1. Group C: Invasive Species Interactions With Other Stressors Q1: Critical Scientific Issues Climate change Drought & extreme weather Increasing CO 2 Fire Multiple invasives and native pests Recreation Pollution Fragmentation Development and oil & gas extraction Transportation corridors Harvesting, thinning, restoration

2. Group C: Invasive Species Interactions With Other Stressors Q1: Scientific Issues Integrated frameworks Drivers vs passengers (MacDougal 2005) Who is the driver? Who is the passenger? Modelling changes in potential native and invasive species distributions (niches)

3. Group C: Invasive Species Interactions With Other Stressors Q2: Critical Management and Policy Issues Increase capacity to prioritize &conduct mgt activities Develop public trust. Improve public support Increase effectiveness of agency collaborations Increase relevancy to stakeholders, decision-makers and funders Improve management efficacy through research findings Understand and reduce management as a stressor Include tribal values and TEK in policy and management Sustain genetic diversity to ensure resilience & resistance

6. Group C: Invasive Species Interactions With Other Stressors Q4: Issues Likely to Become Important by 2040 2 billion more people – increased population stress Understand how to deal with uncertainty Understand impacts of trade and globalization Need increased international collaboration Changes in science expertise and capacity (e.g. long-term research) What impacts will new technologies have? Impacts of changes in ecosystem services

7. Group C: Invasive Species Interactions With Other Stressors Q5: How This Topic can Potentially Connect With Other Topics in Chapter Outline Interactions with other stressors cross-cuts all other topics Other stressors are an uncertainty multiplier To what extent will people focus on climate change or fire and not invasives? Could also be an opportunity.

8. Group C: Invasive Species Interactions With Other Stressors Q6: What are the Gaps in Knowledge and Current Research Models and databases Develop dynamic, spatial models Integrate multiple models and databases Spread models Improve forecasting ability Uncertainty Improve decision-maker ability to handle uncertainty

9. Group C: Invasive Species Interactions With Other Stressors Q6: What are the Gaps in Knowledge and Current Research Ecological data Knowledge of distribution and impacts of native & invasive species Large scale, long-term studies to track changes for mgt use Understand how other stressors change invasibility Integrate human dimensions with invasive species issues social values, costs & benefits, demographics, land-use changes
