What you "can" and "can't do" in public waters, The best way to prevent problems in public or private water bodies is with prevention. Don't put any nonnative plants, fish, pets or other organisms into any waterbody. Check boat trailers, boat hulls and propellers. Rinse and remove aquatic plants or invertebrate hitchhikers such as snails. Don't dump aquarium contents in lakes, channels or other water bodies. Replace invasive and other non-…, What you can do:, Identify your plants using the Illegal Aquatic Plants of SC booklet distributed by SCDNR. You can use mechanical devices such as weed rakes or cutters. You can cover the bottom with weed mats. You can manually pull up problematic vegetation. You can hire a mechanical harvester. E-mail the SCDES Aquatic Nuisance Species Program for information about aquatic weed problems in public waters:…, What you can't do:, Never dispose of or plant invasive species in any waterbody. (Laws prohibit the transport or spreading of certain species of plants!) Never stock grass carp into a public waterbody. (It's against the law, you could be fined!) Don't remove grass carp from a public waterbody. (It's against the law, you could be fined!) Never apply herbicides to a public waterbody.

ANS TASK Force
Successful management of non-native aquatic invasive species is one of the most pressing issues in the field of natural resources management in the country. Impacts include both dramatic changes in plant and animal community structure and dynamics and economic impacts to manage use of our water resources. The S.C. Department of Natural Resources recently completed a three-year Aquatic Nuisance…SCDES Local Offices
Why Manage Invasive Species
Management decisions based on science have made plant management against invasive species now an essential function of government. Refusal by plant managers to allow hydrilla or other invasives to become the dominant aquatic plant in the state is not just for the benefit of homeowners and industry, but also for the benefit of our native aquatic plants and other native animals, for the benefit of…, What are invasive (nuisance) aquatic plants and why are they a problem?, Invasive non-native aquatic plants are those which have the potential to hinder the growth of beneficial aquatic plants, to interfere with flood control, irrigation or navigation, or to adversely affect the public welfare or the natural resources of this state. Some of the more common invasive aquatic plants in South Carolina include hydrilla, water hyacinth, giant salvinia, water primrose,…, What is being done?, Nuisance aquatic plant populations are being managed using an integrated management approach to prevent them from reaching problematic levels. Integrated management utilizes biological, chemical and manual control techniques to maintain control of various nuisance and invasive species. At the same time efforts are made to minimize negative impacts on native vegetation. In certain instances,…, We've learned that management:, Reduces the environmental impact of noxious weed species; Allows greater use of our waters; Uses less herbicide; Greatly reduces the overall costs; Creates greater biodiversity; and Promotes public confidence and cooperation., Wildlife, waterfowl and fish need aquatic plants:, Misconceptions have developed over the years, based on erroneous information, as to what types of aquatic plants are beneficial to all wildlife. A prime example of this is the information that is spread about ducks. For thousands of years, ducks and other migratory water birds have come through South Carolina as temperatures drop in the northern United States and Canada. They fed on eelgrass (, Vallisneria, ), pondweeds (, Potamogeton, ), duck potatoes (, Sagittaria, ) and other plentiful, native, aquatic plants. Then, in the 1970s non-native hydrilla (, Hydrilla verticillata, ) was introduced and invaded several of South Carolina’s lakes and rivers, quickly displacing and greatly reducing the abundance of eelgrass, pondweeds, duck potatoes and other plant duck foods. During that period of time, with hydrilla on the increase and ducks having to consume hydrilla instead of preferred native plants, confusion has developed among duck hunters and others about the value of…, Among the native aquatic plants that are especially important to wildlife, fish, ducks and other water birds in South Carolina are:, the submersed plants of these genera: Ceratophyllum, Chara, Najas, Potamogeton, Ruppia, Utricularia, and Vallisneria; the tallish emersed plants of these genera: Carex, Cladium, Cyperus, Distichlis, Echinochloa, Eleocharis, Eriocaulon, Fimbrystilis, Juncus, Leersia, Panicum, Paspalum, Polygonum, Pontederia, Rhynchospora, Sacciolepis, Scirpus, Spartina, Typha, Xyris, Zizaniopsis, and Zizania; and…, The bottom line, Native plants are just as able to provide the same beneficial functions as do the invaders, and native plants have provided these benefits for eons before the invaders came. For example, eel grass, pondweeds, bladderwort, the submersed sagittarias and others are some native plants that provide underwater plant surface area for fish food (those periphyton and small animals that attach to plant…Environmental Assistance Conference
