The fight against invasive plant species in Wisconsin’s forests, woods and natural areas got a big boost over the airwaves in June.

WISC-TV (Channel 3 in Madison) produced a news feature on invasives that included an interview and tour with Wisconsin Department of Natural Resources (DNR) invasive plant specialist and Natural Heritage Conservation representative Mackenzie Manicki.

The Wisconsin Department of Natural Resources (DNR) Forest Health team joined with the DNR Office of Communications to produce an instructional video aimed at helping large landowners and land managers in the fight against spongy moth.

The video, less than 2 minutes in length, shows how to conduct a survey of spongy moth egg masses in the fall. With that information, people can predict how much damage to expect from the caterpillars in the spring, giving them time to make advance plans for the most effective control options.

Many pine stands across central and northeast Wisconsin are being impacted by the change from high levels of precipitation to extreme drought that has occurred over the last 5-7 years.

Drastic or sudden changes can be particularly stressful to trees of all species, but especially to pine stands that prefer well-drained soil types.

Watch For Spongy Moth Caterpillar Diseases

With this spring’s weather bringing above-average rainfall across most of Wisconsin, we will likely see moderate to heavy mortality of spongy moth caterpillars at many locations this summer.

Last year, the statewide May-June period was the third-driest since recordkeeping began in the late 1800s, according to the NOAA National Centers for Environmental Information. As a result, the effectiveness of the caterpillar-killing fungus, Entomophaga maimaiga, was limited. Spring 2024 is noticeably wetter, and thus, increased effectiveness of E. maimaiga is likely.

Andrea Billings insists that she doesn’t do all that much volunteering.

Two species of teasel are present in Wisconsin: common teasel (Dipsacus fullonum) and cut-leaved teasel (Dipsacus lacinatus). Although they are known today as invasive plants, their Latin names speak to a useful history.

The species name of common teasel (fullonum) comes from “to full,” a step in woolen clothmaking that involves using water and agitation. Teasels, native to Europe, were introduced to North America in the 1700s to be used in this manner by textile processors. The stiff and sturdy flower heads of teasel were used to comb the surface of damp cloth to give it a fluffier finish. Continue reading “Teasing Out Invasive Teasels” →
