota <br /> Department of Natural Resources and should to be managed accordingly. <br /> The vegetation management plan addresses the control of invasive species in all four of <br /> the proposed lots. In large part, the invasive species such as buckthorn occur primarily <br /> along the edges of the wetland areas and within areas that will be part of the wetland <br /> buffer. The reed canary grass present in the wetland along the regional trail is for the <br /> most part,outside of the platted lots and therefore beyond the control of the applicant. <br /> Reed canary grass is present in Wetlands 1,4, 5 and 6. With regard to Wetland 4,the reed <br /> canary grass will be eliminated as part of the construction of the Heritage Lane extension. <br /> Revegetation of the area will not include reed canary grass in the seed mix. <br /> SER recommends that these highly aggressive invasive plant species located within the <br /> wetlands and upland be controlled as circumstances present themselves such as part of an <br /> overall site landscaping plan. Removal of the buckthorn masses may result in large areas <br /> of denudation so buckthorn removal is not recommended on a large scale unless it is part <br /> of an overall project wide revegetation effort. <br /> Pursuant to Orono Municipal Code, Chapter 78, Article XII, Section 78-1632, "The <br /> Conservation Design Master Planning requirements of this article apply to all proposed <br /> residential subdivisions or multi-unit residential developments greater than five acres in <br /> total area or guided for urban density (greater than one unit per two acres)". The <br /> Vegetation Management Plan has been created as one of the conservation strategies used <br /> within the Conservation Design Master Plan to improve the sites' ecological assets. The <br /> developer is responsible for initiating the vegetation management plan immediately after <br /> development plans have been established. Selective vegetation management will initially <br /> begin within the area of construction and then be applied concurrently with the <br /> construction to the remainder of the area as appropriate. The vegetation management will <br /> continue annually until the invasive vegetation is eradicated. See the Schedule of <br /> Activities sections below for a description of the timeline involved with the vegetation <br /> management activities. <br /> METHODS <br /> The wetland buffer areas will require aggressive management to be preserved in a natural <br /> condition with predominantly native, non-invasive plant species. Management will <br /> include the control of existing non-native and invasive vegetation, the encouragement of <br /> native species, and future monitoring of the site to discover any newly established <br /> invasive plants.Native species that are dominant fall into the Northern Wet Meadow/Carr <br /> classification according to the Minnesota DNR Ecological Classification System <br /> Svoboda Ecological Resources 6 1700 Shoreline Drive <br /> Project No.:2015-004 Irwin Jacobs <br />
