How can learning be enhanced outdoors? What does a tree canopy at a “green” school look like? Can an outdoor classroom be an effective learning environment?

Edison Middle School in Green Bay is exploring outdoor STEM learning opportunities thanks to partnerships with DNR Urban Forestry, American Transmission Company (ATC) and LEAF K-12 Forestry Education. The plan to create an outdoor classroom grew from a discussion Urban Forestry Coordinator Tracy Salisbury had with ATC staff looking for opportunities to give back to communities. ATC’s interest in funding STEM education in their communities was a natural fit for the DNR’s goal to increase tree canopies at schools.

For the third consecutive year, damage from introduced basswood thrips (Thrips calcaratus) is significant in some areas of northeast Wisconsin, especially Forest County.

Introduced basswood thrips are tiny, invasive insects that feed inside tree buds in early spring. The feeding causes leaves to deform when they expand, looking like they suffered frost or wind damage.

Keep An Eye Out For Beech Leaf Disease

Forest owners and land managers should look for beech leaf disease (BLD) this summer, a destructive beech tree disease in the United States.

The disease is primarily found on American beech (Fagus grandifolia) but can also be found on ornamental species such as European, Oriental and Chinese beech (F. sylvatica, F. orientalis and F. engleriana). Although it has not yet been found in Wisconsin, recent discoveries of the disease in Michigan and other nearby states highlight the continued importance of monitoring BLD’s expansion. There is potential for BLD to move into Wisconsin as the eastern portion of the state overlaps with the native range of American beech.

Brood XIII periodical cicadas (Magicicada spp.) rest on a tree at Big Foot Beach State Park in Lake Geneva on June 12, 2024.

Scattered twig death, commonly known as “flagging,” was recently observed on several trees at Big Foot Beach State Park in Walworth County, where large numbers of 17-year Brood XIII periodical cicadas (Magicicada spp.) were present. This flagging is likely present in other localized sites in southern Wisconsin that experienced high numbers of cicada emergences.

The University of Wisconsin-Madison Insect Diagnostic Lab’s Periodical Cicadas in Wisconsin webpage has more information about the periodical cicada outbreak.

Invasives And Imposters: Native Look-Alikes To Know

Native plants benefit Wisconsin wildlife, pollinators and ecosystems. However, many resemble harmful invasive species, making identifying problem plants in the woods challenging.

It is important to learn a few key characteristics to unmask the imposters and correctly identify the invasive plants. With a little study and practice, you can quickly differentiate between these perplexing pairs.

Five Years Later, Effects Of Derecho Remain

Over the night of July 19-20, 2019, Mother Nature carved a massive swath of destruction through northern Wisconsin.

Today, after years of hard work cleaning up after the massive derecho windstorm of ’19, local foresters, work crews and landowners have only begun to understand the breadth and depth of the damage as they process the lessons learned.

In many areas, the recovery work remains incomplete. Some of that forest damage will never receive direct attention.

Oak Moth Outbreaks May Have Peaked In North

A three-year-long outbreak of oak leafroller moth and oak leaftier moth—two native, early-season oak defoliators—continued this spring in northern Wisconsin, leaving behind tens of thousands of acres of oak-dominated forest with scattered, widespread defoliation.

Partially defoliated, thin and yellow-tinted crowns were visible across portions of Barron, Rusk, Sawyer and Washburn counties, as well as areas in Florence, Forest, northern Marinette and Vilas counties.

Reminders About Spongy Moth Quarantine

The state Department of Agriculture, Trade and Consumer Protection (DATCP) works with the U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS) to enforce a spongy moth quarantine in Wisconsin, with the goal of limiting the spread of the spongy moth to new, uninfested areas.

The quarantine now covers 53 of Wisconsin’s 72 counties. The quarantine regulates woody nursery stock, Christmas trees, firewood, logs and outdoor household items. Quarantine regulations apply to businesses and private citizens.

As of early July, we have seen a mix of live and dead caterpillars and tree defoliation that is typical of a late-stage spongy moth outbreak. Reports of defoliation have been received as far north as Florence County.

Recent aerial surveys in southern Wisconsin spotted defoliation in the same general areas as in 2023, but the defoliation has generally been less intense this year. Information for northern Wisconsin has yet to be made available. Refoliating oaks, growing a second set of pale-looking leaves, were seen in Walworth County in early July.
