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.

Wisconsin Forestry Center Seeks Industry Input

Posted on by patricialindquist

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

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.

Treat Your Valuable Ash Trees Against Emerald Ash Borer This Spring

Posted on by patricialindquist

By Bill McNee, Forest Health Specialist, Oshkosh, Bill.McNee@wisconsin.gov or 920-360-0942

Property owners with healthy, valuable ash trees are encouraged to treat them with insecticide this spring to protect against emerald ash borer (EAB). The pest is currently the most damaging threat to trees in Wisconsin, killing more than 99% of the ash trees it infests.

Woodpecker damage during the winter is often the first sign that an ash tree is infested. The birds remove pieces of bark while feeding on EAB larvae inside the tree. Insecticide treatment of infested ash trees is more likely to be successful if the trees have low or moderate levels of woodpecker damage.

Now is a good time to consider insecticide protection, because the treatments are typically done between mid-April and mid-May. Ash (in the genus Fraxinus) is the only type of tree that needs protection against EAB. Mountain ash and prickly ash do not need protection because the insect does not attack them.

Ash tree branch in West Allis has been damaged by woodpeckers. Sections of bark are missing, exposing the tree’s light brown wood.

DNR Foresters Partner with LEAF Program to Update Forester Activity Guide

Posted on by kirsten.biefeld

In 2008, LEAF, Wisconsin’s K-12 Forestry Education Program, created a Forester Activity Guide. The intent of the guide was to help foresters lead age-appropriate, interactive, hands-on classroom programs for students in grades K-8 with a minimum amount of advanced preparation. The guide was promoted to foresters throughout Wisconsin and even included as part of programming during new forester orientation.

In fall 2021, LEAF staff, working with Kirsten Held, determined that an update to the guide was overdue. To be certain a new guide would meet the needs of current foresters, LEAF sought input from professionals around the state who have both field experience and an enthusiasm for working with students.

The following DNR Division of Forestry staff partnered with LEAF to create a new and improved Forester Activity Guide: Brooke Ludwig, Eau Claire; Steven Kaufman, Oconto Falls; Kara Oikarinen, Washburn; Scott Mueller, Medford; Sarah Ward, Montello; and Brian Wahl, Fitchburg.

The new Forester Activity Guide builds upon the goals set for the original K-8 guide by including more opportunities for outdoor learning around themes that foresters are frequently asked about: What Do Foresters Do?; Caring for the Forest; Forest Products & Benefits, Tree Planting and Natural Restoration and Fire.

All activities include tips for modifying lessons to urban settings and suggestions on how to use the lessons with learners from grades K-12. Lessons in the new guide all have slideshow presentations that foresters can use if their visits must take place in an indoor setting and require even less advanced preparation than lessons for the original guide.
