Aquatic Invasive Species Starry Stonewort
Heidi Bunk, a water resources management specialist with the Wisconsin Department of Natural Resources, said while the long-term effectiveness of hand pulling the invasive species starry stonewort is still being evaluated, it can be advantageous because it allows for the removal of starry stonewort without harming native species in the way chemical treatments might. She

Chicago Sanitary and Ship Canal
The U.S. Army Corps of Engineers is taking some innovative, and perhaps unusual, steps to keep Asian carp (the silver and bighead carp in particular) from infesting the Great Lakes. In the next several years several layers of protection will be used to thwart the arrival of the carp by way of the Chicago-area rivers

Natural and man made debris floating on the waters surface
West Coast beachcombers have treasured the rare sightings of Japanese glass floats; spherical buoys strung together to aid fishermen in managing their catch. It was once thought that these translucent orbs took nearly a decade to reach the U.S.–traveling up to 8,000 miles of open sea. But in 2011, 5 million tons of debris was

Aquatic Invasive Species Eurasian Watermilfoil
New research has found that hurricanes in the United States are dispersing invasive species across the country. Fueled by climate change, hurricanes are becoming more frequent and intense, research shows; as a result, extreme storms are carrying and scattering hundreds of invasive species such as Asian swamp eels and zebra mussels into new regions of

Chemical Treatment of Lake
Lake managers might be hurting native aquatic plants – instead of helping them – when they use chemicals to control invasive plants on entire lakes. New research by Wisconsin DNR Lakes and River Team Leader Dr. Alison Mikulyuk shows native plant communities can struggle when chemicals are used to target invasive Eurasian watermilfoil. It appears

In the past 100 years, the planet has warmed in the range of 10 times faster than it did on average over the past 5,000. In response, thousands of species are traveling poleward, climbing to higher elevations, and diving deeper into the seas, seeking their preferred environmental conditions. This great migration is challenging traditional ideas

Pewaukee Lake was formed in 1838 when a dam was constructed along the Pewaukee River and the wetland was flooded. It combined with Snake Lake to form the 2,500 acre Pewaukee Lake. For 40 years – 1945 to 1985 – the sanitary district used herbicides, including 2-4-D for 17 years, in an attempt to control

Discharging Ballast Water on Cargo Ship
According to a Fish and Wildlife study, almost 80 percent of non-native species found on the West Coast were first sighted in California. You might have heard about ballast water. Cargo ships fill their holds with seawater to stay balanced, but that water can also carry invasive species. Since 1999, ships have been required to
