Forest measurement is beneficial to students as they use tools, apply geometry and accounting, and begin to understand the importance of sustainable forestry and connections to healthy forests of Wisconsin. Participants will practice with a variety of tools used to measure trees and estimate density, make management decisions, and consider what products can come from a harvest. LEAF Field Lessons (grades 5-12) that incorporate measurement will be introduced. Depending on weather and proximity to trees, this workshop may go outside for part of the time.
