It's not so bad if you have reliable weather and it's not bitter cold.
Trying to log at -40 is very hard on the equipment...like any other gear outside. At cold but not bitter cold it can sometimes actually speed up logging as things like branches snap off easier with processors and logs slide easier with skidders....
But when you're trying to take a full years harvest off in a few months you have major challenges with:
- labour force. You're now a seasonal employer with challenges to find enough folks at key times
- weather. One warm spell can cause chaos. Especially if the roads don't freeze in
- occurred costs (paying loggers for wood delivered) vs. loss of wood quality due to age vs. time to produce product and make money. Was told years ago $1/m3 per month in cost for stored wood...no idea how true it is. If your mill consumes a million m3/year it adds up quick
- equipment costing is much higher due to short season = higher per hr rates needed to offset short working window.
Unfortunately muskeg - which is a form of wetland - often has poor growing sites and so not only are you dealing with the fun of access but you're also dealing with often poor form and poorer quality trees.
