Tree Care Guidelines

conferenceThe three following Guideline documents produced by NZ Arb have been available since December 2008 to both members and the wider public.  
The intention of this resource is to make information available for arborists, developers, planners, councils and the public when preparing reports, development plans, resource consent applications, policy or guidelines. *This is an all care no responsibility resource.



NZ Arb would like to thank all of those who had input into these draft documents, in particular, Gavin Donaldson, Rob Graham, Tim Errington and the members of the Auckland Regional Consents Arborist Forum.


Trees on Development Sites

 Damage to trees is often caused because of a failure to appreciate their vulnerability, particularly the root system which can decline in health following detrimental alterations to the soil environment from development. A tree protection plan including a Tree Works Methodology should be supplied with every development application.



Tree Protection Fencing

 All trees which are being retained on site should be isolated from the damaging effects of site development by protection fences and ground buffers. The barriers and ground protection should be installed before any materials or machinery are brought onto the site and before any demolition or development begins, including soil scraping or ground excavation.



Amenity Tree Pruning Guide

 The pruning guide sets out the requirements for the maintenance of amenity trees and gives an indication of currently accepted correct arboricultural pruning practices. The intention of this document is to encourage pruning practices and procedures that reduce the risk of hazard development, branch failure, pathogen infection or premature tree death. It is intended for use on amenity trees, including palms, and does not include practices which are specific to timber, foliage, fruit and flower production, root pruning, chemical pruning or sculptural forms such as topiary, espalier, and pleaching.

Encouraging, fostering, improving and educating in all aspects of arboriculture throughout New Zealand.
