Property owners with healthy, valuable ash trees should consider treating 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. Now is an excellent time to consider insecticide protection because the treatments are typically done between mid-April and mid-May once leaves begin to return.
Treatments on already-infested ash trees are more likely to be successful if the trees have low or moderate levels of woodpecker damage.

Typically, gypsy moth egg masses hatch in April as temperatures warm. Now is a great time to do an egg mass inspection to look for unknown infestations and treat or remove any masses within reach. Each mass can result in 500 to 1,000 leaf-eating caterpillars.
Egg masses are tan-colored lumps and vary from about the size of a nickel to a quarter. They can be found on many outdoor surfaces such as tree trunks, the undersides of branches, buildings, rocks, fences, retaining walls, firewood piles and picnic tables.

Stalactiform stem rust, which occurs in the Lake States and Canada on jack pines, was recently found in western Monroe County. Before this discovery, the only place I have seen stalactiform stem rust in Wisconsin was Adams County in the mid to late 1990s.
Rust diseases can be identified by the galls’ shape and location and by cankers present on the trees. On jack pine seedlings and saplings, stalactiform stem rust can cause elongate swellings on branches or the main stem (trunk).

The DNR’s Forest Products Services team hosted a webinar in June 2020 that highlighted some of the positives of building with wood and explored the state of Wisconsin’s forest resources. To expand on that basic message, we are working on a series of future webinars that will address more specific themes within the broader theme of building with wood.
To best assess which topics potential attendees are most interested in learning about, we kindly ask that you fill out the survey linked below. We would very much appreciate you taking the time to provide feedback. We estimate that the few short questions found in the link below will take less than three minutes of your time. The survey will close on April 21, 2021.
Access the survey link here.
If you have any questions regarding the survey or webinars, contact Alex Anderson, DNR Forest Products Specialist, at 715-492-0571 or Sabina Dhungana, DNR Forest Products Specialist, at 608-220-4531.
The United States Department of Agriculture (USDA) announced new programs to bring financial assistance to producers, including assistance for timber harvesting and hauling firms, who were impacted by market disruptions caused by the COVID-19 pandemic. The USDA will re-open the Coronavirus Food Assistance Program (CFAP) signup for at least 60 days, beginning on April 5, 2021. Please visit the USDA Pandemic Assistance webpage for more information.

When people think of wood-based panel products, plywood and oriented-strand board (OSB) usually come to mind. However, a vast array of panel products whose primary building block is wood do not fall under the auspices of plywood or OSB. Before we explore those, it’s important to understand the distinction between “structural” panels and “non-structural” panels.
As the name implies, structural panels are designed to bolster the strength, stiffness and resistance of the items they adhere to. Plywood, generally, is utilized in commercial structures, whereas OSB is more common in residential construction.
Both plywood and OSB function as cladding for roofs, walls and subfloors. In Wisconsin, various plywood manufacturers generally produce hardwood plywood for decorative applications, such as furniture, cabinets, pinblocks for pianos and many others. There are also two OSB manufacturers in Wisconsin that utilize OSB as a base for their siding product.
Alternatively, non-structural panel products are primarily represented by medium-density fiberboard (MDF), particleboard and hardboard. Like OSB and plywood, these panels are prized for their dimensional stability and textural consistency.

Were you shocked by your mill or plant’s power bill recently? Then 2021 might be a good year to consider adding a wood-fired combined heat and power (CHP) system or upgrading your existing biomass-fueled boiler system to add power generation capability.
Operators and managers of mills or other forest industry plants looking to reduce energy costs may qualify for the 30% energy tax credit included in the 2021 Federal Omnibus spending bill. Organizations may also be eligible by upgrading an existing biomass-fueled boiler system to add power generation capability. Biomass energy systems with more than 150 kW of electricity generation capacity may be eligible for the tax credit. To qualify for the energy tax credit, construction must start before Jan. 1, 2022.

This winter, the Forest Products Services team hosted three webinars on different aspects of manufacturing lumber. Each webinar highlighted principles from the recently published Forest Products Technical Guides.
Recordings of these webinars are available. These recordings expand on each topic, filling in some details about the industry.
We look forward to offering future webinars to highlight Wisconsin’s forest resources. Thank you to our partners Lake States Lumber Association Education, Northcentral Technical College and UW-Madison, for their help in putting together these resources and webinars.

Tree City, Tree Campus and Tree Line USA program participants: please review the Arbor Day Foundation’s following expectations regarding the 2021 program recognition standards.
Tree City USA Standard 4 – Proclamation and Arbor Day Observance: We will require a signed Arbor Day proclamation on all 2021 applications. Arbor Day observances and celebrations will not be required, but cities will be highly encouraged to publicize their community’s recognition as a Tree City or celebration of Arbor Day.
Examples of things communities could do to observe while socially distancing: Facebook live tree planting, social media post encouraging citizens to celebrate Arbor Day, newspaper article, radio ad, etc.

The Wisconsin Department of Natural Resources (DNR) Urban Forestry Grant program awarded $104,920 to six Wisconsin communities for urban forestry projects during the second round of our 2021 funding. These funds were originally reserved for the Catastrophic Storm Grant program but were not needed through the winter months.
The communities receiving funds are the City of Cedarburg, the City of Delafield, the Village of Grafton, the City of Menasha, the Village of Shorewood and the City of Sun Prairie. Each grantee will receive an equal part of the available funding for $17,486.50. These urban forestry grants must be matched dollar for dollar.
The Department of Natural Resources Urban Forestry Grant program funds projects consistent with state and national goals to increase the urban forest canopy and its benefits. The urban forest encompasses trees on both public and private property.
