Following taken from Intro: This report documents all aspects of invasive exotic plant management in Acadia National Park (Acadia) during the year 2009. Invasive exotic plants pose a significant risk to natural communities and visitor experiences at Acadia National Park. There are 24 invasive exotic plant species at the park that have been designated as a priority for management because they are capable of rapidly colonizing areas, altering community composition, degrading ecosystem processes, and are at population densities that make management feasibleJWeber& Rooney 2007). Eight species of exotic plants were actively managed within Acadia National Park in 2009. Populations of glossy buckthorn (Frangula alnus), shrubby St. Johnswort (Hypericum prolijicum), Amur maple (Acer ginnala), garlic mustard (Alliaria petiolata), giant hogweed (Heracleum mantegazzianum), foxglove (Digitalis purpurea), Japanese Knotweed (Fallopia japonica), and bigleaf lupine (Lupinus polyphyllus) received intensive treatment. Purple loosestrife (Lythrum salicaria), a non-native invasive plant species, was managed in the Park as it has been since 1988, excluding 2007. A full survey of wetlands and monitoring of purple loosestrife transects failed to locate loosestrife at any previously known site in the park. Early detection surveys in one recently acquired park wetland found one new population of purple loosestrife. On this parcel, loosestrife plants were aggreSSively managed with herbicide treatment. Information on the study and management of each invasive plant species follows in the sections dedicated to individual species. This report also contains an Appendix C. with a report by Lenka Sprtova, a COA student, on A Predictive Model of Glossy Buckthorn Occurance in Great Meadow Watershed. /STUDY LOCATIONS:/ /MOUNT DESERT ISLAND/Bass Harbor/Lightouse/Blackwoods Campgound/Breakneck Brook/Brown Mountain/Compass Harbor/Eagle Lake/Fernalds Point/Valley Cove/Great Meadow/Hadlock Carriage Road/Islesford Museum/Jordan Pond/Ledgelawn/Liscomb Pit/Otter Cove/Nursery/Wildwood Stables/Hull's Cove/Stanley Brook/Sieur de Monts/Jackson Lab/Thompson Island/Tarn/McFarland Hill/Seawall/Bar Island/Schooner Head/Storm Beach/Crooked Road/Duck Brook/Half Hole/Kebo Valley/Kent Field/Marshal Brook/North Breakneck/Otter Cliff/Precipice/Satterlee/Seal Cove/Sonogee/Thorndike Field/Witch Hole/Kebo Brook/Pretty Marsh/ GIS CATEGORY 2 = maps of sites provided and reference to site coordinates made in table descriptions for several species.
