Time Is Right For Oak Tree Work

Do you know of a state, county, municipal or private crew that has been itching to do some work involving oak trees? Or are you a landowner itching to do some oak pruning or cutting?

Well, the time has arrived for smart and safe work on oaks.

It’s important for crews and managers to know that any damage done to oak trees from April 1 through at least mid-July — many say into September — could lead to a quick death for that tree. Frequently, one tree’s infection will also lead to eventual mortality for neighboring oaks.

Have you noticed black ash trees that have tightly curled leaves in scattered clumps, with lots of bare areas on the branches?

The problem might be cottony ash psyllid (Psyllopsis discrepans), a tiny, sap-sucking insect that has been in North America for almost 100 years but was first identified in Wisconsin in 2006. Its presence was reconfirmed in 2023, when it was found in several additional counties around the state. Since then, it has been identified in even more counties.

When it comes to fighting invasive plants, Wisconsin’s Cooperative Invasive Species Management Areas (CISMAs) are often the first line of defense (and offense).

These regional groups provide a localized resource for landowners looking for invasive plant education, identification support and assistance with controlling invasives on their properties.

With 13 CISMAs operating throughout Wisconsin, these groups accomplish a lot each year. CISMA efforts range from fieldwork outings and landowner education workshops to tool-share programs and day-long, control-based field trips.

DNR To Accept Seedling Orders For The Spring Starting Oct. 7

Posted on by wjaroch

The Wisconsin Department of Natural Resources (DNR) will accept seedling orders from Wisconsin landowners for planting trees and shrubs in spring 2025 starting Oct. 7, 2024. The high-quality seedlings are native species appropriate for planting throughout Wisconsin and grown at the F.G. Wilson State Nursery in beautiful Boscobel.

Seedlings grown by the state nurseries are used for reforestation and conservation plantings on private, public and tribal lands. These seedlings can provide future forest products and revenues, wildlife habitat, soil erosion control, living snow fences, carbon storage, aesthetics and shade for landowners and public land managers in every county. Any seedlings planted will also get Wisconsin closer to the goal of planting 100 million trees across the state by 2030; a part of the national Trillion Tree Pledge.

Every year, the summer ends faster than one could pronounce Liquidambar styraciflua, and this year was no exception. Hopefully, while you are trying to recall proper Latin pronunciations, your summer is still filled with enjoyable, productive or illuminating activities. That was certainly the case for the DNR Urban Forestry summer internship program. This summer, staff worked with Southern University students Taylor Colman and Priscilla Loh on a variety of different data collection projects, filling the internship’s eight weeks with species identification, tree mensuration and tree health assessments.

Group planOn Aug. 20, 2024, the First Downs for Trees program celebrated its 14th year with a ceremonial tree planting at Amelia Cornelius Park, Oneida Nation. The program is a cooperative effort between the DNR, the Green Bay Packers, Wisconsin Public Service and corporate sponsor Green Bay Packaging, Inc. The donated trees offset the Packers’ carbon footprint when flying to away games.

In 2024, 402 landscape-sized trees were planted by sixteen communities: Allouez, Ashwaubenon, Bellevue, Brown County, De Pere, Green Bay, Hobart, Howard, Lawrence, Ledgeview, Morrison, Oneida, Pulaski, Scott, Suamico and Wrightstown. The trees were provided by Meacham and Leaves Inspired nurseries. Since its inception, the First Downs for Trees program has donated 7,194 trees.

Have you noticed maple branches suddenly dying this summer?

Sudden mortality of maple branches during the summer in northern Wisconsin is often a result of squirrel damage that occurred in late winter and early spring.

In late winter and early spring, gray squirrels strip the bark of maples to get at the sweet maple sap. When the damage is extensive or severe, entire trees or branches will be killed immediately and will not leaf out in the spring.
