Residues Generated Mainly


Forest Residue - an overview | ScienceDirect Topics

Forest residues are generated as part of whole-tree operations in which trees are cut mechanically (e.g., feller-buncher) or manually and then skidded or forwarded to a landing area where the trees are delimbed, topped, and bucked [130].This method results in the accumulation of slash at the forest landing or roadside where it can be chipped and loaded directly into trucks.
