2024 Spongy Moth Review

A tree shows high numbers of spongy moth caterpillars, though the majority of the caterpillars have been killed either by virus (hanging in an inverted V) or fungus (hanging in a stretched line, head down). The virus and fungus helped to quell a potential outbreak in many areas of the state in 2024.

As the 2023 spongy moth season ended, there were hopes for a return to colder and wetter conditions in 2024 so that the spongy moth outbreak would decline or even come to an end.

What wound up happening in Wisconsin was the “lost winter,” the warmest since recordkeeping began in 1895. Given this warmth, there were concerns that the widespread spongy moth outbreak would continue for a third consecutive summer, with good caterpillar survival, ongoing defoliation and high rates of tree mortality in already stressed forests.

It takes more than a village to foster healthy forests. More than a township, a city and a county, too. Sometimes, even more than a state.

That’s why the Great Lakes Basin Forest Health Cooperative (GLB FHC) was formed four years ago by Holden Arboretum in Ohio and the U.S. Department of Agriculture Forest Service.

Geographically, the group’s region encompasses an area from New Jersey to Wisconsin. The Wisconsin Department of Natural Resources (DNR) is an active member.

Treatment Of EAB Infestations In Yard Trees

This summer’s detection of emerald ash borer (EAB) in Burnett County means our little metallic friend (or should I say foe?) is now known to be present in all 72 Wisconsin counties.

While EAB has been around for the better part of two decades in Wisconsin, many homeowners are still in the thick of dealing with the fallout of this invasive pest.

Urban Forestry Welcomes Jay Dampier As New IRA Grant Coordinator

Posted on by janness

Jay Dampier joined the Urban Forestry Team on June 3 as the new Inflation Reduction Act (IRA) grant coordinator. This is a federally funded project position that will be overseeing $4 million of federally funded grants awarded to Wisconsin communities, tribes and nonprofits. These IRA funds were allocated to the urban forestry program by the United States Department of Agriculture (USDA) Forest Service in 2023. As part of the Justice 40 Initiative, 100% of the funds will be used to improve the urban forest resources and lives of those living in disadvantaged communities throughout the state.

Upcoming Changes To Three Urban Forestry Regions

Posted on by janness

The boundaries of the Northeast, East Central and North Central DNR Urban Forestry regions will be altered at the end of April to balance workload across the regions better. The changes are:

  • Winnebago, Fond du Lac and Green Lake counties are moving from the Northeast to the East Central region.
  • Waushara and Marquette counties are moving from the Northeast to the North Central region.
  • Forest and Florence counties are moving from the North Central to the Northeast region.

The map included below reflects these changes and will be available on the Urban Forestry Contacts webpage after the changes take effect.

Now that spring has sprung, Wisconsin Department of Natural Resources (DNR) staffers can expect questions from the public about their yard trees.

However, the mission of DNR Foresters and Forest Health staff is geared toward focusing on larger, forested areas, not yard trees. Those questions fall under the purview of the University of Wisconsin-Madison Extension Horticulture Program.

If the 2024 spring and summer weather conditions are favorable for the spongy moth (Lymantria dispar) population, the current outbreak will continue and spread to other parts of Wisconsin. Property owners are encouraged to examine susceptible host trees (including oak, birch, crabapple, aspen and willow) and make plans to manage them.

In summer 2023, Wisconsin saw a record amount of defoliation. State agencies received many calls from property owners urgently seeking a tree care business to control a large caterpillar infestation.

Forest managers planning silvicultural treatments in stands susceptible to spongy moth (Lymantria dispar) – such as those containing many host species, including oak, birch, aspen and basswood – are encouraged to conduct annual egg mass surveys before treatment.

Surveys make it possible to predict if heavy defoliation is likely. If more than 30 egg masses are found in a sample area – a circle with a 37-foot diameter – then heavy defoliation is expected in the spring, and management activities should be altered or delayed until an outbreak has ended.

Now that spongy moth egg laying is complete for 2023, it’s a good time to look for and dispose of the egg masses produced by adult moths over the past two months.

Spongy moth egg masses are tan-colored lumps about the size of a nickel or quarter, and can be found on trees, buildings and other outdoor objects. They may also be found in protected places such as firewood piles and birdhouses.
