MACROPHYTE (AQUATIC PLANT) SURVEYS

High-quality macrophyte populations in lakes are needed to use


 

nutrients within the water for their growth. Due to the use of nutrients by macrophytes, lakes are cleaner and healthier because algae cannot readily use the nutrients.

In addition to in-lake water quality sampling, macrophyte surveys can provide further insight into the function of the ecology of the lake. Identifying high-quality macrophyte populations are important to understanding the ecology of the lake, but performing macrophyte surveys allow staff to identify any invasive species of macrophytes such as Eurasian Watermilfoil and Curly Leaf Pondweed. Invasive species tend to overpopulate water resources, out-compete native species, die back early and release nutrients, and in-turn create poor aesthetics.
