RianMan will probably pop in to answer your question about the greenness of the trees and their type, but due to the lack of bark on the stumps, I would say that they are mostly seasoned. I will take a stab at the types of trees that do have bark from the first pic. Cedar on the left. Pine OR persimmon laying long and horizontal through the center of the pic and Cottonwood and/or oaks in the top right hand corner.

Fish on!,
