About Tree School
Tree School started in Clackamas County in 1991 as a mini-college program designed to attract a broad audience and offer a diverse array of educational topics to address the goals and challenges facing local forest landowners.
Classes are typically around 90-minutes long, meaning you can participate in around four over the course of the event.
Tree School also offers other opportunities for learning and networking, including field sessions/tours, demonstrations, vendor tables and exhibits, round table discussions, and Q&A sessions.
