The goal of this project is to raise awareness about invasive species and to turn that awareness into action to prevent and to manage current and future invasions. The project consists of lesson plans and corresponding hands-on items designed to teach the story about invasive species. Each lesson plan has been aligned with Next Generation Science Standards, Common Core Standards, and Maryland Environmental Literacy Standards. Lesson plans in each module include activities for Grades 3-12.

A destructive, invasive beetle that kills ash trees, the emerald ash borer (EAB), has been confirmed in Delaware, making it the 28th state to have found the insect, the Delaware Department of Agriculture announced today. Delaware will be added to a federal quarantine already in 27 other states restricting the interstate shipment of all ash wood and wood products - ash nursery stock, green lumber, waste, compost and chips - as well as hardwood firewood of all species.

Natural Resources Stewardship staff (NRS) has determined that many non-native invasive plants (NNIs) known to present a significant threat to the quality and biodiversity of the natural areas occur in this 37,000-acre park system. To support the park mission to steward these lands, Montgomery County Department of Parks has prepared fact sheets for park managers and maintenance personnel with easy-to-read information about mechanical and chemical control methods for several terrestrial NNIs.

One of the most invasive weeds in the world is beginning to make its way into north Mississippi, announced the Mississippi Forestry Commission (MFC). "Cogongrass was introduced to Mississippi as a new forage crop, however, it is not palatable for livestock, not even goats will eat it," Bozeman said. "It also failed as an erosion control plant because it was too weedy. With no native competition or consumers, cogongrass spread rapidly throughout the Gulf South." There is widespread cogongrass infestation in south Mississippi, but the MFC is starting to see and get reports of the weed moving into the northern part of the state. If left unchecked, cogongrass could become a statewide problem.

Bozeman wants landowners in north Mississippi to be on the lookout for cogongrass on their property and the notify the MFC if they suspect the invasive weed has taken root. "The Mississippi Forestry Commission can offer assistance to landowners in north Mississippi who have cogongrass on their property," said Bozeman. "We can also come out and help landowners determine if what they are seeing is cogongrass or not." For more information and to fill out the program application, visit the Cogongrass Control Program. If you suspect you have cogongrass on your property, call your local MFC forester to come do a site visit.

The Delaware Department of Agriculture (DDA) announced today that they expanded the spotted lanternfly quarantine to include all portions of New Castle County north of the Chesapeake and Delaware Canal. This is due to recent detections of established populations outside of the initial quarantine zone enacted in February 2019 that included eleven zip codes. "This expansion is necessary in our attempt to eradicate, control, and prevent the spread of spotted lanternfly in Delaware and to surrounding states," said Secretary of Agriculture Michael T. Scuse. The spotted lanternfly is a destructive invasive plant hopper that attacks many hosts including trees, shrubs, orchards, grapes, and hops. For more detailed information regarding the quarantine, permitting, treatment, or to report a sighting of spotted lanternfly, visit the Delaware Department of Agriculture’s dedicated spotted lanternfly webpage or call the dedicated spotted lanternfly hotline at (302) 698-4632.

A Notice of Final Action for the Maryland Invasive Plant Regulations was published in the Maryland Register on Friday, February 3. These regulations went into effect February 13. The updated regulations add a total of four new species to the Tier 1 and Tier 2 lists established by the original invasive plant regulations (April 2016). Weed risk assessments are ongoing, and additional plant species will be added to the lists through the regulatory process as they are completed and approved. These science-based assessments are the foundation for decisions regarding a plant’s invasive status in the state. Full assessment reports are available on the Maryland Invasive Plants Prevention and Control website.
