Pruning of Amenity Trees

AS4373-2007 Pruning of Amenity Trees

AS4373-2007 Pruning of Amenity Trees was produced by Standards Australia.  It was developed for Arborists, Vegetation Management Contractors and LGO’s to bring uniformity to the Amenity Tree Care Industry, by using up to date knowledge, best practise and sound arboriculture techniques.

Trees often require pruning to:

  • maintain clearance from utility services;
  • buildings and other infrastructure
  • reducing potential hazards
  • improve a trees structure, health and aesthetics.

AS4373 – 2007 promotes 2 types of pruning classes, Crown Maintenance and Crown Modification.

Crown Maintenance is pruning according to the growth habit of a tree, it does not reduce the volume of the crown, and retains the structure and size of a tree. It includes the following arboriculture pruning techniques:

  • Deadwooding
  • Crown Thinning
  • Selective Pruning
  • Formative Pruning

Crown Modification is pruning that changes the structural appearance and growth habit of a tree. It includes the following arboriculture pruning techniques:

  • Reduction Pruning
  • Crown Lifting
  • Pollarding
  • Remedial Pruning
  • Line Clearance

It is important that a suitably qualified and competent Arborist provides you with accurate and up to date information on what is the best arboriculture techniques/practise to carry out any pruning on your tree/s.  Not all pruning techniques are suitable for all tree species.  Specific pruning requirements will vary between species and location.

Bush and Beach Tree Services have a team of experienced and knowledgeable Arborists who will provide you with information and best practise tree care maintenance for your Green Assets.

AS4970-2009 Protection of Trees on Development Sites

Trees are an organism that require specific environmental conditions to continue healthy, stable growth.  It is rarely possible to repair stressed and or injured trees, hence the importance of this standard.

Trees to be retained on a development site must be protected at every stage of the development process.

Existing trees (appropriate species) can significantly enhance a new development by providing immediate benefits such as:

  • Shade
  • Storm Water Reduction
  • Aesthetic/Amenity Value

Most trees will take decades to establish but can be injured or killed in a short time as their vulnerability is not commonly understood.

Trees and their root system can occupy a substantial part of a development site and can have a major influence on the planning and proposed use of a site.

Often it is what you cannot see where a lot of damage can occur.  A trees root system can cover a large area, therefore early identification and protection of significant trees on development sites is essential from the outset.  Hence the importance of a project arborist’s involvement from the initial planning phase through to the completion of the development is absolutely essential.

Bush and Beach Tree Services can provide you with qualified and experienced project arborists who will provide the following project management/professional support:

  • Initial Tree Assessment
  • Report Preparation
  • Consultation with Designers
  • Consultation with LGA Representatives
  • Specifying Tree Protection Measures
  • Monitoring and Certification
  • Erecting Tree Protection Areas and No Go Zones

Our Team of Arborists are experienced and competent in arboriculture with a minimum AQF level 5 and or equivalent.

We have provided Project Arborists on various development sites throughout Sunshine Coast, Noosa, Gympie and Moreton Bay LGA’s.

Our Arborist’s are available by appointment on site or are able to assist with any questions you may have.

Local Government Area Requirements for Tree and Vegetation Clearing

Your Local Government Area (LGA) will have specific requirement as to how they regulate vegetation removal (plants and trees) from private land (freehold).

It is an offence to damage or remove protected trees and plants without council approval or exemption, penalties may apply.

Links are provided below for specific LGA’s in this area.  Our Arborists are available to discuss any concerns you may have or provide any information where possible.
