  1. Advances in an Alabama Strategy To Target Priority Invasives Using New Web Databases James H. Miller Southern Research Station US Forest Service Auburn University, Alabama Major Contributions by Erwin Chambliss and Vic Rudis, SRS

  2. The Main Portal to Invasive Knowledge Southeast Exotic Pest Plantand ALIPC Websites se-eppc.org

  3. View and Input Infestations

  4. Nature Serve’s I-Rank of Invasive Plants

  5. www.invasive.org FIA Survey Guide – 33 Taxa or about 40 Species …..And 20 additional species in Florida

  6. Invasive Plant Taxa Surveyed Regional Florida Trees 6 6 Shrubs 8 5 Vines 8 3 Grasses 6 1 Ferns 1 2 Forbs 4 1 Subshrubs - 2 Total 33 20

  7. SRS FIA Survey of Invasive Plants Initiated in 2001 and “phased in” until 2003 States vary in initiation of new cycle 1-7+ years to complete complete State while MS is underway and OK not started.

  8. Percent Completion of Plots on Posted on SRS FIA Website 66% 60% 80% 60% 0 % 80% 80% O% * 100 % 57% 120% 100% 60% * Expected June 15 2007

  9. FIA Forest Survey Plots . 2 24 ft radius (1/24 acre) 120 ft between centers . 1 . . 4 3 Microplot measurement of seedlings and saplings A Sample Plot is randomly positioned within each hexagon Sample Plots contain 4 Subplots each 1/24 acre 1 subplot = 1,500 acres

  10. Survey of Forest Exotic Pest Plants Data Collected in Forested Subplots VAST OPPORTUNITIES FOR CORRELATIVE AND MODELLING RESEARCH • Landscape Context • Geographic Coordinates • Elevation • Proximity to Ag, Roads, Urban, Water • Size of forest fragment • Non-forest edge conditions • Subplot/Condition • Slope, Aspect, Physiography • Disturbances • Timber Treatments • Ownership, Land Use • Forest Type, Stand Age • Prior land use • All Trees >4 in dbh Measured and Assessed • Location in Subplot • Species, Diameter, Height, Status, Damage, etc

  11. Survey of Forest Invasive Plants Data collected on Subplots Cover estimated for up to 4 invasive species CodeCover 1 Trace < 01 % 2 1-10 % 3 11-50 % 4 > 50% (50-90%) 5 90-100%

  12. FIA Websites Invasive Data and Maps Southern SRS FIA Nonnative Invasive Data Tool • Summary tables by Species by State • County data by subplot and cover of Invasive Plant Species Future Developments • New data will be updated on the 15th of each month • Current data maps and shape-files available

  33. We must get ahead in our projections and know what we will be managing. Have working EDRR and containment strategies and programs. Be real about how we tackle these species by long-view assessments that are multi-species. Perform Cost-benefit analyses. Gain political buy-in at all levels.
