If so, soils will be ripped to de-compact until compactionmeter readings are acceptable.·The area will be fine-graded, raked smooth and prepared forseeding or planting with specified materials.INITIAL INVASIVE MANAGEMENT·Treat and remove all approved invasive, non-native oraggressive vegetation using an appropriate herbicide(Glyphosate-based or Triclopyr-based) using a cut andwipe method.·Vegetation to be flush cut leaving the roots in place tomaintain soil stability.·Seed all exposed soils with the specified Restoration SeedMix and cover with a thin layer of clean hardwood woodchips OR hydro-seed with the ProGanics Biotic SoilMedia/Flexterra erosion control system.·Rejuvenate any native shrub species uncovered in therestoration area, if needed, with regenerative pruningtechniques to encourage new, dense growth.PHRAGMITES MANAGEMENT:·Cut and remove dead stalks prior to the start of the growingseason to facilitate the treatment process later in thegrowing season.·Where stalks occur densely enough, bundle, cut and treatcut ends using a Glyphosate-based herbicide speciallyformulated for use around aquatic environments.·If stalks are sparse, cut stalks individually and treat with anappropriate herbicide.·If stalks are too small to cut and treat, use a swipe methodto apply an appropriate herbicide to the stalks and leaves.·Manage re-growth over the following seasons using a swipemethod or low-volume foliar spray to apply herbicide to thestalks and leaves, ideally in the late summer or early fall.KNOTWEED MANAGEMENT:·In late summer or early fall, treat Japanese knotweed using a steminjection method with a Glyphosate product between the nodesinside the stem.·In winter or early spring, remove old/dead stalks from treatmentarea to ease the treatment process later in the growing season.·Repeat treatment for several growing seasons to achieve completeeradication. Knotweed which has grown back in awitch-broom-like manner should be treated with a foliar applicationmethod on an as-needed basis with a Glyphosate-based product,ideally in the late summer or early fall.MAINTENANCE & ESTABLISHMENT FOR ALL NATURALIZED AREAS(3 SEASONS MIN.):·Monitor mitigation/restoration area and performmaintenance cut and wipe treatments or hand weedinvasive, non-native, and aggressive species that havegerminated from existing seed bank, or re-sprouted fromroots after removal.·Mow/cut cool season grasses in June to encourageestablishment of warm-season grasses, if necessary.·Rejuvenate native shrub species, if needed, withregenerative pruning techniques to encourage new, densegrowth.RESTORATION PLANTING:·Mitigation plantings are to be installed once constructionand site preparation activities are complete.·Restoration plantings may be installed once invasivespecies have achieved at least 80% control.·Plantings to be installed ideally in the spring or fall.SUPPLEMENTAL IRRIGATION:·Install a temporary, above-ground irrigation system toprovide supplemental water to all plantings for 2-3 growingseasons, or until plants are fully established.APPLICATOR & OVERSIGHT QUALIFICATIONS:·Herbicide application will only be completed byMassachusetts state-licensed and insured pesticideapplicators knowledgeable with invasive, non-native, andnative plant identification, both in-leaf and bare-twig.·All restoration work will be overseen by a CertifiedEcological Restoration Practitioner (CERP).ANNUAL MONITORING REPORTS:Submit annual monitoring reports each year for three years tothe Conservation Commission. Annual monitoring reports shouldinclude:·Representative project area photographs·Project activities completed to-date·Anticipated activities to be completed during the next year·Assessment of invasive species management progress·Assessment of restoration planting establishment·Recommendations for any changes in land managementtechniques necessary to ensure the success of the project·Any unexpected or arbitrary changes to the project areaMITIGATION AREA (2,000 SF +/-)EXISTING SITE FEATURE TO BEREMOVED OR RECONFIGUREDINVASIVE NORWAY MAPLE TREEFOR REMOVALPLANT SCHEDULE- PHASE 1 INVASIVE REMOVAL AREASYMBOL SCIENTIFIC NAMECOMMON NAMEQTY.SIZETREESArAcer rubrumRed maple1#15 or equiv.WOODY SHRUBSCalClethra alnifoliaClethra20 #2 - #5CoCephalanthus occidentalisButtonbush20 #2 - #5IvIlex verticillataWinterberry20 #2 - #5LbLindera benzoinSpicebush10 #2 - #5VcVaccinium corymbosumHighbush blueberry18 #2 - #5VdViburnum dentatumArrowwood viburnum18 #2 - #5VtViburnum trilobumAmerican cranberrybush10 #2 - #5NOT FORCONSTRUCTION(ISSUED FORPERMITTING)KNOTWEED MANAGEMENT- PHASE 1*A PLANTING PLAN FOR PHASES 2 & 3WILL BE PROVIDED FOR APPROVAL BYTHE CONSERVATION ADMINISTRATORPRIOR TO IMPLEMENTATION.*SEE SITE PLAN BY DOWN CAPE ENGINEERING FORA BREAKDOWN OF MITIGATION CALCULATIONS.
