For over a decade, lakes across Northern Wisconsin have spent staggering sums of money attempting to control Eurasian water milfoil with herbicides. The Lower Eagle River Chain of Lakes Commission, formed in 2007 specifically to tackle this invasive species, is a case in point. Eurasian water milfoil grows aggressively, uprooting native vegetation, disrupting aquatic habitats,
Elodea is a plant commonly found in aquariums that, if released in the wild, will dominate certain lake or river habitats, choking out native vegetation and altering the food web at all levels. It increases sedimentation rate, allowing more sediment to settle out of the water. And it can decrease the dissolved oxygen concentration in
Lake Hallie Lake Association is making some headway in the war they’ve been waging against the hybrid watermilfoil weed. First discovered in Lake Hallie in 2005, watermilfoil is an invasive aquatic plant that has an aggressive tendency to form a thick mat-like layer as it floats on the water. If left unchecked, this plant can
The Massachusetts Department of Conservation and Recreation is aiming to reduce invasive plant species in Lake Whitehall in a plan that calls for herbicides and mechanical harvesting. The reservoir has extensive growth of “exotic nuisance aquatic vegetation,” including fanwort and variable-leaf milfoil, according to a report by ESS Group, a firmed hired by the state.
Aquarius Systems was featured on a National Geographic Cable Channel program broadcast in the United States on April 2nd and 5th, 2003. The Swamp Devil Aquatic Vegetation Cutter (formerly known as the Cookie Cutter) has been used on Lake Victoria since 1998 to help control dense mats of water hyacinth. A film crew from National
Fall has barely begun and the Lakes Area community is already preparing for next year’s battle against the invasive curlyleaf pondweed. The weed caused navigational issues on the lake this past season as it clogged boat motors and jammed dock lifts. The Iowa Department of Natural Resources, local government entities, area protective agency representatives and
An aquatic weed believed to be salvinia molesta, which grew only along the shoreline in January, has multiplied so fast it now covers the entire surface of the water at Lakewood residential community, Pemulwuy, Australia. The lake and its surrounds were home to an abundance of wildlife including ducks, pelicans and a pair of black
Center Lake and Clearwater Lake Association are trying to combat the starry stonewort with and aquatic weed harvester this summer. In an effort to use fewer chemicals in this Missouri lake, a weed harvester will be used on most of the lake to cut and remove the starry stonewort and the algae. Aquatic herbicides will
Trapa natans is native to Western Europe and Africa and northeast Asia, including eastern Russia, China, and southeast Asia to Indonesia. Trapa natans was first introduced to North America in the mid- to late-1870s, when it is known to have been introduced into the Cambridge botanical garden at Harvard University around 1877. A decade later
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
