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.

The Michigan departments of Natural Resources and Agriculture and Rural Development recently confirmed the presence of invasive beech leaf disease in a small, private woodlot in southern St. Clair County. Beech leaf disease, not previously known to be in Michigan, 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, European and Asian beech species. Trees weakened by leaf damage become susceptible to other diseases and can die within six to 10 years after initial symptoms.

DNR and MDARD encourage monitoring for any signs of the disease. If you suspect you have found a symptomatic tree, take one or more photos of the infested tree, including close-ups of affected leaves; note the location, date and time; and report it in one of the following ways:

• DNR Forest Health Division: Email DNR-FRD-Forest-Health@Michigan.gov or call 517-284-5895.
• Use the Midwest Invasive Species Information Network (MISIN) online reporting tool.
• Download the MISIN smartphone app and report from your phone.

Black carp, which are an invasive fish species in North America, are now known to be established in the wild in parts of the Mississippi River basin. A new study co-authored by the U.S. Geological Survey (USGS) is the first to identify an established population—meaning they are naturally reproducing and living to adulthood— of wild black carp in any location across the U.S.

When a black carp is captured in the wild, it can be reported to the USGS Nonindigenous Aquatic Species database. That tool compiles information on and can be used to track the status of other aquatic invasive species as well. The USGS is involved in many invasive species projects across the U.S. and its territories. Learn more by visiting the USGS Invasive Species website or the USGS Invasive Carp section.

The Galapagos National Park Directorate (GNPD) is partnering with CABI and the Charles Darwin Foundation (CDF) to help protect the iconic Galapagos Islands from an invasive blackberry (Rubus niveus). This non-native plant was introduced in 1968 and is causing serious problems for local biodiversity and agriculture. It is now considered one of the worst weeds affecting the islands.

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).

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the detection of box tree moth (BTM) (Cydalima perspectalis) at two residences in Clinton located in Lenawee County. Although not a threat to Michigan’s natural resources, extensive feeding from box tree moth can lead to significant defoliation and death of ornamental boxwood.  In May 2021, potentially infested boxwood plants were shipped to retail locations in several states including six in Michigan. The pest was then identified in three of the six Michigan facilities. It is not known whether the box tree moth populations detected in Clinton are linked or if the pest entered the state through another pathway.
