Thinning Young Stands Field Workshop, Saturday, April 21, 2018, 9:00am-12:00pm, Schlechter Farm, Salem, OR.    If you are in the process of growing a young stand of established trees between 5 and 20 years of age, the question of thinning your forest–if, when, and how much–is likely on your mind. Early thinning to space young stands can be the best opportunity to keep your trees growing well and get the work done with relative ease compared to a later pre-commercial thin. But you might already be at the right spacing to go for 20 years. Attend this workshop to help you assess your situation and decide what’s right for you.

Registration is required but there is no fee. Detailed directions will be provided to registered participants. To register or get more information, call 503-655-8631 or email

Introduction to Clackamas Extension Forestry

We provide woodland owners, land managers, youth, and the general public with objective, research-based information and educational resources to help them make informed decisions. We bring state and national expertise to the community through our affiliation with the OSU Forestry and Natural Resources Extension Program and the OSU College of Forestry. We work collaboratively with many community organizations that have a shared interest in our region's forests, including soil and water conservation districts, watershed councils, landowner organizations, school districts and state agencies.
