A closer look at how Eurasian milfoil and chemical treatments are harming aquatic life Flint Lake on Valparaiso’s north side is in trouble. Invasive aquatic weeds, especially Eurasian milfoil, have become so overgrown that they’re even interfering with fish population surveys. During a recent Department of Natural Resources (DNR) survey, biologists had to stop two
Lake Shawnee has been identified time and again as one of the most idyllic locations in Shawnee County, Kansas, leading county commissioners to invest heavily in the area in recent years with new walking paths and other features. But maintaining that beauty, and more importantly, what’s under the water, can be challenging and at times
It’s only found in 14 Minnesota lakes at this point, but starry stonewort has the potential to cause lots of harm, and fast. Recent research shows that the macroalgae has the potential to be the high-impact invader in Minnesota lakes that many already fear it is. It warrants the high prioritization that public agencies and
Across the warming globe, a mass exodus of tens of thousands of species is transforming the distribution of biodiversity — and challenging fundamental tenets in conservation policy and science. In recent years, scientists have documented countless species shifting their ranges toward the poles, higher into the mountains, and deeper into the seas in response to
Conservation officials hope that a new herbicide treatment being considered for use in Cocasset Lake in Massachusetts this season may prove an antidote to a mushrooming vegetation problem afflicting local lakes and ponds. ProcellaCOR was recommended for use in Cocasset Lake by Joseph Onorato, an aquatic specialist with Water & Wetland LLC of Upton, which
The Adirondack Park Agency (APA) is using an aquatic herbicide at two points along Lake George in New York State. At both sites, the problem is growth of Eurasian Watermilfoil, an invasive plant species that grows quickly in water bodies it’s tracked into. The APA conducted monitoring and said the herbicide eliminated all traces of
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
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
A highly invasive aquatic weed has been discovered in a number of ponds in the Animas Valley in Colorado, putting the heat on to eradicate it before it enters the Animas River and, potentially, Lake Nighthorse. The invasive weed aggressively outgrows and outcompetes native aquatic plants. It can then clog irrigation systems and ponds, and
Pentwater Lake Improvement Board President Joe Primozich recently issued an update on changes going on in overall health of Pentwater Lake in Michigan. Primozich said according to Progressive AE, the Grand Rapids company that monitors the lake vegetation, the aquatic invasive water milfoil has now changed to the hybrid form. “This means that it has
