Ken Zimmerman, Lone Tree Cattle Company, Bishop, California; Acting Chair, National Invasive Species Advisory Committee; Chair, Range Mgmt Advisory Committee, California State Board of Forestry
8:45 - 9:30Keynote: The State of Invasive Plants & Altered Fire Regimes in American Deserts - A Call to ArmsAn Overview of the five deserts (ecology, fire regimes, etc) and the threats that invasives and wildfires present to the natural and human resources in these ecosystems. Julio Betancourt,USGS
9:30 - 10:00BreakRefreshments provided  
10:00 - 10:30Topic 1: Land Use and Plant Invasions in the American DesertsSummarize the history of plant invasions focusing on an upland invader (cheatgrass) and a riparian invader (tamarisk) describing vectors, colonization, establishment, spread, and impact phases of invasion. Dave Pyke, USGS
10:30 - 11:00Topic 2: Invasive Plants that Alter Fire RegimesPresent information about the dominant invasive plant species that affect wildfire regimes in desert regions (centered on detailed examples of an herbaceous and a woody invader), describe the specific ways that they alter fire regimes and lead to an invasive plant/fire regime cycle, and explain what is necessary to break this cycle. Matt Brooks, USGS

Jeanne Chambers, USFS

11:00 - 11:30Topic 3: Wildfires and Climate ChangeSummarize the predictions for climate change across all deserts and how this will interact to alter the biology of invasive species and future fire regimes. John Abotzglou, San Jose State
11:30 - 1:00 PMLunch Provided
Invited Speakers
Agency Under Secretaries and Hot and Cold Desert Governors Address Attendees
(15-20 minutes each)
Dr. Gale Buchanan, USDA Under Secretary for Research, Education and Economics

1:00 - 1:30Topic 4: Altered Ecosystem Processes: Biogeochemical Cycles, Soil Biology and BiogeochemistrySynthesize current literature on how fire regimes altered by plant invasions affect soil:
• physical
• chemistry
• biology
Edith Allen, UC Riverside
1:30 - 2:00Topic 5: Altered Ecosystem Processes: Watershed Processes and Hydrologic EventsSynthesize current literature on how fire regimes altered by plant invasions affect hydrologic events:
• physical/hydrologic properties
• chemistry
• biology
Fred Pierson, ARS, Cold Deserts

Jeff Stone, ARS, Hot Deserts
2:00 - 2:30Topic 6: Cascading Impacts on BiodiversitySynthesize current literature on how fire regimes altered by plant invasions affect biodiversity in hot and cold desert regions. Address both single species (e.g. desert tortoise, sagebrush endemics) and multispecies (annual plant diversity, general wildlife habitat quality, etc.) Todd Esque, USGS, Hot Deserts

John Rotenberry, UC Riverside, Cold Deserts

2:30 - 3:00Topic 7: Economic and Social Impacts of Desert Fires and InvasivesSynthesize the economic and social impacts fire regimes altered by plant invasions. Mark Brunson, Utah State University - Sociologist

John Tanaka, Oregon State University - Economist

3:00 - 3:30BreakRefreshments provided  
3:30 - 4:00Topic 8: Approaches to Managing Altered Fire Regimes and Their ConsequencesSynthesize the various land management approaches for preventing, or mitigating the effects of, fire regimes altered by plant invasions. This should include some mention of fuels management, fire suppression, and post-fire rehabilitation. Jim Douglas, Assistant Director, Fire and Aviation Bureau of Land Management
4:00 - 4:30Topic 9: With All of the Tools Available, Why Are Invasives and Wildfires Increasing?Describe the limitations in technology, funding, knowledge and then discuss their effects on our efforts to reduce invasive plants that alter fire regimes. Dick Mack, Washington State University
4:30 - 5:00Summary and SynthesisBrief Synopsis of Presentations and reiterating the Workshop tasks. Kurt Pregitzer, UNR
5:00 - 8:00Poster Session
Cash Bar, Hot and Cold Appetizers
"OPEN to all ATTENDEES". All that register a poster can participate. Posters should focus on case histories of "on-the-ground management efforts that work - or don't work". Posters up from noon of day 1 to end of conference.
