Management Plans For Invasive Plant Species of Acadia National Park

Weber, Jill; Rooney, Sally

From the executive summary: 'The main objective of the current work was to develop management plans for the most problematic invasive species at Acadia National Park (ACAD). Plans describe each species’ abundance at ACAD; background information regarding habitat and species biology; goals of management; methods used for control, as reported in the literature or in use by other agencies; experimental treatments and recommended monitoring protocols for managed populations. Plans were written for 22 species: Amur maple (Acer ginnala) Norway maple (Acer platanoides) Garlic mustard (Alliaria petiolata) Barberries (Berberis X ottawensis, B. thunbergii, B. vulgaris) European bittercress (Cardamine impatiens) Oriental bittersweet (Celastrus orbiculata) Canada thistle (Cirsium arvense) Burning bush (Euonymus alatus) Japanese knotweed (Fallopia japonica) Alder-leaved buckthorn (Frangula alnus) Shrubby St. Johnswort (Hypericum prolificum) Non-native honeysuckle species (Lonicera spp. and L. japonica) Privet (Ligustrum spp.) Forest woodrush (Luzula luzuloides) Ninebark (Physocarpus opulifolius) Black locust (Robinia pseudoacacia) Multiflora rose (Rosa multiflora) Bittersweet nightshade (Solanum dulcamara) Coltsfoot (Tussilago farfara). Eradication, prevention of spread, public education, reduction in area and/or number of individuals and prevention of seed production are goals identified in the plans. Recommended control methods are: pulling/digging; removal of flowers/fruits; mowing/cutting; applying glyphosate (cut stem or foliar); and applying triclopyr (cut stem or foliar). The report also discusses data management and invasives management from a whole park, rather than species by species perspective. Recommendations for priority actions are included.' /STUDY LOCATIONS:/ /MOUNT DESERT ISLAND/SCHOODIC PENINSULA/
