An army of invaders is marching north from Bay City. Tim Engelhardt wants to stop them in their tracks. The invader is phragmites, a giant, invasive reed that already rings most of Saginaw Bay, growing more than 10 feet tall and crowding out native plants, animals and views of the water.
Engelhardt, an AmeriCorps volunteer, is the invasive species coordinator for Huron Pines, a Northeast Michigan conservation group headquartered in Grayling.
