LAKE GENEVA, Wisconsin — Fifteen employees of the Wisconsin Department of Natural Resources gathered at Big Foot Beach State Park on May 16 to learn more about using injections of systemic pesticides to protect the health of high-value trees at state properties.

Ten Wisconsin State Parks employees and five members of the DNR’s Forest Health team met with representatives of Rainbow Ecoscience and Bartlett Tree Experts to witness a demonstration of best practices for tree injections.

As there is every glorious spring, there has been a flurry of tree planting in Wisconsin. Each little tree, from seed to sapling, is a hope and prayer that we make for the future. But as each reader knows, that future might be many years away.

While you nurture these arboreal miracles, why not take a couple minutes to document the trees in the Wisconsin Tree Planting Map? The map was designed to help track trees planted to advance the state’s pledge to the Trillion Trees Initiative.

USDA Biological Control Facility Seeks Ash Trees To Battle Emerald Ash Borer

Asks Landowners To Donate Infested Ash Trees

The U.S. Department of Agriculture (USDA) is asking Wisconsin landowners for their help. Emerald ash borer (EAB) is an invasive insect from Asia that was first introduced into the United States in 2002. Since its discovery, EAB has caused the death and decline of tens of millions of ash trees. USDA uses ash trees to combat the pest to help preserve and protect the tree species.

Wisconsin landowners have donated live, infested ash trees to USDA’s EAB biological control program. The wood is used to grow EAB’s natural enemies and release them in Wisconsin and 31 other infested States as well as D.C. where they are attacking and killing EAB. USDA needs more ash trees to continue this work and is hoping more Wisconsin residents will consider donating their ash trees this year.

Scroll down to see how communities around the state celebrated Arbor Day in 2023!

Governor Tony Evers attended the village of Germantown’s Arbor Day celebration on Friday, April 28. Village Park and Recreation staff organized the event with help from Wendland Nursery and the Wisconsin DNR. In addition to village staff and leaders, there were approximately 35 elementary students in attendance, all part of the Kids Club (an after-school program at County Line School). DNR Urban Forestry Coordinator Olivia Witthun spoke with the students and presented the community with their 19th annual Tree City USA award. Olivia was assisted by DNR Forestry staff Mike Warnke and Kim Sebastian. The local nursery provided a planting demonstration and gave each student a plant or vegetable to go home with.

In early April, Douglas County became the 53rd Wisconsin county added to the state’s spongy moth quarantine list after a discovery that the invasive insect (formerly known as gypsy moth) had become established in the county.

The United States Department of Agriculture-Animal and Plant Health Inspection Service (USDA-APHIS) and the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) made the determination based on results of a monitoring program of adult moths and other life stages.

This June and July, spongy moth populations are predicted to reach damaging levels in parts of Wisconsin. Populations began to rise in 2020, and this is likely to be the third year of the pest outbreak in some regions of southern Wisconsin.

At present, damaging populations are expected to be most noticeable in southern counties, counties to the north of the city of Green Bay, and in far northern Wisconsin near Lake Superior. Additional areas are likely to have high populations that are more concentrated in size.

Researchers at the University of Wisconsin-Stevens Point are seeking the opinions of Wisconsin’s forestry professionals.

Researchers are conducting an online survey to understand the professional development and training needs of Wisconsin practitioners in fields including forest management, timber harvesting, forest products, and urban forestry. By participating, you will help inform the development of more relevant, accessible, and valuable training opportunities.

The survey should take approximately 15 minutes to complete, and your response is anonymous. Visit this link to participate and share your thoughts in their online survey. The deadline to participate is April 28. 

If you have questions related to this study, please contact Zoe Kaminsky, graduate research assistant, at zkaminsk@uwsp.edu.

Make Plans To Control Spongy Moth Before The Eggs Hatch

Posted on by patricialindquist

Spongy moth (formerly known as gypsy moth) egg masses typically begin to hatch in April as temperatures warm. Each mass that hatches may produce up to 1,000 leaf-eating caterpillars.

Now is a great time to inspect your trees for egg masses and treat or remove any masses within reach. Wisconsin weather has been favorable for this pest over the last three years and populations have grown.
