Clean water, dam decay are sea lamprey control challenges

A U.S. and Canadian control project has knocked back the invasive species that prey on fish by 90 percent.
But researchers are trying to address a recently increasing population.

Parts of Ohio will be treated to slow the spread of the destructive gypsy moth early this spring.

Take a look at this map. Cover the title, key and footer. It looks as if someone had a blank map of Michigan and began splattering paint across it. It’s like a work of art. But when the title of the map is revealed, it becomes obvious that all those pretty colors are actually different types of wells strewn across Michigan’s mitten.

The Nature Conservancy has named the round goby one of the five “usual suspects” invading the Great Lakes basin. Round gobies are native to the Black and Caspian seas, but have found their way into the Mississippi River as well as Lake Michigan. These fish have a heightened ability to sense water movement, allowing them to feed in the dark. Round gobies feed on native fish and their eggs, and have a “blood vendetta” against zebra mussels, according The Nature Conservancy. These gobies can grow up to 10 inches in length and somewhat resemble an overgrown tadpole with black, gray or brown skin.
Most people who live in the mitten state have fond memories of time spent at one of the Great Lakes. Those memories are what fuel The Great Lakes Book Project.

The Nature Conservancy has named Eurasian Ruffe, a fish native to northern Europe and Asia, as one of the five “usual suspects” in the Great Lakes basin. This fish has invaded northern Lake Michigan and feeds on native fish eggs. It has sharp spines on its fins making it difficult for predators to catch and eat, giving it the nickname, “Dagger Fin.”
Eurasian Ruffe are generally just under a half a foot in length and have an olive or golden-brown color.
Beach closure data shows improvement in the short term. A recent study of sediments indicate that in the longterm water quality has declined.
As osprey populations continue to increase, so do the issues that they face in a changing environment.
Experts are spreading the word that extreme caution needs to be taken concerning the birds’ nests on cell phone and powerline towers.
Here’s a reminder of Great Lakes beaches in warmer times. This plant is the federally and state-protected Pitcher’s thistle, which is also known as a dune thistle. The photo was taken last summer by habitat restoration specialist Terry Heatlie at Bois Blanc Island in north Lake Huron between Michigan’s Upper and Lower Peninsulas. The Pitcher’s thistle is native exclusively to the Great Lakes region, according to the National Fish and Wildlife Service. It was added to the government’s list of threatened species back in 1988.
Reuse, waste reduction, fuel 10-year decline. The state has almost enough space for three decades of trash.
