The Wisconsin Department of Natural Resources (DNR) urban and forest health specialists recommend not pruning or cutting oaks from April through July to protect oak trees from the often fatal oak wilt disease.

The spring season often draws property owners outdoors to soak up rays of long-awaited sunlight, breathe in some fresh air and begin seasonal yard maintenance and cleanup projects. While spring is a time to dust off yard tools like rakes, shovels and weed clippers, when it comes to the health of oak trees, keeping those chainsaws and trimming tools a safe distance away will go a long way to ensure that your trees stay healthy for many more spring seasons to come.

Wausau’s New Partners In Urban Wood Utilization

Posted on by patricialindquist

By Andrew Sims, City Forester, Wausau/Marathon County Parks, Recreation, and Forestry Department

Urban Evolutions

Urban wood utilization has become a popular topic of conversation within the arboriculture community. Not only is it a ‘feel good’ opportunity for communities to dispose of urban forest products, but a much-needed source of revenue as well. 

Historically, Wausau contracted with a local logger to haul material to mills. This contract was primarily for the pulp market, as many sawmills won’t accept urban wood due to unknown foreign objects.  As a result, much of the oversized material did not have the best end-use. Some were sold on auction by the truckload, and the rest was left to decompose. Finding those key partnerships, and being able to capitalize on them, was the key for Wausau to become successful at utilizing urban wood. A short description of two of the City of Wausau’s new partnerships follows.

New Oak Wilt Vectors Emergence User Interface Available Online

Oak wilt is a serious disease that occurs when insects carrying oak wilt fungal spores land on a healthy oak tree’s fresh wound. To prevent oak wilt infections, it is important to avoid pruning, wounding and harvesting oaks when these insects are abundant, generally April through July.

Predicting exactly when these insects start to emerge in the spring can be difficult as their emergence is highly weather-dependent, and spring weather varies significantly from year to year.

Look For Gypsy Moth Egg Masses And Prepare For Hatch; Slow-The-Spread Treatments Announced

Gypsy moth egg masses on the underside of a maple branch.

Gypsy moth egg masses are expected to start hatching 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 that never hatches can result in 500 to 1,000 fewer leaf-eating caterpillars.

Egg masses are tan-colored lumps about the size of a nickel or quarter. They can be found on many outdoor surfaces, including tree trunks, undersides of branches, buildings, rocks, fences, retaining walls, firewood piles and other outdoor objects.
