The DNR Reforestation Program Needs Seeds

Posted on by janness

By Jeremiah Auer, DNR Regeneration Specialist; Jeremiah.Auer@wisconsin.gov

The DNR’s Reforestation Program needs red and white pine cones – more specifically, we need the seeds found within those cones for our reforestation needs. The Reforestation Program produces millions of pine seedlings every year at the Wilson State Nursery in Boscobel, and the only way we can produce those seedlings is with seed collected from the fields and forests of Wisconsin.

There are plenty of trees in Wisconsin forests that haven’t been around as long as the Wisconsin Woodland Owners Association (WWOA).

In many cases, the 46-year-old WWOA has facilitated the information sharing, networking and hard work necessary to keep as many of those trees as possible, along with the older ones, of course, green and growing.

WWOA’s mission statement is one of those simple ideas that needs a lot of effort to become reality: “(T)o conserve and enhance the private woodlands of the state through the following actions:

  • Sustainably manage our woodlands with informed management plans that utilize best silviculture practices.
  • Assist private landowners in achieving their management goals by connecting them with natural resource professionals and fellow woodland owners.
  • Educate the public on the value of woodlands for economic, environmental, recreational and wildlife habitat purposes.”

Fallen maple leaves have been observed under Wisconsin maple trees since late May.

The fallen leaves are typically of normal shape, size and color, but have a darkened petiole stub (i.e., leaf stem) remaining. A closer examination of the petiole may reveal a hollow feeding tunnel containing tiny larvae of the insect responsible for the damage inside: the maple petiole borer.

White grubs, the larvae of Wisconsin’s native May/June beetles (Phyllophaga spp.), can cause significant damage to forest plantings.

To help those who plan to plant seedlings and saplings, the Wisconsin Department of Natural Resources’ (DNR) Forest Health team has produced a fact sheet on white grubs, aimed specifically at forest plantings.

Please Submit Trees Planted This Spring!

Posted on by janness

By Dan Buckler, DNR Urban Forest Assessment Specialist; Daniel.Buckler@wisconsin.gov or 608-445-4578

When your newly planted trees are getting comfortable in their new homes, you’ve pulled the splinters from your hands and you find yourself at a desk asking yourself, “What now?”, we have an answer for you.

Please take a moment and record your trees in the Wisconsin Tree Planting Survey. Those submissions will then appear on the Tree Planting Map and be tallied toward the state’s pledge to the Trillion Trees Initiative. Governor Tony Evers signed the pledge to protect and restore Wisconsin’s rural and urban forests by planting 100 million trees in Wisconsin by 2030.

The manufacturer, Lallemand Plant Care, recently decided to remove Rotstop® C fungicide from the North American market.

As a result, the product is no longer available for purchase in North America. If you already have the product and have stored it in an appropriate space, you may still use it as a preventative treatment for Heterobasidion root disease (HRD) as long as the expiration date has not arrived.

“Acts of creation are ordinarily reserved for gods and poets. To plant a pine, one need only own a shovel.”

Those were the words of Wisconsin’s most prominent conservation expert, Aldo Leopold, who authored the famous book, “A Sand County Almanac” among his many achievements.

This month, everyone in Wisconsin will have the chance to follow Leopold’s advice – even if in a small way, because many small efforts can add up to a prominent positive impact on Wisconsin’s trees and forests.

Avoid Seedy Hitchhikers This Summer

Hitchhiking invasive plants, insects and pathogens are worthy of concern.

As you dream of days spent at the cabin up north, planting your garden or wandering in the woods, here are a few reminders to help you avoid bringing hitchhiking invasives along as you enjoy your spring and summer activities.

The Wisconsin Department of Natural Resources (DNR) encourages property owners to examine their trees for spongy moth egg masses and determine whether control measures are needed this spring.

Property owners who have oak, birch, crabapple, aspen, willow and linden (basswood) trees should be particularly watchful because the caterpillars of this invasive insect prefer these species. However, they will feed on many other kinds of trees and shrubs.
