Fuels For Your Fire
Fire is a very important part of survival in the wilderness. It can be used for protection, the cooking of meals, and also for warmth. Certain fuels can be used to intense the purpose of your fire.
Fuels that can be used for warmth include bazel, apple, holly, and fire, which all burn quickly and brightly and give off a good amount of heat. For cooking, dense, hard woods like ash, beech, birch, oak, maple, sycamore, and hickory, all burn slowly and evenly. This gives off great heat and produces coals that can be used for slow cooking. It is also important to remember that the food may taste like the smell of the smoke which is affected by what you fuel you use in the fire.
If you are in a hurry to save the fire, emergency fuels that can be used are animal dung, moss, heather, dry lichen, and blocks of peat. Dried seaweed on the shore, animal fat, and sand that may contain some oil could also be used as emergency fuel.
There are also many woods to avoid using. This is because some resinous woods spit fire fiercely. These would include blackthorn, pine, chestnut, alder, willow, poplar, and even bamboo.
