Chances are, when you look at a body of water, you don’t give a second thought to the plant life floating on the surface or sticking out of the shallows. Depending on your point of view, they could be “pretty” or just a bunch of “weeds.” The fact is, these plants (and the ones you can’t see under the surface) are an important part of the aquatic ecosystem. Some plants are native to the region and extremely beneficial. Others are invasive species that don’t belong there.

Native Species: The Good Guys

Bodies of water naturally evolve over time and eventually create a balance of plant and animal life. The plants put oxygen in the water and provide nutrients and hiding places for fish to flourish, attracting other wildlife to the area. This provides home owners numerous opportunities for recreational activities that they value.

Invasive Species: The Bad Guys

Invasive species come from out of town, so to speak. They don’t work their way into a regional ecosystem gradually over decades, but barge in unannounced. And you can’t stop them from coming. They arrive by air (bird droppings), land (hitchhiking on wildlife) and water (bait buckets, boats and fishermen’s boots). All it takes is a few seeds to launch an incursion. Even plants from a lake in the same county can be threatening.

Why It Matters

Can a few plants really make a such a difference? Here’s what two government agencies have to say about Invasives.

The National Invasive Species Information Center says “…these plants…grow aggressively, and have a high reproductive capacity. Their vigor combined with a lack of natural enemies often leads to outbreak populations.”

According to the Florida Exotic Pest Plant Council, “These population explosions can have catastrophic effects, out-competing and displacing native plants and disrupting naturally-balanced native plant communities. Invasive aquatic plants can completely fill a water body, driving fish and wildlife from the area.”

It doesn’t sound like something you want to happen in your back yard, does it?

What You Can Do

One thing you cando is to wash down boats and gear when going from one body of water to another. It’s kind of like using hand sanitizer to minimize infection. But, as we pointed out before, Invasives can still find you.

What Not to Do

Whether you live on a pond, lake or waterway, the worst path of action is to grab a commercial herbicide off the shelf and declare war on any plant in sight. Not only do some of these products contain chemicals that are harmful to wildlife and humans, a scorched earth policy will deprive the body of water of the plants that filter pollutants from the rainwater that flow into it, provide cover for wildlife and fish, and add an element of beauty that frames the shoreline. It will also upset the delicate natural balance that is best for the ecosystem.

Call the Pros

Regular monitoring and preventative maintenance are required to ensure invasive species don’t establish themselves and get your body of water into serious trouble. Unfortunately, the average person is not qualified to do it.

Most plants look very much like another to the untrained eye. In addition, you can’t readily see what is happening beneath the service of the water, where many issues begin. Besides, even if you could identify an unfamiliar plant, what would you do about it?

The best suggestion is to call in a professional water management team like Clarke. Preparing a survey of the plant life in your particular water habitat and taking action against aggressive species is the only sure way to protect the natural plant balance in your body of water. Our Control Consultants know the difference between Hydrilla verticillate and Myriophyllum spicatum and any number of other harmful plant species. Regular preventive inspections can catch any invasive plant life before they can do irreparable harm.
