Firewood

Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not heavily processed, and is in some sort of recognizable log or branch form, compared to other forms of wood fuel like pellets. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as either hardwood or softwood.

Firewood is a renewable resource. However, demand for this fuel can outpace its ability to regenerate on a local or regional level. Good forestry practices and improvements in devices that use firewood can improve local wood supplies.

Smoke from fire created by burning wood causes respiratory and other diseases. Moreover, transporting firewood long distances can potentially spread plant pests/diseases and invasive species.
