The state of Minnesota is home to a wide variety of water birds that dwell in rivers, lakes, and ponds. One of the most prominent lakes in the metro area is Lake Minnetonka. Lake Minnetonka is home to many different types of animals, from bugs to fish to birds.
Effects of Aquatic Weed Removal on Water Birds
Several of the water birds featured in today’s blog today have a diet that consists of aquatic plants and algae. So you may be wondering, “how does aquatic weed removal affect these birds’ diet?” The short answer is that it doesn’t!
Here at Waterfront Restoration, we value an eco-friendly and chemical-free method of weed removal. As a company, we utilize SCUBA by-the-root weed removal to clear lake home properties of weeds. While we are clearing weeds off the lakefront of private properties, most of the weeds removed are invasive and not part of a water bird’s diet. By removing these invasive weeds, we are also helping non-invasive weeds have a better chance of survival. During our service, we also protect native MN weeds that benefit the ecosystem. To protect these weeds we trim them low to the ground rather than remove them by their root structure. As a company, we value maintaining a balanced ecosystem by utilizing a natural approach to weed removal.
Although weeds are being removed from private properties, there are still plenty of weeds in the lake for water birds and other creatures.
