The Maine Department of Agriculture Conservation and Forestry (DACF) has recently verified the first known occurrence of mile-a-minute weed (Persicaria perfoliata) in Maine. This fast-growing invasive vine, native to India, Asia, and the Philippine Islands, poses a significant threat to nurseries, Christmas tree farms, reforestation projects, and restoration areas, as it can smother young plants and trees under its dense growth.

Invasive species like mile-a-minute weed have the potential to cause severe harm to Maine's environment and economy. As part of our commitment to controlling and eradicating this invasive plant, the DACF urges the public to report any potential sightings promptly. If you encounter a vine resembling mile-a-minute weed, please visit the Maine Natural Areas webpage for identification information. If the plant matches the description, we encourage you to take photos, note the location, and report the finding via email to Invasives.MNAP@maine.gov or call (207) 287-7545.

South Carolina has documented its first black and white tegu lizard, a species popular in the pet trade, in Lexington after a SCDNR social media post in May informed the public about the non-native lizard already established in both Georgia and Florida, likely as a result of release or escape. SCDNR staff have been monitoring the situation closely and have received multiple reports since May from Lexington and Aiken counties. No previous reports could be confirmed.

SCDNR asks people to report any sightings of black and white tegus in the wild to Andrew Grosse, grossea@dnr.sc.gov. If possible, please submit a photo, location, and time and date the individual was seen.

The Maryland Department of Agriculture has confirmed that a single adult spotted lanternfly has been found on a trap in the northeast corner of Cecil County near the border of Pennsylvania and Delaware. This is the first confirmed sighting of the invasive species in Maryland, and the department does not believe there is an established population of the pest in the state. If you suspect you have found a spotted lantern fly egg mass, nymph, or adult, snap a picture of it, collect it, put it in a plastic bag, freeze it, and report it to the Maryland Department of Agriculture at DontBug.MD@maryland.gov.

Quagga mussels were found in the Snake River in September 2023. Immediately afterwards, Idaho Fish and Game assisted the Department of Agriculture in their evaluation of potential treatments to eliminate the mussels, and Idaho Fish and Game quantified the fish populations found in the six-mile stretch of river where the mussels were found, and where the treatment would occur. Biologists quickly learned that the treatment caused high mortality in certain species, while others survived quite well.

Giant threats to Arkansas's fish and water are lurking under the surface somewhere right now. The Arkansas Game and Fish Commission needs boaters' help in stopping these terrors before they spread any further. Matt Horton, the AGFC's Aquatic Nuisance Species program coordinator, says 36 aquatic nuisance species have been documented in Arkansas, including plants, fish, mussels and other types of organisms. Some of the more well known species include giant salvinia, silver carp, northern snakeheads and zebra mussels, but these are just a few of the species that can pose significant ecological and economic harm, as well as a risk to human health.

Just like when fighting a virus, Horton says the best plan of attack is to prevent it from spreading to new areas. Here are some ways everyone can fight aquatic nuisance species in Arkansas to keep our waters healthy and accessible for angling and boating enjoyment.

This week, Florida Agriculture Commissioner Nikki Fried and the Florida Department of Agriculture and Consumer Services (FDACS) Division of Plant Industry (DPI), along with the U.S. Department of Agriculture (USDA), announced the eradication of the giant African land snail (GALS) from Broward and Miami-Dade counties. This eradication announcement marks only the second time this pest has been eradicated in the world, both in South Florida. For the past 11 years, the FDACS Division of Plant Industry has worked toward eradication through multiple rounds of visual surveys and inspections, K-9 detector dog surveys and inspections, manual collection and treatment programs. In total, 168,538 snails were collected from 32 core population areas comprised of thousands of properties.

The giant African land snail is a highly invasive agricultural pest, known to feed on over 500 varieties of plants. They also pose a risk to humans and animals by carrying rat lung worm, a parasite that can cause meningitis in humans. Both the USDA and DPI will continue to remain vigilant in their commitments to safeguard American agriculture through surveys, early detection, and rapid response. The public should continue to watch for the snails and report suspects to the FDACS-DPI hotline at 1-888-397-1517.

At its February 2021 meeting, the Florida Fish and Wildlife Conservation Commission (FWC) approved staff recommendations to create new rules to address the importation, breeding and possession of high-risk invasive reptiles. The approved rule changes to Chapter 68-5, F.A.C. specifically address Burmese pythons, Argentine black and white tegus, green iguanas and 13 other high-risk nonnative snakes and lizards that pose a threat to Florida’s ecology, economy, and human health and safety.

The Invasive Plant Management Section funds scientific research projects at Florida's universities to improve the state's invasive plant management programs by finding more cost-efficient control techniques and also insuring these control methods are effective, safe, and environmentally compatible.
