Some observations:• “Tens Rule” From Williamson & Fitter (1996) Ecology 77:1661-1666
4) Impacts
Some observations:• “Tens Rule” From Williamson & Fitter (1996) Ecology 77:1661-1666
Only ~10% of imported species escape to wild

Some observations:• “Tens Rule” From Williamson & Fitter (1996) Ecology 77:1661-1666
Only ~10% of imported species escape to wildOf species that make it to the wild, only ~10% become
naturalized

4) Impacts
Some observations:• “Tens Rule”• Measuring impact is complex
What should be measured and how?
4) Impacts
Some observations:• “Tens Rule”• Measuring impact is complex
What should be measured and how?For individual plant, individual species, or multiple species?
4) Impacts
Some observations:• “Tens Rule”• Measuring impact is complex
What should be measured and how?For individual plant, individual species, or multiple species?Over what time frame?
4) Impacts
Some observations:• “Tens Rule”• Measuring impact is complex• Lack of comprehensive data
4) Impactsa) Ecological
Conceptual model: From Walker & Smith in Lukens & Thieret (1997)• Invasive species affect different community & ecosystem
