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.
