He has had some success. But the success scientists have achieved in reducing the sea lamprey, another invasive species, in the Great Lakes gives him hope that solutions can be found to control Minnesota’s waters or rid them of invasive species. Using chemicals, barriers and traps, sea lamprey numbers have fallen 90 percent since the 1950s. Meanwhile, the invasive species will do a lot of damage in Minnesota, Sorensen said. Zebra mussels could alter ecosystems, affecting game fish. And more invaders are on their way, including the northern snakehead fish — sometimes called the “Frankenfish” because it is voracious, grows up to 3 feet and can survive several days out of water. “Conventional approaches don’t work,’’ Sorensen said. “It’s time to get serious about this.’’ DNR sees merit A research center could potentially develop poisons, parasites or even genetically engineered diseases that would attack the invasive species. Steve Hirsch, Department of Natural Resources director of ecological and water services, said Sorensen’s proposal has merit. The DNR would work closely with a research center. “This would have nationwide significance,’’ Hirsch said. He said that some invasive species research is being undertaken elsewhere but that doing more locally likely would be beneficial. He agreed with Sorensen that deterrent barriers aren’t 100 percent effective, “but they would buy us some time while we develop better control methods,’’ he said. The DNR intends to conduct a research symposium in March to gather researchers who are working on Asian carp to determine what research is being done. Sorensen’s proposal says efforts to control invasive species are stalled by a lack of local resources and expertise. DNR managers “are restricted to imperfect technologies developed at other locations for other reasons,’’ he wrote in his proposal. “This is a critical issue that the state must address, because if we do not help ourselves, no one else will.’’
DNR LAUNCHES NEW PREVENTION EFFORTS IN 2012 TO SLOW SPREAD OF AQUATIC INVASIVE SPECIES (Released January 6, 2012) The Minnesota Department of Natural Resources (DNR) announced today its new strategies to fight the spread of aquatic invasive species across the state in 2012. The efforts take a two-pronged approach: to increase inspections and decontamination of boats at and near water bodies, especially those infested with aquatic invasive species; and to increase awareness that the public must do its part not to spread invasive species. “The DNR cannot be at every boat ramp this summer, making sure boaters, anglers and other water users are not bringing zebra mussels and other invasive species to public waters,” said DNR Commissioner Tom Landwehr. “Our message is these waters belong to everyone – so everyone needs to be responsible for not moving these invaders.” In 2012, the DNR will institute new invasive species check stations, hire more watercraft inspectors, deploy more decontamination units and increase its public awareness efforts – all to stop the spread of zebra mussels and other aquatic invaders. Here is an overview: ROAD CHECK STATIONS A new state law gives DNR authority to operate check stations that require motorists transporting boats, trailers and other marine equipment to be inspected for aquatic invasive species. The check stations, which will begin this year, will route motorists pulling boats 10 or other marine equipment into staging areas, where they will be greeted, and a brief conversation will take place prior to their boats and other water-related equipment being inspected. Among other questions, inspectors will ask where the boat is coming from and how long it has been in the water. If the boat or water-related equipment fails the inspection, or inspectors believe the boat may be carrying aquatic invasive species, the motorist and boat water related equipment will be directed to an area where high-pressure and hot water will be used to decontaminate the equipment. Conservation officers may also take enforcement action if the motorist or boat owner has not Continued on page 11
