Zombie plant a threat to fish and even swimmers

Prince Edward Islanders are being asked to take extra care when moving their boats around this fall.

The Nature Conservancy of Canada is concerned about the spread of Eurasian water milfoil, also known as zombie plant. The invasive species has been reported at a few sites on P.E.I.

"It's a challenging one to manage," said Andrew Holland, national media relations director with NCC.

"It takes up a lot of space. It grows in ditches and marshes, streams, lakes, shorelines and it spreads quite rapidly, and it replaces and outcompetes native plants."
Milfoil can establish itself in water as deep as 10 metres, and forms thick mats that grow up to the surface, blocking out light for other vegetation. It can become so thick that even fish have trouble getting through it, and it can be a hazard for swimmers who might get caught up in it.

It also creates pools of stagnant water that are ideal for mosquitoes.
