This Standard was prepared by the Standards Australia Committee CS/90 on Horticulture, to provide guidelines for the pruning of trees. The recommendations given in this Standard are intended to apply specifically to urban and amenity trees, but exclude pruning for fruit production and silviculture. In the preparation of this Standard, cognizance was taken of reference sources from the International Society of Arboriculture Certification Committee, Dr Alex Shigo, The Arboricultural Association of Australia, The Arboricultural Association of Western Australia, Ryde T.A.F.E. (Division of Horticulture), Burnley College and The National Arborists Associations of Australia and America. The objective of this Standard is to provide tree workers, government departments, property owners, and contractors with a guide defining uniform tree pruning procedures and practices in order to minimize the impact of pruning on trees.

Arbor Guy adheres to this standard wherever practicable to minimize the impact of pruning on trees and support tree health.
