A contagious species
  • Full geographic spread in North America is
    broadening
  • Present in Oregon, California, Washington (?),
    New York, Virginia, Michigan

New York, Steven Daniel
California, Esa Crumb
Oregon

Disperses easily
  • Equipment
  • Clothing
  • Pets
  • Wildlife (deer)
  • Water?

4
Invasiveness
  • Enemy Release Hypothesis
  • Roy et al. 2011
  • Evidence of within-species hybridization,
    multiple introductions to western US
  • Rosenthal et al. 2008

5
Landscape invasiontypical process for
false-brome
  • Starts in areas where people and wildlife travel
  • Roadsides, Parking lots, Trailheads
  • Spreads rapidly along roadsides and forest edges
  • Also spreads quickly into closed-canopy forest
  • Spreads more slowly into prairies and pastures
    but facilitated by isolated trees

14
Landscape control strategies
  • Detect and control new and isolated patches
  • Contain large populations
  • Start with reducing seed production or
    eliminating plants in high traffic areas Stop
    the spread!
  • Roads, trailheads, parking areas, hiking trails,
    game trails
  • After containment, move to eradication if feasible

17
Landscape control strategies
  • Establish partnerships, especially with adjacent
    landowners
  • Neighbors
  • Agencies
  • Use existing networks, if possible, to coordinate
  • Example Middle Fork Willamette Watershed Council
    with funding from OWEB, NFWF
  • Coordinated survey across multiple properties,
    outreach and education, control opportunities

18
Landscape control strategies
  • Land management activities
  • Before
  • Eradicate false brome to avoid spreading to other
    sites
  • Clean equipment before entering new areas
  • After
  • Clean equipment before leaving
  • Adopt strict contract language that stipulates
    these actions, with consequences.
  • Public outreach
  • Stop invasions before the start
