The Wisconsin Department of Natural Resources (DNR) is funding several accounts for communities or organizations to edit data within the Wisconsin Community Tree Map, a compilation of tree inventories from around the state. The map shows where trees are located and includes information about each tree, such as diameter, health condition and street address.

New Oak Wilt Vectors Emergence User Interface Available Online

Posted on by patricialindquist

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.

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.
