CHARLEVOIX — Imagine a wall of tall grasses that reach so high that lake views are obstructed, and that are so invasive as the plant grows, that wildlife leaves the area and native grasses and flowers are crowded out.
This may happen to two Lake Charlevoix waterfront homeowners who refused to allow trained volunteers to enter onto their property to treat an invasive plant known as Phragmites (frag-MY-teez).
The two part-time Boyne City residents were the only homeowners around Lake Charlevoix that did not give permission, according to the Lake Charlevoix Association that conducted the work to reduce the Phragmites from around the lake.
There is more than one species of Phragmites, most of which are not invasive. However the species, Phragmites australis, is a problem because it grows and spreads so fast.
People are asked by the DNR not to try to manage it without training because they could inadvertently spread the plant and its seeds.
Phragmites australis is insidious in its takeover of shorelines. Eighty percent of the plant is contained below the ground in a dense mass of roots that can penetrate the soil to a depth greater than six feet, according to the Michigan Department of Environmental Quality. The plants range in height from six-to-16-feet and have horizontal roots that produce new shoots that continue until the roots exceed 60 feet in length.
Approximately 40 volunteers received training from the state after which they surveyed the entire shoreline of Lake Charlevoix and Round Lake to identify stands of Phragmites so the plant could be treated with an herbicide. The treatment was conducted in September 2009.
