Wausau’s New Partners In Urban Wood Utilization

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

By Kyoko Scanlon, DNR Forest Pathologist, Kyoko.Scanlon@wisconsin.govor 608-235-7532 and Elly Voigt, DNR Forest Health Communications Specialist and Lab Technician, Eleanor.Voigt@wisconsin.gov or 608-273-6276

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

By Bill McNee, DNR Forest Health Specialist, Oshkosh, bill.mcnee@wisconsin.gov or 920-360-0942

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.

Tips For Holding Tree Planting And Distribution Events During COVID-19

The Arbor Day Foundation has created a short guide for holding safer tree planting and distribution events during the COVID-19 pandemic.

The guide includes tips for planning the event, communicating with volunteers and suggesting processes for tree distribution and planting. The guide also features additional tips for dealing with water, snacks and tools and more.

As emphasized in the guide, be sure to comply with local guidelines from your community health authorities.

To download the guide, visit the webpage here.

You can also view a short video summarizing information from the guide here.

First-Ever Virtual WAA and WDNR Urban Forestry Conference A Success!

Thank you to the more than 450 people who joined us for the first-ever virtual Wisconsin Arborist Association (WAA) and Wisconsin Department of Natural Resources (DNR) Urban Forestry Annual Conference. The conference’s theme was “Sustaining Urban Forests to Ensure a Healthy Future,” held on February 21-23.

In collaboration with the WAA, DNR staff worked hard to transition the annual conference to a virtual format. The conference retained key elements it has become renowned for, including engaging presentations, a welcome by State Forester Heather Berklund, a well-attended exhibition “hall,” an enjoyable session of ArborMaster Trivia and the annual awards ceremony shared by the Wisconsin Urban Forestry Council and the WAA awards program.

The DNR exhibition booth featured a new video by Grant Manager Chase O’Brien and Finance Specialist Nicolle Spafford and live Q&A sessions with O’Brien, Spafford, and Forest Health Specialist Bill McNee.

Seedlings Still Available for Spring 2021 Planting

The Wisconsin Department of Natural Resources (DNR) still has native tree and shrub seedlings available for spring planting.

Conifers available include jack pine 1-0 and 2-0, red pine 3-0, white pine 2-0 and tamarack 2-0. The pines tend to grow fast and perform the best in well-drained soils. The tamarack can grow in wetter soils. All are great for providing thermal cover to wildlife in the winter or privacy along a property line.

Hardwoods include river and white birch, black cherry, hackberry, silver maple, bur and red oaks, sycamore and black walnut. Many of these hardwoods provide forage or mast for wildlife and grow quickly in fertile soils.

Black cherry will begin producing fruit as soon as five years and aspen and birch provide buds for grouse even faster. The oaks and walnut take a while to produce acorns and nuts, but they will supply wildlife with food for many years once they begin. The silver maple, hackberry and sycamore thrive in wetter soils, giving those in heavy clay or lowland sites an opportunity for arboreal cover.

Consider talking to a DNR forester to get more information on tree planting and forest management. A good planting plan can focus a landowner’s efforts and create a strategy to achieve all their property goals. Find a forester near you using the DNR’s Forestry Assistance Locator webpage

For up-to-date information on seedling availability, please contact the state nursery at 715-424-3700. To order seedlings, print off a seedling application form here.  To have the ordering form sent to your residence, please contact a DNR forester near you or nursery staff.

Seedlings sold by the Wisconsin DNR are only for planting in Wisconsin and for reforestation, wildlife habitat and windbreak and erosion control purposes.

For more information about tree planting in Wisconsin using seedlings from state nurseries, please review our Frequently Asked Questions.

Oak Wilt Vectors Emergence User Interface Now Available

By Kyoko Scanlon, Forest Pathologist, Kyoko.Scanlon@wisconsin.gov or 608-235-7532 and Elly Voigt, Forest Health Communications Specialist and Lab Technician, Eleanor.Voigt@wisconsin.gov

Oak wilt is a serious disease of oaks that spreads to new areas when insects carrying oak wilt fungal spores land on a fresh wound of a healthy oak tree. To prevent oak wilt infections, it is important to avoid pruning, wounding and harvesting of oaks when these insects are abundant.

Predicting when these insects emerge in spring can be difficult as their emergence is highly weather-dependent and spring weather varies significantly year to year. The good news is that a new online interface is now available to provide users with localized information about the emergence status of the two most important insects that transmit oak wilt in Wisconsin. Because the interface uses a degree-day model constructed from insect trapping data and actual weather data, it is useful to refine the beginning of the periods when pruning, wounding and harvesting of oaks should be avoided.
