Aquatic Plantings

Aquatic plants play a key role in maintaining and enhancing the ecological balance

Aquatic plants serve an important purpose in an aquatic environment. They play a key component in maintaining and enhancing the ecological balance in ponds, lakes, wetlands, rivers, and streams. Beneficial aquatic plants have many values including filtering nutrients and toxic chemicals, stabilizing shorelines and providing important fish and wildlife habitat. Wisconsin Lake & Pond Resource sells and installs a number of aquatic plant species.

Provided is a list of beneficial aquatic plants offered. Ecological values and a description are included for a majority of the plant species.
