Milfoil Inventory Project

Invasive Eurasian Milfoil Inventory and Removal Project.
– Nature Conservancy of Canada (NCC), The Kenauk Institute, and countless volunteers

Eurasian milfoil (Myriophyllum spicatum) is an invasive aquatic plant introduced to North America in the 19th century. Today it’s one of the most widespread invasive plants on the continent and brings with it a suite of negative impacts for humans and ecosystems. Milfoil invades the coastal zone of lakes; impeding swimming, water sports, water quality and biodiversity. It was recently discovered that Papineau Lake has been invaded by milfoil, so in an effort to protect the lake and the rest of the watershed, the Kenauk Institute and NCC conducted an inventory of the lake for the invasive plant and mapped it. During the summer of 2020 Kenauk hosted milfoil experts that trained us on how to effectively remove the invasive plant; going forward the focus will be on removals as well as protecting the lake trout spawning sites.

In 2023 we continued our milfoil removal efforts: 6 large colonies were tarped using 24 tarps and over 1200 sandbags to cover an area of 3,612m2 of milfoil – 9 colonies were also manually removed by divers for a total of 850lbs of milfoil removed from the lake.
