1 <br /> wetland areas 1, 3, 4 and b. Wetland 5, in the delieantion report, is not part of the <br /> Conservation Design anc� the platting process. We have provided control <br /> recommendations for the buckthorn, garlic mustard and reed canary grass observed in the <br /> wetland and bui�er areas. A list of desirable native species that are known to accur within <br /> the Northern Wet Meadovv/Carr community according to Dunevitz and Lane (2Q04} and <br /> in Restoring and Mana.ging Native Wetland and Upland Vegetation (R. 7acobson, 2006} <br /> is also provided (Attachment B). <br /> The removal and annual control of invasives in the buffer areas will be either self <br /> perfortned by the developer or contracted out at the developer's expense. 'I'his will also <br /> be the case for the installation of the native vegetation. After the initial remediation of the <br /> buffer area is complete, Svoboda. Ecological Resources (SER} (or another contractor <br /> chosen by the developer) will monitor the buffer azea and submit annual reports to the <br /> city of Orono describing the progession of the management area if desired by regulatory <br /> personnel. <br /> The developer will retain ,�R as a consultant (or other cantractor of tl�eir choice) for the <br /> purpose of monitoring the vegetation management activities within the buffer azea for the <br /> time period of three years, where the chosen contractar will visit the site twice per year. <br /> The developer will request notification by the city of Orono before an on-site inspaction <br /> is conducted by the ciry (or its designated authority}. The developer's inspection <br /> contractor will report the progress of the monitoring activities to the developer after each <br /> site visit and will also discuss any issues with the city of �rono at the time of the <br /> scheduled on-site inspectian. <br /> CONTROL OF EXISTING BUCKTHORN <br /> Common buckthorn (Rhamnus cathartica) is established along the shoreline of Tanager <br /> Lake and may be present in isolated pockets elsewhere on the parcel. Seed carried by <br /> birds has helped introduce this species throughout the regian. Bucl�cthorn generally does <br /> well in moderately shady forested areas. Buckthorn can usually be found throughout the <br /> Twin Gi�ies in fragmented woods or city lots and invades first from forest edges and <br /> slowly moves inwazc�s. Buckthom has been successful at establishing itself in these <br /> woods due to its long growing season, rapid growth rate, and copious frait production. <br /> This establishment of buckthorn has multiple ecolagical detriments such as out <br /> competing native plants, disrupti.ng the forest structure, and reducing plant species <br /> diversity. These detriments ha.ve Iead to major efforts to grevent the spread of buckthorn <br /> and restore the forests to an ecologically productive and functional state. Proper <br /> management and yearly follow-ups wili be necessary for this site due to the seed bank <br /> left behind by buckthorn which can regenerate for up to 6 yea�rs after removal has taken <br /> place. <br /> To eradicate the existing buckthorn, cut the plants and treat the stumps with herbicide <br /> such as Roundup (or its counterpart in wet areas, Rodeo}. Application should be full- <br /> strength. VJhen cutting the larger buckthorn,place flags near the stump so that stumps are <br /> not missed when the chemical treatment is applied. Herbicide treatment needs to occur <br /> within two hours of cutting to be effective. <br /> Svoboda Ecological Resources 7 185-225 Old Crystal Bay Road <br /> Project No.:2015-013 Homestead Partners <br />
