I forwarded this thread to the Exotic Species Coordinator here at DES and she requested that I post the following message:
Anyone who’d like to have a specimen from the lake identified for verification of whether or not it is native or invasive can simply take a digital picture of it with a camera or cell phone and email it to me at
Amy.Smagula@des.nh.gov. I will reply back with an identification, and if it’s invasive I’ll follow up on location information/etc.
