Harvesting small trees and forest residues

This report summarises the progress achieved under the auspices of the Activity “Harvesting small trees and forest residues” during 1992 – 1994. The work performed included literature reviews to assess potentially recoverable material as a function of harvesting system, analysis of factors affecting chipping quality and productivity, a comparison of firewood processing technologies, small tree and residue harvesting method reviews, a description of some prototype combination machines for recovering roundwood and forest biomass and an update on multiple-tree handling harvester head development in the Nordic countries.
