These plants are known to be invasive or potentially invasive in Connecticut and are on Connecticut's list of Invasive and Potentially Invasive Plants. They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available. If you find these species: Report your findings immediately to the CT Invasive Plant Coordinator at reportinvasives@uconn.edu.

Recent sightings of a large, non-native land crab along the South Atlantic coast, including in coastal Georgia, are a cause for concern, according to the Georgia Department of Natural Resources’ Wildlife Resources Division (WRD). Blue land crabs are native from Brazil to south Florida and can be as large as 5-6 inches. Sightings recently have been reported well north of the crabs’ native range, including the coasts of Georgia, South Carolina and North Carolina. Multiple reports have been made to Georgia WRD offices.

The public is encouraged to take photos and report sightings of blue land crabs at GeorgiaWildlife.com/ANS. Questions about blue land crabs? Contact a local Georgia WRD office (details at GeorgiaWildlife.com/about/contact#fish).

European green crabs are one of the most widespread invasive marine species on the planet, originally reaching Washington in 1996. When green crab populations grow too large, they compete with other shellfish, disturb the sediment, and destroy the eelgrass that is an important habitat for Dungeness crab and salmon. The U.S. Geological Survey (USGS) is working to increase the effectiveness of Washington’s green crab early detection and rapid response program. Research conducted at the USGS' Western Fisheries Research Center aims to improve native shellfish habitat and limit the spread of European green crabs in coastal waters.

Golden mussel (Limnoperna fortunei), an invasive, non-native freshwater bivalve, was recently discovered in the Port of Stockton by California Department of Water Resources staff while conducting routine operations. This discovery is the first known occurrence of golden mussels in North America. The species poses a significant immediate threat to the ecological health of the Delta and all waters of the state, water conveyance systems, infrastructure and water quality. Please report organisms observed in California suspected to be golden mussels to CDFW’s Invasive Species Program.

Most invasive insects are hidden away for the winter, but you still might encounter them when you split wood, move outdoor furniture indoors, or admire evergreen plants while on a hike.  Learn more about invasive pests you may come across and how to report them.

One of the basic principles of invasive plant management is early detection. To that end, IPAW is sponsoring a reward program to encourage and provide incentive for citizens of the state to look for and report prohibited invasive plants.

Managing invasive species becomes increasingly difficult and expensive as populations of new pathogens, plants, insects, and other animals (i.e., pests) spread and reach high densities. Research over the past decade confirms the value of early intervention strategies intended to (1) prevent invasive species from arriving within an endangered area or (2) detect and respond quickly to new species incursions.

Tracking the establishment and spread of existing and new invasive species is critical to effectively manage invasive species. In addition to standard means of monitoring, the USGS is developing new tools, particularly molecular techniques, to assist in the early detection of invasive species.

The Michigan Invasive Species Program’s new campaign  – “See it. Squish it. Report it.” – reminds Michiganders and visitors of the simple steps they can take to prevent new introductions of spotted lanternflies in the state. f 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 it online to Eyes in the Field. Photos are necessary to verify a report and to aid in identification.
