Five Aquatic Invasive Species of Concern to LECC

Curly Leaf Pondweed [small amounts found & treated in Edward]

Curly leaf pondweed is an invasive aquatic plant that can form dense mats, obstructing boating and other recreational activities. It can rapidly spread and dominate the water body, making it difficult for native plants to thrive.
