Firewood is any wood fit for use as fuel. Usually you mean wood that is not processed, that is not ready as pellets, but stays in form of recognizable log or branch. You can heat-treat and season it, or leave it fresh and wet.
Simply it is wood meant for burn in fire, outdoor pit or campfire
Firewood: What It Is and How to Use It Safely
Kiln-dried firewood stays in controlled surroundings to remove the moisture, so it lights more easily and burns effectively. It counts as better product, because dry, easy and less smoking during burning. Some packages of kiln-dried oak firewood come in small, easily stored boxes, and burn quickly for smokeless fires according to need.
The wood type seriously affects, whether for cook, warming or only for enjoy the flame. Hardwoods as oak and maple give the most heat. They form long-lasting coals, so well answer for cook.
Oak and pecan occasionally rank among the best. Typical mix of hardwood firewood carries oak, ash, cherry, locust, maple and mulberry, with bits long around sixteen inches.
Softwoods as pine commonly present in some regions. Here where pine is plenty and recline many falling trees in the neighbouring woods, you burn it commonly without probelms.
First and chiefly, never take wood or materials of construction site. Here painted, treated wood, factory board or pallet wood. All they cover with chemicals, that forms dangerous smoke and fumes.
Initial logs well operate as alternative, easy for those, that hardly succeeds to flare campfire by means of real wood.
Motorhome and trailer campers usually have little place for firewood, so you buy it at the campsite or closely. Firewood handles help to well prepare. Some stores bid firewood for special vehicle builds, especially in areas as California, where you ban to bring firewood to sites.
Firewood transported long distances can propagate invasives. Larvae can exit, infest neighbouring trees and start them destroy. That taints the fun for forthcoming campers and reduces the trees for each.
The risk of invasives are big in campsites. Some states ban to move firewood even inwardly. In Michigan you confine to bring it from one district to another because of rules against Emerald Ash Borer.
At border crossings officials can control firewood and require it before entry. The best rule is move firewood as little maybe. Buy it inside fifty miles of the burn-place.
Wild camping occasionally gives a lot of free firewood, but many state parks ban to gather deadwood.
