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) Impacts a) Ecological Conceptual model: From Walker & Smith in Lukens & Thieret (1997) • Invasive species affect different community & ecosystem processes
