Trees


	The most obvious source of biomass is trees. Woodfuel can be derived from conventional forestry practice such as thinning and trimming as part of sustainable management of woodland to ensure the production of high quality timber for construction, joinery and wood products, and optimization of biodiversity. It can also be derived from tree surgery operations and the management of parks, gardens and transport corridors.


	Virgin wood There are many different forms of biomass fuel obtainable from trees, but they are all categorized as virgin wood provided they have not been used for another purpose.
