States and Canadian provinces that border the Great Lakes and St. Lawrence Seaway invest millions of dollars to track and control invasive species. A new tool developed by the Great Lakes Commission promises to make that task a little easier. Current State’s Kevin Lavery reports.

Invasive species pose a real threat to the Great Lakes. But not all of them are easy to spot. Current State talks to Joan Rose, co-director of MSU’s Center for Water Sciences, about the risk that invasive viruses could pose to the ecosystem. 

If the Great Lakes put up “most unwanted” posters, they’d be plastered with pictures Asian carp, zebra and quagga mussels, and sea lamprey.

An Ovid resident has some giant guests in her yard who've worn out their welcome.

Giant hogweed is a towering plant that can grow as tall as 14 feet, with white flowers spreading up to two feet in diameter.  While it’s nice to look at, giant hogweed is a highly toxic plant that can cause severe burns and even blindness.

Botanist Peter Carrington is the man Michigan State University is sending to uproot this invasive species.  He’s the assistant curator of the W.J. Beal Botanical Garden at MSU.
