Hydrilla, considered one of the world's most invasive aquatic plants, has been detected for the first time in Michigan. The Department of Environment, Great Lakes and Energy confirmed two small populations of the plant in adjacent private ponds on residential properties in Berrien Springs in Southwest Michigan.

The small patches of hydrilla (Hydrilla verticillata) were discovered during routine monitoring following treatment for another invasive plant, parrot feather, which was found in the pond in 2020. Both species are prohibited in Michigan, meaning it is unlawful to sell, possess or import them into the state, and both are on Michigan’s invasive species watch list due to their potential environmental threat. Any suspicious aquatic plants should be reported as soon as possible to EGLE-WRD-AIP@Michigan.gov. Include close-up photos and provide the location of the detection in your report. More information on identifying and reporting invasive aquatic plants can be found at Michigan.gov/Invasives.

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.
