This educational field day will focus on thinning your forest. Once you have established a stand of trees, thinning becomes your most important treatment for directing the course of forest development and stand conditions to meet your objectives. Through a combination of instruction and demonstration, this workshop will cover how trees compete and grow; decisions on the age, size and season of thinning; spacing and selection of trees to remove versus trees to retain; and methods for harvesting and yarding small trees in crowded stands.

Before the learning kicks off, an optional gathering will be held to remember Mark Havel, a leader in our forestry community who was instrumental in establishing the Thinning and Pruning Demonstration area at Hopkins Demonstration Forest in 1999.

• 9–10 a.m.: Morning welcome and refreshments, Mark Havel remembrance
• 10 a.m.–12 p.m.: Educational field day

Please bring appropriate outdoor clothing and footwear. Coffee, hot water and morning refreshments will be available.

This workshop will take place in the woods, where there will be periods of standing and walking on uneven terrain. A bus will be available to transport individuals into the woods from the Hopkins Demonstration Forest parking lot.
