Our new oak wilt fact sheet and hickory dieback and mortality fact sheet are currently available on the DNR’s forest health oak wilt and bark beetle webpages and will be available in the DNR’s online publications catalog  in the near future.

Map of the known distribution of oak wilt in Wisconsin as of December 1, 2016.

Oak wilt, a deadly fungal disease affecting red oaks, was confirmed for the first time in Price County in 2016. In addition to the new county find, the disease was also confirmed in various townships in northern Wisconsin counties where we already knew oak wilt was present.

The map in the oak harvesting guidelines was updated based on the find.

Oak wilt is commonly found in the southern two-thirds of the state, but has been creeping northward. The disease was found for the first time in 2010 in Oneida County, in 2012 in Lincoln, Sawyer, and Vilas counties, in 2013 in Rusk County, and in 2014 in Washburn County. Oak wilt has been confirmed in all Wisconsin counties except Ashland, Bayfield, Calumet, Door, Douglas, Forest, Iron, Kewaunee, Manitowoc, Sheboygan, and Taylor.

The combination of trees coated in heavy ice and strong winds caused broken branches and bent or broken main stems. Working with storm damaged trees can be very dangerous, so landowners should carefully consider safety concerns and get help from  professional arborists or foresters when appropriate.

Finding bird friendly trees

Posted on by Ellen Clark

If you are looking for bird friendly trees and shrubs a database has been created that can help. The Audubon Native Plants Database allows you to enter a zip code and get a list of bird friendly native plants. You can filter based on plant type and what type of bird the plant attracts. The database also shows what kind of birds favor particular plants.

Trees are vitally important to cities, villages and towns. Like electricity and water, an urban tree canopy is part of a community’s infrastructure, providing valuable environmental, economic and social benefits. Well-managed urban forests pay back  nearly three times the cost to plant and maintain them. Continue reading “Spread the love: how to help your urban forests” →

Harvesting trees offers many benefits

Posted on by Kirsten Held

Keeping an ecosystem healthy includes management for wildlife habitat, aesthetics, soil and water quality, native biological diversity, recreational opportunities and forest products. One important component of sustainable forestry is the periodic harvesting of trees. In addition to providing forest products, supporting the local economy, and enhancing wildlife habitat, a benefit of timber harvests can also provide protection from wildfire. The spread of wildfire can be minimized by the removal of lower limbs of conifers and small trees near larger conifers reducing chances of a fire climbing into the crowns or tops of existing trees. In addition, the creation of logging roads or “fuel breaks” can slow or stop a fire and allow fire suppression crews easy access for suppression crews easy access for suppression and mop-up.  Learn about many other benefits of harvesting trees here.
