Invasive Species

Donate / Volunteer

Invasive aquatic species are a problem throughout the Black Warrior River watershed, especially in reservoir areas and backwater sloughs. These plants are artificially introduced, and once established they tend to out-compete native plant species, covering sloughs, creek mouths. and river banks. The result is altered wildlife habitat, and a hindrance to recreation and navigation. Additionally, these plants often harbor unsightly trash along the river banks and in sloughs. Once established these invasive aquatic plants are difficult to eradicate. Chemical application is not a desirable solution to the problem. The best solution is taking precautions to prevent the introduction of these species into our water resources in the first place.

As shown in this article from The Tuscaloosa News on Smith Lake in the Black Warrior River watershed, releasing nonnative baitfish is a terrible idea:
