Care for your woods

Apply now for the 5th Wisconsin Community Tree Management Institute

Posted on by patricialindquist

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.

The Wisconsin DNR recently created a short video on Heterobasidion root disease (HRD) to compliment the updated guidelines that were released in 2019. The 5-minute educational video covers HRD biology, its significance as a tree disease, signs and symptoms, as well as preventative measures that landowners can take to reduce its introduction and spread. This is a great video for forestry professionals, landowners and the general public to learn more about HRD. Continue reading “Educational HRD video now available” →

Fighting invasives together through responsible firewood practices

Posted on by margueriterapp

By Marguerite Rapp, forest health communications specialist, marguerite.rapp@wisconsin.gov, Andrea Diss Torrance, invasive insects program coordinator, andrea.disstorrance@wisconsin.gov, and Tim Allen, DATCP forest pest program coordinator and nursery inspector, timothy.allen@wisconsin.gov, 715-891-8158

This time of year, many Wisconsinites warm up with firewood, whether that’s in a wood stove for the home or a bonfire with family and friends. While firewood is one of the most sustainable heat sources available, the forests that produce it are threatened when firewood infested by invasive species is moved long distances. Fortunately, we can reduce this threat together through responsible use, movement and sale of firewood and wood products.

Check your trees for EAB and plan for spring

The cold winter months are a great time to think about emerald ash borer and whether ash trees in your yard are suitable for treatment. The pest is currently the most damaging threat to trees in Wisconsin, killing more than 99 percent of the ash trees it infests.

Two side-by-side images depicting different stages of flecking on ash trees - on left side is light flecking in the upper canopy of a tree, on the right side is more severe flecking that extends down the trunk of the tree

Woodpecker flecking is an early sign of EAB infestation when it appears in the tops of trees (left). As the infestation progresses, flecking continues down the trunk and into lower parts of the crown (right).

From ashes to oaks

Posted on by patricialindquist

Dealing with the loss of ash trees to the emerald ash borer (EAB) can be disheartening, and the idea of replanting can seem overwhelming. But Tom Zagar, Muskego City Forester, saw a chance to try something new.

Tom manages a younger-growth woodland that had lost significant canopy due to EAB. After mowing down the invasive shrubs that blanketed parts of the woodland, “I recognized these areas as a prime opportunity to try to reestablish oak trees,” said Tom. “I especially wanted to plant white oak of local genotype.”

Early last spring, Tom and his team sprang into action. They collected loads of white oak acorns, most of which had pushed a root into the ground, with a gentle tug and a small shovel. They planted them in the cleared areas and protected them with tree tubes. Later on, when it was necessary to spray the invasive buckthorn shrubs that had re-sprouted, the tree tubes shielded the seedling oaks from herbicide.
