Firewood is any wood material that is collected and used as fuel.
Generally, firewood is not highly processed and is in the form of a type of recognizable log or branch compared to other forms of wood fuel such as pellets or sawdust.
Firewood can be seasoned (dry) or unseasoned (fresh / wet). It is generally classified as hardwood or softwood.
Firewood is a renewable resource. However, the demand for this fuel may exceed its ability to regenerate at the local or regional level.
Good forestry practices and improvements in firewood-using appliances can improve local wood resources.
Transporting firewood over long distances could potentially carry diseases and invasive species
