To Leave or Not to Leave: Exploring Leave Trees in Minnesota

Harvest site with leave trees and satellite image of clumped leave trees

Minnesota's Forest Management Guidelines suggest retaining minimum of 5% of a harvest area in clumps and/or 6-12 scattered leave trees per acre. But what does this look like? When should we aim for more? How do we decide between clumped and scattered? Once these trees are retained, how do we track them into the future?

Instructors for these two workshops included staff from the Aitkin County Land Department, the St. Louis County Land and Minerals Department, Eli Sagor (UMN-SFEC), and David Wilson (MN DNR Guideline Monitoring). We visited a range of sites with different leave tree species, configurations, and objectives. These were in-person field days involving visits and discussions at several recent timber harvest sites managed by the St. Louis County Land and Minerals Department and Aitkin County Land Department.
