On this job, you have to be self sufficient. So, wedges, axe, fuel, radio, whistle need to be worn up the tree. You climbline also needs to be bundled/packed and carried up there. You cant trail it on the ground or it might get trapped by a falling branch.....because there is no ground support. There is usually another climber within a couple of hundred yards, in case of an emergency.
You have a map, with dots to ID the trees. You tie 1-3 ribbons on the top of each spar depending on the dbh.
How many you get depends on size and how far away. Your up on the mountain for 6 hours tops. So, you might manage 6 x hundred foot trees in the day if there relatively close to each other. When they start getting upto 150 and 5ft dbh then you're not going to get that many done.
First couple days we had 2 feet of snow and a lot of hiking up hill and over fallen trees and creeks etc. Packing a huge amount of gear, not to mention. The climbing part was easy in comparison.
Over a few days we gradually moved down the hill and the snow got much less. But the trees got bigger.
Edit: forestry regs only require 1 tie in also. So you can strip the entire tree on the way up with a single flipline. Saves an aweful lot of time.
