Regulation of Invasive Plants in Maryland - Comments due by Dec 17, 2012 (Nov 26, 2012)
Invasive Notes Weblog.
These regulations outline the risk assessment protocol and the rules concerning plants that are ultimately ranked as Tier 1 or Tier 2 invaders. No plants have yet been assessed -- this is NOT the plant list, but the regulations that will apply to them when they are assessed.

Destructive Emerald Ash Borer Discovered in Montgomery County (Jun 29, 2012)
Maryland Department of Agriculture.
The Maryland Department of Agriculture (MDA) has detected the invasive, highly destructive emerald ash borer (EAB) beetle in Montgomery County - the seventh county in the state to have a positive identification of the pest. Last summer, MDA concluded that the pest was likely present throughout the western shore and imposed a quarantine on all 14 counties west of the Chesapeake Bay and Susquehanna River, making it illegal to move ash products to the Eastern Shore.

State Highway Administration Pesters Invasive Species with Beneficial Insects (Jun 29, 2012)
Maryland Department of Transportation
SHA, along with the Maryland Department of Agriculture (MDA), is enlisting the help of the mile-a-minute weevil and the purple loosestrife beetle in the epic struggle to control invasive plant species that pose a threat to wetlands, native vegetation and wildlife habitat. Similar programs, which have been successful in New York, Delaware and other states, are using greener methods to control invasive plant species. In Maryland, SHA and MDA have used insects for the biological control of thistle, another invasive weed species.

Didymo Infests Third Maryland Trout Stream (May 7, 2012)
Maryland Department of Natural Resources.
Maryland Department of Natural Resources' (DNR) biologists confirmed the presence of didymo, an invasive algae known to anglers as rock snot or boulder boogers, in Big Hunting Creek in Frederick County. DNR urges all anglers to do their part in helping to stop the spread of didymo to other trout waters. Anglers should remove mud and debris from their boots before entering and soon after leaving streams and use wader wash stations to clean their boots in saltwater before heading off to another body of water. If a wader wash station isn't available or the wash pan of salt water is empty, anglers should disinfect their boots at home. Letting boots and gear dry thoroughly for at least 5 days between fishing trip will also kill didymo cells. DNR also reminds anglers that felt-soled boots were banned in all Maryland waters effective March 22, 2011, to protect and preserve wildlife and their habitats.

Snakehead Invaders Spread to the Rhode (Jul 19, 2011)
Smithsonian Environmental Research Center. Shorelines.
Scientists have discovered a northern snakehead in Anne Arundel County. Biologists from the Smithsonian Environmental Research Center were taking annual fish samples last week when they found the 23-inch egg-bearing snakehead in the Rhode River. Scientists are exploring whether low salinity levels in the Chesapeake Bay allowed the snakehead to travel to Rhode River.

Citizen Science: New Website Launched Making it Easier to Report Sightings of Chinese Mitten Crabs (May 2011)
Smithsonian Environmental Research Center.
Are you a crabber, waterman, or concerned citizen? We need your help to detect and assess the status of Chinese Mitten Crabs along the Atlantic and the Gulf Coasts. Recently a new website, Mitten Crab Watch, has been launched to provide information on the invasion of the mitten crab and to allow users to more easily report catches.

Maryland Invasive Plant Bill Set to Become Law (Apr 6, 2011)
Anacostia Watershed Society.
The invasive plant bill (HB 831) will deal with the the nursery trade of invasive plant species in the state of Maryland.  It will employ a comprehensive science-based risk assessment protocol that will generate a tiered list of the state’s invasive plants.  It will ban the most highly invasive species and includes a provision that will require retailers to post signs, warning consumers of the environmental hazards of these plants. This bill is a much needed measure to address and contribute to curbing the invasive plant species problem from its main root cause without affecting the horticultural industry or the state's budget. Hopefully it will serve as a model for other states in the country.
