Community Spotlight: Rhinelander — How One Small Community Is Making Urban Forestry A Priority
By Tom Jerow, Rhinelander City Forester
View of the same street before and after urban forestry efforts.
The City of Rhinelander, like many communities with populations under 10,000, has struggled to maintain a vibrant urban forestry program. Funding and staffing are its main challenges. The city also faces a variety of urban forestry issues, including pests and diseases, species diversity, community engagement, catastrophic ice storms and aging sewer and water infrastructure. The latter is one of the most significant challenges. Continue reading “Community Spotlight: Rhinelander — How One Small Community Is Making Urban Forestry A Priority”
Repurpose Your Holiday Tree!
By Dan Buckler, DNR Urban Forest Assessment Specialist

To say that working on a Christmas tree farm in high school led me into forestry would be a case of significant historical revisionism. Still, that experience swam in the same waters as reading Lord of the Rings, going on family vacations to the mountains, having a nearby municipal forest and other things that showed me that trees were the way.
Since then, I have increasingly appreciated holiday trees and other green things brought into households, not (just) in the harbinger-of-gifts way, but as reminders of life against a cold, seemingly bleak background. “Things will get better,” these green things announce. “Just wait!” Continue reading “Repurpose Your Holiday Tree!”

Winter damage can significantly impact the health of trees. Keeping trees healthy through the fall is important for reducing winter stress. Provide water as needed to trees until the leaves start falling (for deciduous trees) or until the ground starts freezing (for conifers).
Watch For Woodpecker Damage On Ash Trees

The Wisconsin Department of Natural Resources (DNR) encourages property owners to watch for woodpecker damage to their ash trees this winter.
Woodpecker damage, often called “flecking,” happens when birds peck away some of a tree’s bark to access the larvae underneath. Flecking is a common early sign that an ash tree might be infested with emerald ash borer (EAB), an invasive insect. EAB is the most damaging threat to Wisconsin trees, killing more than 99% of the untreated ash trees it infests.

Cold weather is just around the corner, so now is the time to develop or revisit winter storm response plans. Ice storms are a recurring challenge in the Midwest. Freezing rain can add substantial weight to limbs, causing even healthy trees to snap. Ultimately, events like this can offer opportunities to reassess communities’ approaches to tree management and build stronger, more resilient urban forests.
