RT Journal Article SR Electronic T1 Urban Tree Residues: Results of the First National Inventory JF Arboriculture & Urban Forestry (AUF) JO JOA FD International Society of Arboriculture SP 57 OP 62 DO 10.48044/jauf.1995.010 VO 21 IS 2 A1 Whittier, Jack A1 Rue, Denise A1 Haase, Scott YR 1995 UL http://auf.isa-arbor.com/content/21/2/57.abstract AB The volume and characteristics of urban tree residues associated with tree pruning and other urban forestry activities have never been well documented, yet disposal of this residue is subject to increasing regulatory actions. The regulatory actions have a considerable impact on the activities of commercial, utility, and municipal tree care operations. This paper reports the results of the first national inventory of the volume and characteristics of urban tree residues. Residues are classified as follows: chips, logs, mixed wood, tops and brush, leaves, lawn clippings, and stumps. Generators of residues include the following: commercial tree care firms, municipal park and recreation departments, municipal tree care divisions, county tree care divisions, electric/telephone utility power line maintenance departments, nurseries, orchards, and landscapers. The national inventory assesses volume, characteristics, and disposal of the residues on both a regional basis as well as by size of metropolitan area. Finally, irregular residue inputs associated with natural disasters are discussed.
