PURPOSE <br /> The invasive species located on this site include common buckthorn(Rhamnus cathartica) <br /> and reed canary grass (Phalaris arundinacea). These species are considered invasive <br /> terrestrial plants by the Minnesota Department of Natural Resources and should to be <br /> managed accordingly. <br /> The vegetation management plan is to focus on controlling invasive species within the <br /> buffer areas only. Therefore, the following vegetation management plan describes <br /> effective methods to remove the different invasive plant species along with the re- <br /> establishment of native vegetation within the wetland buffer areas. In addition, ISG <br /> recommends that certain highly aggressive invasive plant species located within the <br /> wetlands and upland also be controlled while they are still in a manageable state. <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 Vegetation <br /> Management Plan has been created as one of the conservation strategies used within the <br /> Conservation Design Master Plan to improve the sites' ecological assets. The developer is <br /> responsible for initiating the vegetation management plan immediately after development <br /> plans have been established. Vegetation management will initially begin within the area of <br /> construction and then be applied concurrently with the construction to the remainder of the <br /> area. The vegetation management will continue annually until the invasive vegetation is <br /> eradicated. See the Schedule of Activities sections below for a description of the timeline <br /> involved with the vegetation 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 include <br /> the control of existing non-native and invasive vegetation, the encouragement of native <br /> species,and future monitoring of the site to discover any newly established invasive plants. <br /> Native species that are dominant fall into the Northern Wet Meadow/Carr classification <br /> according to the Minnesota DNR Ecological Classification System (Dunevitz and Lane, <br /> 2004). Common buckthorn and reed canary grass occurs at both wetland site and upland <br /> areas, and are considered to be invasive within this community type. We have provided <br /> control recommendations for both the buckthorn and reed cry grass observed in the <br /> wetland and buffer areas along with the other invasive species found on site. <br /> The removal and annual control of invasives in the buffer areas will be either self <br /> performed by the developer or contracted out at the developer's expense. This will also be <br /> the case for the installation of the native vegetation. After the initial remediation of the <br /> buffer area is complete, ISG, or another contractor chosen by the developer, will monitor <br /> the buffer area and submit annual reports to the city of Orono describing the progression <br /> of the management area if desired by regulatory personnel. <br /> Frenzel Additior -800 North Arm Dr. <br /> Vegetation Management Plan <br />
