The emerald ash borer is an invasive insect from Asia first detected in the United States in 2002. Following its discovery, EAB has caused the death and decline of tens of millions of ash trees.

Now that spring has sprung, Wisconsin Department of Natural Resources (DNR) staffers can expect questions from the public about their yard trees.

However, the mission of DNR Foresters and Forest Health staff is geared toward focusing on larger, forested areas, not yard trees. Those questions fall under the purview of the University of Wisconsin-Madison Extension Horticulture Program.

The garlic mustard aphid, a tiny, dark, gray-to-green insect sometimes called the “grenade” aphid after the pattern of raised blotches on its back, was found in 2021 at the Holden Arboretum in Ohio. It could become a viable form of biocontrol for the garlic mustard plant.

Where Are Wisconsin’s Forest Products Going? A Closer Look At International Trade

By Ram Dahal (ram.dahal@wisconsin.gov), DNR Forest Economist, Forest Product Services

Wisconsin’s forest industry creates $24 billion of products each year. Historically, more than $1 billion of that total has included products sold internationally. However, did you know that in most years, Wisconsin imports forest products of an even greater value from international sellers?

Wisconsin’s international trade balance deficit exceeded $300 million in 2009, immediately following the Great Recession, but the deficit declined until 2012. In fact, Wisconsin had a trade surplus in 2012 but quickly resumed importing more forestry commodities than it was exporting (Fig. 1).
