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”

Eastern white pine (Pinus strobus) has historically held great ecological, cultural and economic value throughout Wisconsin, a tradition which continues today. For more than 100 years, however, it has been threatened by a non-native, invasive fungal pathogen called Cronartium ribicola, or white pine blister rust (WPBR).

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.
