Arkansas Game & Fish Commission.

Anglers and hunters and other boaters who use the state's waterways are being reminded by the Arkansas Game and Fish Commission's Fisheries Division of a new regulation that took effect Jan. 1, 2021, requiring all boat drain plugs to be removed before and during trailering of vessels to and from access facilities on lakes, rivers and streams. A similar boat plug regulation was already in place in 21 other states to help stop the spread of aquatic nuisance species, and the new AGFC rule was part of an extensive list of regulations recommended by the Fisheries Division and approved by the Commission in 2020, to take effect beginning Jan. 1. Aquatic nuisance species such as silver carp, giant salvinia, zebra mussels and others continue to spread across waterbodies in Arkansas, and the AGFC has as its mission a responsibility to put mechanisms in place to slow the spread.

Arkansas Department of Agriculture.

The Arkansas Department of Agriculture is pleased to announce the release of the newly created Arkansas Feral Hog Handbook, a guide to resources available in Arkansas to assist with feral hog control and eradication. The handbook includes contact information, websites, and brief explanations of the resources offered by state and federal agencies and other entities. "The Arkansas Feral Hog Handbook was made possible through a grant funded by the United States Department of Agriculture's Natural Resources Conservation Service. We appreciate their partnership and the information provided by other Feral Hog Eradication Task Force members to make the handbook a comprehensive educational resource for Arkansans," said Arkansas Secretary of Agriculture Wes Ward.

The handbooks are being distributed to the public at locations throughout the state with assistance from partner organizations, including the Arkansas Association of Conservation Districts, University of Arkansas Cooperative Extension Service, Arkansas Game and Fish, and Arkansas Farm Bureau. Copies of the handbook can be requested at lori.scott-nakai@arkansas.gov. An online version (2020; PDF | 4.48 MB) is also available.

Michigan Department of Natural Resources.

The Michigan departments of Natural Resources and Agriculture and Rural Development today announced the addition of beech leaf disease to the state's invasive species watch list. Invasive species on the watch list have been identified as posing an immediate or potential threat to Michigan's economy, environment or human health. These species either have never been confirmed in the wild in Michigan or have a limited known distribution. Beech leaf disease is associated with the microscopic worm Litylenchus crenatae, a nematode that enters and spends the winter in leaf buds, causing damage to leaf tissue on American beech and European and Asian beech species. Infestations result in darkened, thick tissue bands between leaf veins, creating a striped effect on the leaves, leaf distortion and bud mortality. Trees weakened by leaf damage become susceptible to other diseases and can die within six years. Beech leaf disease has not been found in Michigan. The disease was first discovered in Ohio in 2012. Since then, it has been identified in seven eastern states and Ontario.

Maryland Department of Natural Resources.

The Maryland Department of Agriculture has confirmed the first spotted lanternfly hatch of 2020. The first instar nymph of the season was reported by a department employee while surveying for the pest in the upper northeast corner of Cecil County near the Pennsylvania border.

See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information. For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.

Michigan Department of Natural Resources.

The governors of Illinois and Michigan today agreed to work jointly to protect the Great Lakes from invasive Asian carp species. Gov. Gretchen Whitmer and Gov. JB Pritzker today announced an intergovernmental agreement between the Illinois Department of Natural Resources (IDNR) and the Michigan Department of Natural Resources (MDNR) which allows Illinois to use up to $8 million in funds appropriated in 2018 by the Michigan Legislature to support the pre-construction engineering and design (PED) phase of the Brandon Road Ecosystem Project. Further strengthening the path forward, the State of Illinois also signed a separate PED agreement with the U.S. Army Corps of Engineers for the initial Brandon Road design. The state will serve as the non-federal sponsor, agreeing to help fund design of a portion of the project and to further advance full project design efforts to approximately 30 percent completion.

The Brandon Road Lock and Dam in the Chicago Area Waterway System near Joliet, Illinois, is a critical pinch point for keeping bighead, silver and black carp – the invasive Asian carp species of greatest concern – out of the Great Lakes. The Brandon Road project would install layered technologies including an electric barrier, underwater sound, an air bubble curtain and a flushing lock in a newly engineered channel designed to prevent invasive carp movement while allowing barge passage.

Michigan Department of Agriculture and Rural Development.

The Michigan Department of Agriculture and Rural Development (MDARD) is asking freight carriers, warehouse workers and delivery drivers to be on the lookout for invasive spotted lanternfly after the United States Department of Agriculture (USDA) confirmed dead spotted lanternfly insects were found in Michigan in recent weeks. While the specimens found were dead, these cases demonstrate one of the many ways this insect could find its way into the state. There is no evidence of established populations of spotted lanternfly in Michigan.

If you find a spotted lanternfly egg mass, nymph or adult, take one or more photos, make note of the date, time and location of the sighting, and report to the Michigan Department of Agriculture and Rural Development, MDA-Info@Michigan.gov or call MDARD's Customer Service Center, 800-292-3939. If possible, collect a specimen in a container for verification. For additional information on identifying or reporting spotted lanternfly, visit Michigan.gov/SpottedLanternfly.

Montana Department of Agriculture.

The Montana Department of Agriculture (MDA) has issued an emergency quarantine order to protect against the introduction and spread of the emerald ash borer (EAB), a destructive wood-boring beetle that has already killed millions of ash trees in North America. The order was motivated by the removal of federal domestic quarantine regulations by the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS). "It is important that we remain vigilant and do everything in our power to make sure that the emerald ash borer doesn’t find a way into Montana," said MDA Director Mike Foster. "This quarantine order protects the green ash woodland resources in eastern Montana that provide habitat for many wildlife species as well as economic benefits to livestock producers and rural communities."

Montana’s emergency quarantine order restricts EAB from entering the state in any form, as well as the movement of live ash trees, parts of ash trees capable of harboring live EAB, and any other articles determined potentially hazardous. MDA will accept public comment regarding the quarantine order until February 26, 2021.

Montana Fish, Wildlife, and Parks.

New this year, nonresidents launching watercraft in Montana must purchase a Vessel AIS Prevention Pass.  

  • The fee for motorboats is $30 and applies to all motorized watercraft that is registered in another state our country.
  • The fee for nonmotorized watercraft is $10 and applies to rafts, kayaks, drift boats, catamarans, and sailboats that nonresidents bring into Montana.
  • The Vessel AIS Prevention Pass expires Dec. 31 and is not transferrable between vessels.

Boaters are reminded that all watercraft coming into Montana from out of state must be inspected prior to launching. Anyone transporting watercraft must stop at all open watercraft inspection stations they encounter. To find a watercraft inspection station or to learn more, go to CleanDrainDryMT.com or call the FWP Aquatic Invasive Species Bureau at 406-444-2440.

Michigan's Invasive Species Program.

If your leisure-time plans include boating or fishing in Michigan, recent changes in Michigan’s Natural Resources and Environmental Protection Act (NREPA) may affect you. Beginning March 21, watercraft users in the state are required to take steps to prevent the spread of aquatic invasive species. Also, anyone fishing with live or cut bait or practicing catch-and-release fishing will need to take precautions to limit the movement of invasive species and fish diseases.

Michigan Department of Natural Resources.

For landscapes plagued by autumn olive or entangled in oriental bittersweet, a new website offers help identifying and managing woody invasive plants like these. WoodyInvasives.org, developed by the Woody Invasives of the Great Lakes Collaborative, contains a wealth of information about how to distinguish woody invasive species from similar beneficial plants, an interactive map showing how these species are regulated by Great Lakes jurisdictions, detailed management approaches and noninvasive woody plant ideas for gardeners and landscape designers. "We developed the WIGL Collaborative website to help people learn to identify the woody invasive plants around them and to feel empowered to start controlling them on their properties or in their favorite green places," said Clair Ryan, coordinator of the Midwest Invasive Plant Network, the organization leading the effort.

Wisconsin Department of Natural Resources.

Wisconsin's recently revised aquatic invasive species (AIS) management plan is now final and available for use by the public after receiving approvals from the National Aquatic Nuisance Species Task Force. Wisconsin last completed an AIS management plan in 2002. Wisconsin's AIS management plan serves multiple purposes, including maintaining Wisconsin's eligibility for funding and directing the AIS efforts of the DNR and partner groups. The new plan also introduces an invasion pathway management approach that will help Wisconsin systematically limit how invasive species move into and throughout Wisconsin. The plan can be downloaded here (PDF | 3.89 MB).

Rhode Island Department of Environmental Management.

Trying to reduce the spread of invasive species in Rhode Island waters, the Department of Environmental Management (DEM) has amended the state's Freshwater Fisheries Regulations to prohibit the transport of any plant or plant part into or out of any Rhode Island waterbody on any type of boat, motor, trailer, fishing supplies, or gear. The new regulation carries a $100 fine for each violation. "Many of the aquatic invasive plants in Rhode Island can reproduce from just one small plant fragment and do not need entire root systems to successfully establish in a new spot," said Katie DeGoosh-DiMarzio, Environmental Analyst with DEM's Office of Water Resources. "Cleaning off every bit of plant from recreational gear used at one pond is essential before visiting another — this includes boats, kayaks, canoes, motors, trailers, paddles, jet skis, fishing gear, waders, water tubes, and anchors. These efforts help combat the spread of aquatic invasive species in Rhode Island waterbodies."

Rhode Island Department of Environmental Management.

The Department of Environmental Management (DEM) is asking Rhode Islanders to monitor their beech trees for signs of leaf damage from Beach Leaf Disease (BLD). Early symptoms of BLD include dark striping on the tree's leaves parallel to the leaf veins and are best seen by looking upward into the backlit canopy. Drastic leaf loss occurs for heavily symptomatic leaves during the growing season and may appear as early as June, while asymptomatic and mildly symptomatic leaves show no or minimal leaf loss. BLD was detected in the Ashaway area of Hopkinton, Rhode Island, in 2020 and in coastal Massachusetts. Before these findings, the disease was only known to be in Ohio, Pennsylvania, New York, and Connecticut.

Because of the seemingly random nature of disease in Rhode Island, DEM encourages homeowners and forest landowners to monitor their beech trees and report any suspected cases of BLD on DEM's Invasive Species Sighting Report webpage. Although BLD is relatively new in the U.S. and information is limited, links to additional information about the disease and photos are posted on the Division of Forest Environment's Current Threats page. If people have further questions, they should contact a licensed arborist or email Nancy Stairs, forestry program supervisor in DEM's Division of Forest Environment, via Nancy.Stairs@dem.ri.gov.

Maryland Department of Natural Resources.

Spotted lanternfly is a threat to Maryland and the U.S. The Maryland Department of Agriculture issued a quarantine October 28, 2019 in an effort to contain the invasive species in Cecil and Harford counties after the spotted lanternfly was spotted in Cecil’s northeastern corner and along Harford’s northern border. See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information.

For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.

Ohio Department of Agriculture.

A population of the invasive Spotted Lanternfly (SLF) has been found in Mingo Junction, Ohio just south of Steubenville, along the Ohio River. The initial report came from a resident who spotted a dead adult SLF on a commercial building on October 19, 2020. When Ohio Department of Agriculture (ODA) Plant Pest Control inspectors arrived, they were able to capture five live adult SLF in trees located nearby. ODA has been working with the United States Department of Agriculture, Ohio Department of Natural Resources, Ohio State University Extension, and the Ohio Grape Industries Committee to do visual surveys, insect trapping, and outreach in the region.

The public is the first line of defense against the SLF. If you believe you have seen an SLF in your area, you can easily report a suspected infestation by going to ODA’s Spotted Lanternfly Information Page and filling out a suspected infestation report. You may also call the Plant Pest Control Division at 614-728-6400.

Rhode Island Department of Environmental Management.

The Rhode Island Department of Environmental Management (DEM) is announcing that two exotic species of Asian and Eurasian ticks have been detected for the first time on Block Island. It was confirmed by DNA and morphological characteristics that they are ticks not previously found in Rhode Island. Dr. Danielle M. Tufts identified the tick species Haemaphysalis longicornis and Haemaphysalis punctata when studying ticks on Block Island this summer.

Haemaphysalis longicornis, also called the Asian longhorned tick, was first detected in the United States in 2017 in New Jersey. Haemaphysalis punctata is native to Europe and has not been previously detected in a natural setting in North America. H. punctata is sometimes known as the "red sheep tick" in its native range. The center of its distribution is the southern half of Europe, including England, and there are some established populations along North African coastal areas. The finding on Block Island is notable because this tick is not known to exist outside of its home range.
