MIS501 – Tree Risk Assessment (Non-Member Price)
A Minimum Industry Standard for Tree Risk Assessment
 
This standard covers the core standards of tree risk assessment for arborists in Australia and New Zealand. It is not a tree risk assessment system. Rather, the document provides a framework within which different systems for tree risk assessment may be applied.
 
About the MIS Series
 
This book is one in a series of Minimum Industry Standards (MIS) 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.
