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.

The U.S. Department of Agriculture (USDA) is asking Wisconsin landowners for help in the battle against emerald ash borer (EAB).

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.

The USDA is asking Wisconsin landowners to donate live ash trees infested with EAB to support USDA’s biological control program. The staff will use the wood to rear EAB’s natural enemies, which will then be released in Wisconsin and 31 other EAB-infested states and Washington, D.C.

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

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.

WisBURN: A Place For All Things ‘Burning’ In Wisconsin

Posted on by ryoungfluur

By Catherine Koele, DNR Wildfire Prevention Specialist

For southern Wisconsin, fire season is well underway. For others in the north? Well, unfortunately, it may be June before some of the snow piles completely melt. But, it’s never too early to be thinking about spring fire season. To gear up, the DNR launched an update to WisBURN—the place to get current fire season information throughout Wisconsin.

Fire danger and DNR burn restrictions can change daily. WisBURN can help keep you informed!

Many people have come to recognize the Wisconsin DNR’s fire danger and burn restrictions webpage over the years. It draws in nearly 700,000 page views every year from outdoor enthusiasts, rural property owners, hunters, farmers, local governments, and even the media. 

Earlier this year, the Division of Forestry officially launched the latest rendition of WisBURN. Users take note—the web address has changed, seamless redirects are in place, and it’s now considered a web-based, interactive mapping application. The updated web address is now: apps.dnr.wi.gov/wisburn

Annual Property Implementation Plans Available

Posted on by ryoungfluur

Each spring, Wisconsin State Forests develop Annual Property Implementation Plans (APIPs) and Monitoring Reports identifying the major scheduled and completed forest and habitat management treatments, recreation and infrastructure developments and other property management actions. You are invited to review the APIPs online and direct questions and comments regarding the plans to the respective property manager. 

All planned treatments and developments in APIPs are approved and consistent with property master plans previously developed using public input. Annual Property Implementation Plans do not include routine maintenance or minor actions including mowing, building maintenance, inventory or field surveys.

Oak Harvesting During A Cold Spring

It’s April, but in much of Wisconsin the weather doesn’t seem to have gotten the message.

You may be wondering if the oak harvesting restriction that started on April 1 (south of the tension zone) and will start on April 15 (north of the tension zone) might be pushed back due to unusually cold temperatures.

Even with unusually cold springs, we remain consistent with the same general messages: “Stop pruning in April” and “Avoid harvesting in April (south of the tension zone).” We do this for the following reasons:

  • It is difficult to spread the word in a timely manner about when to begin the restrictions. Often when spring comes late, it arrives suddenly; in those cases, before we know it, we’ve entered the high-risk period.
  • We want to be consistent in stressing the messages of the existing oak harvesting guidelines, so that the public is aware of them.
