PORTLAND PRESS HERALD • July 28, 2025
An invasive aquatic plant first identified in southern Maine two years ago is now confirmed across southern and western parts of the state, and officials and local groups are taking steps to keep it from spreading farther. Swollen bladderwort, which forms dense mats on the water’s surface and can change ecosystems and hinder recreation, has been found on eight Maine waterbodies, including Tilton Pond in Fayette, where it was discovered two years ago and has since worsened, making it harder to swim and boat. aAboater using Tilton Pond’s now-closed public launch was likely to blame for the infestation. Keeping the plant from hurting more waterbodies in Maine will take diligence.
