A method for harvesting and an arrangement for processing wood. In a harvesting area, a baler (1) is used to bale small-dimensioned wood into bales belonging to different bale classes, wherein a compressed wood bundle (9) is bound by means of a binding member (10). Energy bales (11d) and raw material bales (11a to 11c) may be created in a forest. The raw material bales may be processed in a debarking device (21), wherein the wood contained by the bale is divided into a pulp fraction (26) and an energy fraction (25). The pulp fraction may be used in the manufacture of raw material, and the energy fraction may be used as fuel.
