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.

Vilas County has the dubious distinction of becoming the first new Wisconsin county in 2023 to have a discovery of emerald ash borer (EAB).

EAB continues to spread into areas of northern Wisconsin. The first Vilas County detection was in the town of Lincoln. Additional infested trees have since been found in the town of Cloverland and the city of Eagle River. Continue reading “Emerald Ash Borer Found In Vilas County”

Effects Of Winter Take Toll On Trees

Winter damage is one of the most commonly reported tree issues in early spring. The damage may be minor, such as off-color needles that are quickly replaced, but could be as severe as partial- or whole-tree mortality.

Winter desiccation occurs when conifers begin photosynthesizing on warm, windy days in late winter or early spring. Conifers may dry out in these conditions if they use their stored water and cannot replace it because the ground is still frozen.

Applying Directly To The Forest Service For Inflation Reduction Act Funds

The Urban and Community Forestry (UCF) Inflation Reduction Act (IRA) Notice of Funding Opportunity (NOFO) has been announced. Please see the USDA press release here.

Overview:

The Forest Service is making up to $1 billion available in Urban and Community Forestry competitive grants for investments that:

  • increase equitable access to urban tree canopy and associated human health, environmental, and economic benefits in disadvantaged communities
  • broaden community engagement in local urban forest planning
  • improve community and urban forest resilience to climate change, pests and storm events through best management and maintenance practices

Report Tree-Of-Heaven To Help Monitor For Spotted Lanternfly

Spotted lanternfly (Lycorma delicatula) is an invasive insect that threatens a variety of plant species, mostly woody plants. It has not yet been found in Wisconsin, but it is steadily moving toward us from the eastern United States. Both juvenile (nymphs) and adult spotted lanternfly feed by sucking sap from the stem, branches, twigs and leaves of host plants. This weakens the plant and can contribute to the plant’s death. Because spotted lanternfly impacts a wide variety of agricultural crops (like grapes and hops), nursery crops (like roses), and hardwood trees (like maple, walnut, willow, and poplar), it is a high priority pest in Wisconsin.

Wisconsin Forestry Center Seeks Industry Input

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.

Protect Oaks During Spring Clean-up

With the arrival of spring, the Wisconsin Department of Natural Resources (DNR) recommends protecting oaks from the often-fatal oak wilt disease by refraining from pruning, cutting or injuring oak trees from April through July.

The highest risk period for oak wilt introduction to a new site is in spring and early summer. Pruning and cutting oaks exposes living tree tissue beneath the bark to potential infection. The disease rapidly kills trees in the red oak group and weakens those in the white oak group.

Sap-feeding beetles spread the disease between oaks by carrying oak wilt spores from infected trees or firewood to fresh, exposed tree wounds. Healthy oaks and freshly cut oak stumps can become infected as quickly as 15 minutes after a wound is made from a pruning cut or broken branch.

Eight Applicants Receive DNR Urban Forestry Grants In Second Round Of Funding

The DNR Urban Forestry Grant program awarded $108,220 to eight Wisconsin communities for urban forestry projects during the second round of our 2023 funding. Most of the funding ($104,920) was originally reserved for the Catastrophic Storm Grant program but was not needed through the winter months. The rest of the funding ($3,300) came from underspent grants.

The following communities will receive the funds:

  • Village of Allouez, $17,783.00
  • Town of Beloit, $11,804.80
  • Forest County Forestry & Recreation, $3,007.38
  • Heckrodt Wetland Reserve, $5,581.97
