Old tree responses to forest thinning

Status: 
Complete
Dates: 
January, 2016 to December, 2017

PROJECT OBJECTIVES:

1. Evaluate the 15-year-post-treatment growth response, damage and mortality of mature Jeffrey and ponderosa pine following individual tree (radial) thinning, stand level thinning and in adjacent untreated stands.

2. Use results to improve retention guidelines for individual mature Jeffrey and ponderosa pines and enhance silvicultural prescriptions used in ecological restoration projects.
