Species Diversity In The Urban Forest: A Short Guide For Homeowners

Posted on by patricialindquist

“What kind of tree should I plant?” We are often asked that question as urban foresters. For me, the first thing that comes to mind is, “not a maple!”

Approximately 36% of trees in the Wisconsin Community Tree Map are maples.* Why is this a bad thing? All it takes is a pest like the emerald ash borer (EAB) or a disease like Dutch elm disease that targets maples, and suddenly, one-third of the urban canopy is destroyed.

By planting smaller quantities of many different species, we create a more resilient urban forest less affected by any single threat.

The Wisconsin Department of Natural Resources (DNR) recommends planting no more than 10% of a genus (for example, maples or oaks) and 5% of a species (such as sugar maples or bur oaks). Most Wisconsin communities are far from meeting those targets.

Protect Oak Trees From Oak Wilt By Pruning After July, Not Before

Posted on by eleanorvoigt

By Don Kissinger, DNR Urban Forester, 715-348-5746 or Don.Kissinger@wisconsin.gov; Paul Cigan, DNR Forest Health Specialist, 715-416-4920 or Paul.Cigan@wisconsin.gov

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.

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.

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

Posted on by patricialindquist

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.

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

Posted on by patricialindquist

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.
