Oswego, NY, October 11, 2011 - This three-part series explores the impacts of aquatic invasive species. Public awareness of aquatic invasive species and their negative impacts on the environment and recreation is on the rise. Anglers, landowners, recreational boaters and others who enjoy our lakes and streams have felt the impact of some invasive species already. Learning to recognize invaders before they overwhelm an area is a crucial part of reducing their impact. Understanding native species, their role in the environment, and the threat of invasive species to them is equally as important.
