Hello HansR.
Different location. Different woods. Different perspectives.
4-5 years ago in the past a big old healthy live cottonwood tree was dropped that was never completely cut up. Left ground laying that I have finished savaging last Fall. It was clogging up our west side yard:
Note I have just rough steel wedges block split it. Have it up off the ground. Rick/single row stacked to final dry and season. That black is a now a mold grown. This can only be taken inside the house once fine split an armload at a time to not trigger molds allergies reactions.
All of the smaller branches and leaders were burnt up last winter already. Stored, overstocked, in the back of the pickup bed. Under a large portable air circulating, six-legged cabana cover. Then taken onto the front porch a wheelbarrow at a time. Arm loaded then directly into the woodstove.
Now here is a clay soil root-bound, years dead was standing Fir tree. Then bugs and woodpecker holed attacked. Rot weakened the winds snapped it at six feet in the lower trunk and it came down mid-winter:
I had to section it to clear the dogs walking pathway.
See the white mushrooms growth on it already? It has already lost 30% weight from rot loss.
Burnable, yes. Storable, NO.
The roadside bandmill site my wife is harvesting sawn dust, rotten woods sections, and years maple/cottonwood/alder leaf accumulations for our new raised bed planters:
Some few Fir edging slab boards she pulled out I’ll be able to cut up, store and use.
Some more cottonwood remains dumped off butts and gnarly sections . . . .maybe can be firewooded up too once I move up the 34 ton hydraulic wood splitter.
But how to cover store to not grow non-edible mushrooms and spoors spewing molds, eh?
Off the ground. Hard covered. Open sided for ventilation. NO TARPS. Tarps makes for rots and decays.
Just like meats. Just like vegetables. Just like fruits.
You can only safely long term store usually the best, the healthiest, least blemished of what was live harvested.
This applies to wood-for-fuels too. Some exceptions. Fruit woods from died trees seem to hold up well.
Walnut died trees, not. We were all coughing by the time I used up the last of three cords of “free” walnut died tree wood that was not two years dried seasoned. Molds.
Consider most of what I’ve pictured in these “free” woods as road-killed meat. More apt to sicken you then nourish you.
