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.

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.

Laws and regulations at the state (Michigan) and federal level are designed to stop the introduction and spread 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.

This curriculum provides background information, hands-on activities, worksheets and links to additional sites that teachers can utilize to engage students in formal and informal real-world settings. While some of the lessons build on previous learning, most of the lessons can stand-alone. IPM can be used as a theme in the classroom for an entire year, or as enrichment to regular classroom activities.
