Invasive plant species can have a negative impact on the health and function of our natural environment, including our streams, wetlands, and lakes. Invasive plants displace beneficial native vegetation, impair water quality, and contribute to streambank erosion. The removal and control of these plant species is very important to improving the health of our aquatic areas.
