The Finger Lakes Institute (FLI) at Hobart William Smith College has compiled a nice library of information on Aquatic Invasive Species Management. Resources covering milfoil to zebra mussels are available on their web site. There are brochures to aid in in plant identification as well as background research covering invasive species in upstate NY.
Check it out at the link to the FLI web site below:
