Tree damage from white pine weevil is noticeable across Wisconsin this time of year. White pine weevils attack several different Wisconsin species, including eastern white pine, jack pine and spruce.
Adult weevils lay their eggs on terminal leaders in the spring. After the eggs hatch, larvae bore into the terminal and begin feeding downwards just under the bark which can result in the killing of a 1 to 2-feet section of the terminal leader as they feed. Terminal leaders will often have a wilted or “shepherds crook” appearance, and they will turn rusty red to brown late in the fall season. These dead terminal leaders will often break off during the winter.

Cities, villages, towns, counties, tribes and 501(c)(3) nonprofit organizations in or conducting their project in Wisconsin are encouraged to apply for a regular or startup 2022 Department of Natural Resources Urban Forestry Grant! The grants range from $1,000 to $25,000, and grant recipients must match each grant dollar for dollar. A startup grant of up to $5,000 is available for communities that want to start or restart a community forestry program. Grants are awarded to projects that align with state and national goals for increasing the urban forest canopy and the benefits it provides.
The Wisconsin Arborist Association (WAA) will host this year’s Fall Seminar in-person and virtually.
Created and administered by the Morton Arboretum in Chicago, the ArbNet Arboretum Accreditation Program is the only international accreditation program specific to arboreta. It fosters professionalism and collaboration and recognizes arboreta at various levels of development.
Sponsored by the Arbor Day Foundation, the Partners in Community Forestry conference will be held in-person in Louisville, Kentucky on Nov. 17 and 18. This conference is the largest international gathering of urban forestry practitioners, advocates, researchers and government leaders. Bring your skills, your hunger for knowledge and your passion for community forestry as you mingle with like-minded professionals; the thinkers, doers, and thought leaders in community forestry. CEUs will be available.
