The Army Corps of Engineers is proposing a plan to stop silver and bighead carp moving from the Mississippi River basin into the Great Lakes.

Cheryl Nenn with Milwaukee Riverkeeper calls the proposal a starting point, not a solution, because multiple aquatic invasive species are threatening both the Great Lakes and the Mississippi River basin.

Dogs are extremely good at sniffing things out. Mequon Nature Preserve decided to take advantage of  the canine skill and brought on Tilia, the first on-staff conservation dog in Wisconsin.

One of her trainers is Kathy Hatch. The day I visited, she had been busy hiding several plants amidst tall grasses outside the preserve.

Researchers who work in wetlands in Michigan are taking a new approach to invasive plants. Instead of removing plants like phragmites and switchgrass, they’re harvesting them. They say these plants are a threat to biodiversity, but they can benefit farmers and even power homes.

Roy Norton is Consul General of Canada in Chicago. Wisconsin is one of three states, along with Illinois and Missouri, in his purview.

This week the Consul General is visiting communities around Wisconsin. Much of his visit involves strengthening business ties between the state and Canada.

But Monday, Norton was in Milwaukee at the UW-Milwaukee School of Freshwater Sciences, discussing another key issue – invasive species plaguing the Great Lakes.

A species of earthworms that is known to "act crazy, jump and thrash" is jumping and thrashing  its way across the state.

The worm goes by many names, including crazy worm, jumping worm and snake worm. It is officially known as the Amynthas agrestis and was identified at the UW Arboretum in Madison in October of 2013. Since then, it has turned up in multiple locations around the state, including Milwaukee.

Silver carp DNA was discovered in the Fox River, a tributary of Lake Michigan.

Great Lakes advocates have been fretting for years, about the potential invasion of Asian carp. This week the Asian Carp Regional Coordinating Committee released its updated plan to keep the beast at bay.

The Army Corps of Engineers issued a long-awaited report about ways to keep Asian carp out of the Great Lakes.  

A single positive sample for Silver Carp showed up in Sturgeon Bay near Door County’s Potawatomi State Park.

A new study cautions that even a small number of carp would be enough for the invaders to begin colonizing  the Great Lakes.

It turns out that the health of forests has quite a bit to do with the health of the lakes.
