  14. The Future Collaborative Action Need to Continue… • Continued Progress on Ballast W ater Control • I ncreased Focus on I nvasive Species  Lessons to date…  Eradication is very difficult ( prevention is key)  Education is key to prevention and spread  Address all vectors ( live bait, live food & aquarium trades; flooding; etc – aquatic invasive species are not just about ballast w ater and artificial canals • I ncreased I nvestm ent in Habitat Restoration • Continued Vigilance on Air Em issions and W ater “Run Off”
