Thinning an overgrown forest with heavy fuel load. Thinning out these overcrowded trees and removing excessive fuels to make the forest more healthy and less prone to catastrophic wildfire. I am using a Stihl MS 462 chainsaw with a 24 inch bar and square filed chain. The video is at 20x speed. The tree species include Douglas fir, Ponderosa pine, incense cedar, white fir, and Pacific madrone.
