I have 3 systems, but first, my area:
My forest is just 50 meters from where I process my firefood, but because therese a small river (15m wide) between these, then I have go over the village dam and make a stupid 1 km round trip.
#1. (replaced by 2.)
2 friends with chainsaws thin the forest
I drive my ATV over to some of the felled trees, I attach 2-6 (depending on mass and amount of branches) of them with chains to the ATV's trailer hitch.
If theres a larger log, I make the ATV end of it pencil shape, so it could be dragged better.
I drag all these logs to my processing area, where I eventually cut them into smaller furnace-sized bits, split them with a hydraulic log splitter or use a friend, who thinks he can split logs faster with an axe
After that we stack them on
pallets and cover the tops with waterproof panels - they dry in the wind for a few months/years and then they are ready for my 25 kW central heating furnace.
#2.
2 friends with chainsaws thin the forest
I drive my ATV over with its kickass log-tower-trailer:

Processing looks the same as in #1.
#3. (newest edition)
2 friends with chainsaws thin the forest and cut the wood into furnace-sized bits
I drive my ATV over with a old trailer attached to it:

Then I drive the load over to the processing area, whilst depositing a few logs every time the trailer goes over a stump.
I split the wood with my new hydraylic log splitter an everything is dandy.
I personally like #3 for firewood, as it seems faster - I actually havent timed if it is faster than #2.
I use #2 for logs I want to keep for building material. Which raises a question: How long can I keep a log, before its pointless to saw it into timber?
I use birch (Betula pendula) and European Spruce (Picea abies) for logs. Birch and Grey Alder (Alnus incana) for firewood.
I consider the Grey Alder as trash, since it doesnt offer much
energy density as firewood and is too weak for building material. Its the only legume tree I know, so its a love-hate relationship
