    1. National Park Service, Alaska Region Exotic Plant Management Team

    2. Program Objectives Regional strike team Prevention Detection Control Monitoring Restoration Inventory needed to prioritize particular species and sites

    3. Exotic Plants in Alaska >100 species in early stages of invasion 54 million acres of NPS lands, mostly restricted to disturbance Early detection and rapid response Mapping essential for planning, execution, recording, and evaluation

    4. GPS Survey Protocol Trimble GeoXT units with custom data dictionary Observer chooses point, line, or polygon Spatial Fields: Associated Park Location description Buffer width Ecological Fields: Species, phenology Percent cover, stem count Disturbance type Action taken Control effort

    5. From GPS to GIS Pathfinder Office differential correction spatial editing export GIS shapefile ArcGIS Buffer using the Geoprocessing Toolbox Merge polygon shapefiles into 1 for all annual activity

    6. Data Utility Map generation for planning/prioritization Monitoring infestations and determining rate of spread Evaluating control success Relocating infestations Calculating acreages for reporting Precision is essential

    8. Statewide Database akweeds.uaa.alaska.edu Developed in partnership with Forest Service, Natural Heritage Program, and Alaska Science Center Track species distributions across boundaries Web-enabled data entry for exotic plant locations Share information on species’ biology and control/restoration strategies

    9. Summary Exotic plants are a rapidly growing threat to Alaskan ecosystems Appropriate management requires regular field surveys and mapping Modern GPS & GIS tools enable greater range of data utility The more eyes (and GPS units) the better for finding and reporting these plants!
