Care for your woods

Report surviving elm in the forest

You can help keep native elm trees in the forests of Wisconsin! The US Forest Service continues to work on a project to identify Dutch elm disease (DED)-tolerant American elms native to Wisconsin forests. The goal of the project is to identify and propagate survivor American elms, especially from the colder hardiness zones 3-4, and develop a series of clone banks. Selections would eventually be screened for tolerance to DED. Ultimately, the goal is to make DED-tolerant American elm available for reforestation in northern areas, particularly as a component on sites currently forested by black ash.

If you live in hardiness zones 3 and 4, please look for evidence of surviving elms and report them to the US Forest Service.

Arbor Day 2020: Celebrating trees in a time of social distancing

Many Wisconsin communities found creative and resourceful ways to celebrate Arbor Day this year. These celebrations included drive-through tree giveaways, videos, art contests, games and puzzles, self-guided tree walks, small in-person celebrations and tree planting following social distancing guidelines, and more! Here is a sampling of the Arbor Day events that took place in Wisconsin this spring:

Adams: The city of Adams held a celebration on April 16th. Mayor Roberta Pantaleo read the Arbor Day Proclamation, and City Forester Joel Fell and another public works employee planted two trees in Burt Morris Park and four trees along boulevards.

Cedarburg: Please follow this link to read how Cedarburg Green celebrated its Year of the Tree despite Covid-19.

Cedarburg Green celebrates Year of the Tree despite Covid-19

By Jeanne Mueller, Cedarburg Green

“2020 is the year to focus on trees” read the headline in Cedarburg’s local newspaper. In January, a proclamation signed by Cedarburg’s mayor kicked off Cedarburg Green’s yearlong, multi-faceted promotion of trees. Cedarburg Green’s first success, a community talk on “Selecting the Right Trees for your Yard”, exceeded attendance expectations by over 225%. Interest in trees at this standing-room-only, inaugural event, held on February 24, seemed to be setting the stage for great things to come. Another hopeful sign was the mounting orders for trees being received as part of the organization’s annual bare-root tree sale.

Apply now for the 5th Wisconsin Community Tree Management Institute

Sponsored by the WI Department of Natural Resources in cooperation with partners

Wisconsin Community Tree Management Institute (CTMI) is a unique training experience designed for municipal staff with tree management responsibilities but without a strong background in urban forestry. The program is ideal for staff who spend just part of their time dealing with trees. Conversely, those with a background in urban forestry but new to management, will also find it useful. CTMI consists of approximately 38 instruction hours and requires students to complete an out-of-classroom project.

If you’re interested in applying, don’t wait – the 2020/21 class is filling quickly! The application deadline is June 12, 2020. See “How to Apply for CTMI” near the end of this article for instructions.
