A member of the birch family, the alder tree comes in many different species. It makes fantastic firewood and kindling. Providing a really pleasant aroma, kiln-dried alder logs are a good choice for solid fuel as they burn well. However, as the tree grows quickly, alder is often not as dense as more popular firewood, although it burns well, nonetheless.  Easy to split without mess, thanks to its thin grains, it's a great choice for kindling when used with firelighters.
