Timber Stand Improvement (TSI)

What Is TSI?

​

Timber stand improvement (TSI) is a phrase used to identify forest management practices that improve the vigor, stocking, composition, productivity, and quality of forest stands. Improvement results from removing lower quality trees and allowing crop trees to fully use growing space. The chief aim of TSI is continued production of more and better timber products. These practices can be used to convert lower quality stands into faster growing and more productive forests of desirable species.
