Commercial Production of Log-grown Shiitake Class & Related Forestry Management

  • Saturday, April 29, 2023, 9:00 AM - 2:00 PM

Join Erik Schellenberg, Craig Vollmer and Mark Krawczyk on Saturday April 29th for a day of mushroom production and forestry. We will cover the basics and the details of shiitake production on logs with a focus on production efficiency at critical steps like inoculation, forcing, harvesting, and post-harvest handling. In addition, we will walk in the woods while discussing forestry management techniques and practices aimed at producing and harvesting the highest-quality bolts for mushroom production while enriching forest ecology.

Both Mark and Erik have many years of shiitake growing experience, and Mark has been producing them commercially while optimizing efficiency and regenerative capacity of the enterprise. Principles and insights of Mark’s recent publication “Coppice Agroforestry: Tending Trees for Product, Profit, and Woodland Ecology” will help to guide our discussion of woodland management for mushroom production. Craig Vollmer is the executive director of the New York Forest Owner’s Association (NYFOA), which is a peer-to-peer organization that helps land owners and stewards learn how to manage their woodlands.

If you would like to attend the class but require financial assistance, please contact the program leader, Erik Schellenberg, by email at or by phone at (845)-344-1234 Ext.260.
