Invasive

They're the villain cousins of invasive plants... The spiny water flea, the Emerald Ash Borer, the Rusty crayfish and Rocksnot. Each either in New Hampshire or threatening to do so and harming not only the water, plants and land but indigenous animals, plus they have not natural predators. We'll look more closely at these invasive fish, insects and mollusks and what's being done to combat them.
