The Future

  • 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”

Collaborative Action Need to Continue…
