This book is one in a series of Minimum Industry Standards produced by Arboriculture Australia Ltd and the New Zealand Arboricultural Association in consultation with the national arboriculture community in both countries. These industry peer-reviewed documents provide a ‘body of knowledge’ which is shared by practitioners and can be used as the basis for training, dissemination of skills and professional development.


This book covers the basics of tree climbing equipment and tree access using a variety of tree climbing skills and techniques. Many other techniques, climbing systems and climbing equipment configurations are possible which are not discussed in this document. Nevertheless, the skills and techniques presented in this document form a solid foundation on which practitioners can build.
