Organisms targeted by NISA are categorized as aquatic nuisance species, including in particular zebra mussels and Eurasian ruffe.To extend upon NANPCA, NISA authorizes regulation of ballast water, a key factor in the spread of aquatic invasive species; funding for prevention and control research; regional involvement with the Aquatic Nuisance Species Task Force; and education and technical ...
NISA authorizes regulation of ballast water, a key factor in the spread of aquatic invasive species. To minimize the spread of invasive species in U.S. waterways, EPA and the Coast Guard developed plans to regulate the concentration of living organisms discharged in the ballast water of ships. [11] The Coast Guard issued ballast water ...
Japanese stiltgrass (Microstegium vimineum) invasion of a forest in Greenbelt, Maryland. Numerous non-native plants have been introduced to Maryland in the United States and many of them have become invasive species. The following is a list of some non-native invasive plant species established in Maryland.
Maryland's waterways contain many exotic species of fish and other water life. The streams' biodiversity includes fish, birds, salamanders, mussels, ten turtle species, and over 100 species of fish. Plants and vegetation surrounding the aquatic habitats provide nutrients, shelter for animals, temperature regulation, and erosion abatement.
Aquatic plant harvesting is often done to clear waters for navigation and recreation, as well as for the purpose of ridding the environment of invasive plant species. However, this aquatic plant management style can also have negative effects on the environment such as harming non-target plants and animals, increasing turbidity, and potentially ...
The Pennsylvania Fish and Boat Commission has several new regulations coming into effect Jan.1 aimed at reducing the spread of invasive species. New regulations starting Jan. 1 ask Pa. boaters ...
The database tracks details on over 500 invasive species throughout coastal North America. SERC coordinates with the United States Geological Survey , which has developed a similar database for freshwater invasions, and has worked with marine centers in other nations to study marine invasions.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
