Critical Needs • Prevent NIS Invasions • Limit dispersal • Detect Invaders • Manage invaders
Critical Research • Detect NIS • 2.Measure impacts - Spatial, temporal and ecological patterns of NIS distributions • 3.Limit invasions - Discover processes limiting NIS invasions • Predict the future

Controlling Invasions 1. Survey, early detection and rapid response 2. Limit Dispersal: Education, legislation regulation 3. Reduce vulnerability: Conservation, management 4. Mitigate impacts: Planning, management 5. Extirpate
