A newly released scientific paper raises fresh concerns about the potential for grass carp to invade the Great Lakes and do significant damage. The fight to prevent Asian carp from reaching the lakes has focused mostly on bighead and silver carp, which could unravel food chains because they gobble huge amounts of plankton.
Great Lakes advocates are meeting in Washington, D.C., this week to lobby for funding of environmental projects and to discuss strategies for dealing with challenges such as invasive species. More than 100 people from the eight-state region are attending the Great Lakes Commission’s semiannual meeting and other activities.
University of Minnesota researchers have confirmed a new invasive fruit fly in Minnesota. A single adult female known as the African fig fly was discovered in a bait trap in September. The trap was located in Hastings and was being used for annual monitoring of another invasive fruit fly, the spotted wing Drosophila. The university says the new fly specimen was officially identified this week by the U.S. Department of Agriculture.
The U.S. Army Corps of Engineers and the White House Council on Environmental Quality are hosting a public meeting in Bloomington to discuss options for preventing the spread of Asian carp and other invasive species between the Great Lakes and Mississippi River basins.
The number of zebra mussels on Lake Mille Lacs has dropped this year for the first time since they were found in 2005. Minnesota outdoors officials say a survey this week found about 1,070 zebra mussels per square foot.
The Sherburne National Wildlife Refuge is a recreation destination. But this summer, some of the biggest animals there are cows. About an hour north of the Twin Cities, the refuge is more than 30,000 acres of oak savanna and wetlands. But some invasive plant species are threatening to change this habitat. So they’re trying a new way to control the undesirable plants, letting cows eat them.
The Asian Carp Regional Coordinating Committee outlined a $6.5 million plan on Thursday that includes expanding efforts to remove the invasive fish from the Upper Illinois River below a set of electrical barriers meant to keep them from reaching Lake Michigan.
Minnesota is now the second state in the U.S. to use dogs to sniff out zebra mussels.
Researchers studying water samples from the Mississippi and St. Croix rivers for fragments of Asian carp DNA say they found little evidence of bighead and silver carp in Minnesota.
At least some Asian carp probably have found their way into the Great Lakes, but there’s still time to stop the dreaded invaders from becoming established and unraveling food chains that support a $7 billion fishing industry and sensitive ecosystems.
The University of Michigan is establishing a research program designed to bring more scientific credibility to the federal government’s billion-dollar battle to clean up the Great Lakes, officials said Tuesday.
Experts will be gathering in La Crosse this week to share the latest information on invasive species.
The University of Minnesota Raptor Center will head to the Galapagos island of Pinzón next week to in a continuing effort to help the endangered Pinzón giant tortoises and hawks.
A member of Congress from Michigan says the U.S. Army Corps of Engineers will not meet a legal deadline for completing a plan to preventing Asian carp from invading the Great Lakes.
The Minnesota Department of Natural Resources says a man got more than he bargained for when he transported zebra mussels hitching a unique ride.
