TSI employs cultural practices treating individual trees. TSI improves forested land by increasing quality of high value trees and expediting their growth process. Accomplishing this task by decreasing canopy competition allows more sunlight to reach the forest floor and reduces competition for nutrient and water uptake. TSI is also a highly valuable practice promoting natural regeneration of high quality trees, a reduction of invasive and unwanted low quality woody vegetation, and lessening of poor genetics within the forest stand.
