CONSULTANCY
You might be building or you have recognised a hazardous tree. Gone are the days where you as a home or business owner could simply remove trees as you saw fit.
​
Do you need an Arboricultural report to accompany a Development Application or assistance in providing an adequate argument to condemn a dangerous tree in the eyes of the governing council body? Accomplished Tree Management has the required expertise and qualifications to satisfy all council requirements.
​
Reports on development sites are compliant with Australian Standard AS4970-2009 (Protection of Trees on Development Sites) and we also conduct Safety and Impact Assessments using Quantified Tree Risk Assessment (QTRA) Method.
ARBORI-CULTURAL REPORTS
We provide professional arboricultural reports and advice on legal matters pertaining to amenity trees and trees affected by development. The following are a brief outline of circumstances that may require an arborist report.
-
Home owners - When you require further evidence to prune/remove tree/s on your property.
-
Investors - When you require a Tree Inspection Program that is recorded on a database.
-
Insurance - When you need a mortgage or insurance quotation that requires a tree report
-
Developers - When you require an Arboricultural Report or Tree Survey and subsequent Tree Protection measures to be employed at the request of the local council in support of a Development Application
HAZARD ASSESSMENTS
Hazard assessment can be broken down into two categories, non invasive (Stage 1) and invasive (Stage 2).
Understanding the signs predisposing trees and tree branches to failure by interpreting their "body language" or changes in their environment is most commonly done in the first stage of assessment.
The second stage of investigation involves harming the tree, albeit in a manner that is unlikely to cause any long term harm.There are two techniques that can be utilised, one involves using a Resistograph®, a specialised drill which creates a discreet hole, approximately 1.5 - 3mm in diameter; the Picus® Sonic Tomograph however uses the velocity of sound waves to calculate the area of decay within a tree. These sound waves are activated from sensors mounted into the cambium (external) layers and placed radially around the tree.
​
As a registered QTRA (Quantified Tree Risk Assessor) means we use the QTRA method as a tree safety management to limit the risk of harm from tree failure while maintaining the benefits conferred by trees. We consider first the usage of the land on which the trees stand, and in turn, this will inform the process of assessing the trees.
