Hartbeespoort Dam in South Africa has a new invasive aquatic weed to battle, Salvinia minima. The proliferation of common salvinia, just as water hyacinth came under biological control through the combined efforts is no coincidence. In areas that experience high levels of nutrient inflow (pollution), the control of one aquatic weed opens resources to other
A public boat launch doesn’t necessarily make access to a lake free. There are costs involved in keeping the waters weed free, navigable for recreation and stocked with fish. McDill Inland Lake Protection and Rehabilitation District’s president Krista Olson asks people visiting any lake to utlize the donation boxes. Those donations are very important for
Benefits of Weed Harvesting Dr. Stephen J. Souza Lake Hopatcong Commission Environmental Consultant One of the most obvious management activities of the Lake Hopatcong Commission is the weed harvesting program. Some may view this as a simple “mowing” of the Lake. However, much more is accomplished than simply opening boating lanes and improving swimming. The
Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria, algae, roots, plants, snails, and fungi. Many local farm stores keep the product on store shelves helping to make it the most used, and the most economical algae control available for ponds and lakes. Copper Sulfate is ineffective in the
Intensive in-lake and watershed management caused Kohlman Lake, the northernmost lake in the Phalen Chain of Lakes in Minnesota, to go from a relatively turbid to a clear water state. Aquatic plants responded to the clean waters by growing up to the surface. The change in lake state and a comprehensive water quality monitoring dataset
Keeping aquatic invasive species out of Montana bodies of water, specifically invasive mussels, is very important to protecting the native fish and plant species in the area. Researchers said cleaning, draining and drying boats is nearly 100% effective at keeping AIS out of Montana. That is why boat inspections are required in the state. Seaplanes
An aquatic weed harvester was used to remove macroalgae from Georgica Pond in New York from 2016 through 2018 and on a limited basis last year, an effort to inhibit harmful algal blooms, including toxic cyanobacteria, or blue-green algae. Approval has just been granted for the the mechanical harvester to be operated from June to
In order to stop the destruction of infrastructure by aquatic invasive species, USACE and its partners are using three methods of management: biological, mechanical, and chemical. Each process varies in its effectiveness depending on the species of aquatic plant being treated – leaving the team to rely heavily on data to determine the best method
