  1. Strategies for Landscape Control and Containment of False-bromeTom KayeInstitute for Applied EcologyCorvallis, Oregon

  2. 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

  3. 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 invasion:typical 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

  6. False brome invasion forest grassland

  7. 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

  8. False brome invasion forest grassland

  9. False brome invasion forest grassland

  10. 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

  11. 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
