A contagious species

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

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

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

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
