For the 11th consecutive year in Wisconsin, spruce budworm has caused significant defoliation on spruce, balsam fir and tamarack in some areas of the state.

This year, areas with widespread severe defoliation include Oneida and Vilas counties, with Forest, Iron, and Langlade counties also showing significant defoliation.

White Pine Weevil Damage And Management Options

White pine weevil (Pissodes strobi) is a native insect that can kill the terminal leader of white pine, jack pine and spruce. Wisconsinites often refer to this insect as Tip Weevil.

The insects prefer to attack stout terminal leaders. When the terminal leader dies, lateral branches grow upward and compete to take over apical dominance. This can leave a noticeable crook for decades. If two or more lateral branches take over, forking can occur. New terminal leaders may be attacked in subsequent years, causing more crook or forking.

Spruce and jack pine tend to recover better from weevil damage than white pine because the lateral branch that takes over apical dominance often creates a less prominent crook.

“Who do you know wants to rent a goat?”

Milwaukee television viewers of a certain age might recognize that twist on the old commercial slogan of automobile dealer Ernie Von Schledorn: “Who do you know wants to buy a car?”

Although Ernie is no longer around, the idea of having foresters use goat grazing to control interfering vegetation remains in use.

It’s a discussion worth talking about — and listening to.

Goat grazing was the topic of a recent edition of SilviCast, a monthly podcast about silviculture produced as part of a collaborative effort between the Wisconsin Department of Natural Resources (DNR) and the Wisconsin Forestry Center, based at the University of Wisconsin-Stevens Point.

LAKE GENEVA, Wisconsin — Fifteen employees of the Wisconsin Department of Natural Resources gathered at Big Foot Beach State Park on May 16 to learn more about using injections of systemic pesticides to protect the health of high-value trees at state properties.

Ten Wisconsin State Parks employees and five members of the DNR’s Forest Health team met with representatives of Rainbow Ecoscience and Bartlett Tree Experts to witness a demonstration of best practices for tree injections.

Document Trees Planted This Year

As there is every glorious spring, there has been a flurry of tree planting in Wisconsin. Each little tree, from seed to sapling, is a hope and prayer that we make for the future. But as each reader knows, that future might be many years away.

While you nurture these arboreal miracles, why not take a couple minutes to document the trees in the Wisconsin Tree Planting Map? The map was designed to help track trees planted to advance the state’s pledge to the Trillion Trees Initiative.

USDA Biological Control Facility Seeks Ash Trees To Battle Emerald Ash Borer

Asks Landowners To Donate Infested Ash Trees

The U.S. Department of Agriculture (USDA) is asking Wisconsin landowners for their help. Emerald ash borer (EAB) is an invasive insect from Asia that was first introduced into the United States in 2002. Since its discovery, EAB has caused the death and decline of tens of millions of ash trees. USDA uses ash trees to combat the pest to help preserve and protect the tree species.

Wisconsin landowners have donated live, infested ash trees to USDA’s EAB biological control program. The wood is used to grow EAB’s natural enemies and release them in Wisconsin and 31 other infested States as well as D.C. where they are attacking and killing EAB. USDA needs more ash trees to continue this work and is hoping more Wisconsin residents will consider donating their ash trees this year.

Governor Tony Evers attended the village of Germantown’s Arbor Day celebration on Friday, April 28. Village Park and Recreation staff organized the event with help from Wendland Nursery and the Wisconsin DNR. In addition to village staff and leaders, there were approximately 35 elementary students in attendance, all part of the Kids Club (an after-school program at County Line School). DNR Urban Forestry Coordinator Olivia Witthun spoke with the students and presented the community with their 19th annual Tree City USA award. Olivia was assisted by DNR Forestry staff Mike Warnke and Kim Sebastian. The local nursery provided a planting demonstration and gave each student a plant or vegetable to go home with.

In early April, Douglas County became the 53rd Wisconsin county added to the state’s spongy moth quarantine list after a discovery that the invasive insect (formerly known as gypsy moth) had become established in the county.

The United States Department of Agriculture-Animal and Plant Health Inspection Service (USDA-APHIS) and the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) made the determination based on results of a monitoring program of adult moths and other life stages.
