Golden oyster mushrooms (Pleurotus citrinopileatus) have eye-catching bright-yellow caps with branch-like white gills. Recently, more people have been noticing these gorgeous-looking clusters of mushrooms growing on trees in Wisconsin, especially in southern Wisconsin.

These mushrooms, prized for culinary delicacy, are native to eastern Asia. However, they are found in forests throughout the Midwest and northeastern United States, including Wisconsin.

Forest owners and land managers should look for beech leaf disease (BLD), a destructive beech tree disease in the United States, this summer.

Although it has not yet been found in Wisconsin, recent discoveries of the disease in Michigan and other nearby states highlight the continued importance of monitoring BLD’s expansion. There is potential for BLD to move into Wisconsin, as the eastern portion of the state overlaps with the native range of American beech.

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.”
