Fall webworm activity in July

Posted on by margueriterapp

Fall webworm started showing up in early July. This native insect feeds on deciduous trees and shrubs and appears every year in yards and forests. Fall webworm forms loose webbing over branch tips. It can even completely cover a small tree with webbing. Inside the webbing you will find both live and dead caterpillars, partially eaten leaves and frass (caterpillar poop).

Fall webworm is more of a cosmetic issue than a tree health problem, but if people are concerned, they can take some simple measures to remove them. Open up the webbing using a rake, fishing pole, long stick or another long tool.. This will allow predators to get at the caterpillars inside. Or people can use their tool to roll up the webbing, peel away from the branch and place the entire web in a container of soapy water for a couple of days.

Insecticides can also be used to control this insect. If you decide to go this route, make sure the insecticide is labeled for caterpillars/fall webworm and that it will penetrate inside the webbing. With all pesticides, the user needs to carefully read and follow label directions.

As a native insect, fall webworm defoliation is unlikely to cause any harm to healthy trees. Use a control method described above if you are concerned about the aesthetics of a defoliated tree. Do not prune off the branch or burn the nest. Burning will cause more harm to the tree than the caterpillars will.

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 2020 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.

Communities and organizations interested in applying for a 2020 Urban Forestry Grant may find the grant application informational video to be a valuable resource. It highlights priorities of the Urban Forestry program and discusses several other key aspects of the application process. The video is approximately eleven minutes long and includes topics such as the difference between startup grants and regular grants and how to contact an Urban Forestry Coordinator.

2019 First Downs for Trees

Posted on by margueriterapp

Green Bay Packers and DNR staff plant a ceremonial Sterling Linden tree in Titletown to help offset the Green Bay Packer’s carbon footprint produced by traveling to away games. Trees naturally sequester carbon dioxide, providing a long-term solution to the problem because trees sequester more and more carbon as they grow larger. This marks the 9th year of the Packer’s First Downs for Trees (FDFT) Program which has planted 5,144 trees to date throughout Brown County.

Invasive plant management on roadsides workshops

Posted on by margueriterapp

Invasive plants have been shown to impact Wisconsin’s economy, environment and human health. Roadsides are a key area where these unwanted plants establish and spread. These right of way habitats are challenging to work in but focused efforts can be successful in preventing spread and reduce invasive plant populations.

To help educate and jumpstart management, The University of Wisconsin-Madison Extension along with 4-Control are conducting roadside invasive plant workshops throughout the state. We invite you to attend one of these five regional workshops. While this training is available to anyone interested, the focus will be on training staff of municipalities that manage vegetation on roadsides.

Inaugural ‘Good Health Grows on Trees’ conference a success!

Posted on by margueriterapp

Whether it be a hike through the woods, time spent with your family at a local park or sitting beneath the shade of that stately red oak in your backyard, we, as urban forestry professionals and enthusiasts, experience and recognize the physical, mental and spiritual benefits of spending time outdoors in nature.

For decades, scientists have been researching and documenting the health benefits that trees and nature provide, and as urban populations continue to rise, the impact of nearby nature on human health has generated a lot of interest in our world of urban and community forestry.

To further that conversation in Wisconsin, the first ever ‘Good Health Grows on Trees: The Influence of Nearby Nature on Public Health’ conference was hosted by the DNR Urban Forestry program at the Rotary Botanical Gardens in Janesville on May 30th.  Continue reading “Inaugural ‘Good Health Grows on Trees’ conference a success!” →
