14 Irreversible transformation of Sonoran Desert to monospecific grassland Impacts on prominent national parks and conservation initiatives, including land acquisition for preservation Increasing demands & mitigation requirements to protect threatened and endangered species Escalating fire risks & suppression costs in previously fireproof landscape Reduced tourism & property values Impacts of Buffelgrass Invasion

29 Buffelgrass crisis will eventually require aerial spraying of herbicides to slow down spread on remote, steep terrain. This will require community buy-in.

30 Buffelgrass Summit, Feb. 9, 2007, Starr Pass Marriott Resort

31 Minimize spread in areas where buffelgrass not yet established Implement control priorities based on actual & potential impacts Restore treated areas in ways that increase resilience against future invasion In areas where control is no longer feasible, mitigate fire risks to life & property Motivate legislation aimed at sustaining the control effort Create a template for invasive sp mgmt in AZ

41 Perennial C4 bunchgrass from Africa/S. Asia Individuals can live 20 yrs Swollen stem bases allow it to store carbs & survive grazing, drought & fire Apomictic, seeds viable for up to 4 yrs Susceptible to cold Introduced throughout subtropics; escapes readily Fire temperatures >1000°F, >12’ flames Buffelgrass Attributes
