This Standard was prepared by the Standards Australia Committee EV-018, Arboriculture, to supersede AS 4970:2009, Protection of trees on development sites.

The objective of this document is to provide guidance on the principles and processes for retaining, protecting, and integrating trees on development sites. It follows, in sequence, the stages of development from planning to implementation. 

The major changes in this edition are as follows:

a) Inclusion of clarifying terms and definitions.

b) Correcting technical errors.

c) Increasing the size of the minimum encroachment into a tree root zone.

The terms “normative” and “informative” are used in Standards to define the appendices to which they apply. A “normative” appendix is an integral part of a Standard, whereas an “informative” appendix is only for information and guidance.
