Aquatic Invasive Species (AIS) Best Management Practices for Water Access Providers

Minnesota Department of Natural Resources.

These best management practices for water accesses have been developed by the Minnesota Department of Natural Resources in an effort to reduce the spread of aquatic invasive species (AIS). By following these guidelines, providers of public and private boat access facilities can create visible and functional designated areas where boaters can clean and drain boating equipment and conduct other AIS prevention activities.

Aquatic Invasive Species Affirmation
Minnesota Department of Natural Resources.
An affirmation card reminds boaters and nonresident anglers of Minnesota’s aquatic invasive species laws. Watercraft owners and nonresident anglers must read and sign the affirmation during their regular license renewal, then keep it in their possession with their license. The affirmation, enacted by the Minnesota Legislature, is another positive step in the state’s proactive efforts to keep 95% of Minnesota lakes off the infested waters list.
Aquatic Invasive Species Education Project

Maryland Department of Natural Resources.

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.

Best Management Practices for Control of Non-Native Invasives (Jan 2015) (PDF | 1.11 MB)

Montgomery County Department of Parks (Maryland). Park Planning and Stewardship Division.

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.

CAES Announces the Finding of Spotted Lanternfly in Southbury, Connecticut (Oct 15, 2019) (PDF | 60 KB)

Connecticut Agricultural Experiment Station.

The Connecticut Agricultural Experiment Station (CAES) in cooperation with USDA APHIS Plant Protection and Quarantine (PPQ) announce the detection of single live adult spotted lanternfly, Lycoma delicatula, in Southbury, CT. While no other spotted lanternflies were found upon surveying the immediate area, a live insect strongly suggests others may be present within easy transport from somewhere in the region. Additional surveys in the area are planned.

The spotted lanternfly is an invasive sap-feeding planthopper that was discovered in Berks County, Pennsylvania in 2014. It is native to China, India, and Vietnam. It attacks many hosts and has the potential to severely impact Connecticut’s farm crops, particularly apples, grapes, and hops, as well as a number of tree species like maple. Early detection is important for the protection of Connecticut businesses and agriculture. The public is urged to report potential sightings of this invasive pest to ReportSLF@ct.gov. For more information, see the CAES Pest Alert (PDF | 1.9 MB).

Department Announces Updates to Invasive Plant Regulations (Feb 2017)
Maryland Department of Agriculture.
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.
