Tree Health and Risk Assessment

Safety is a primary consideration for tree management in urban areas.  Trees are considered hazardous when they have structural defects which make them prone to failure which could cause personal injury or property damage.

Michael is professionally trained in assessment of tree health, risk and hazards.  He uses the International Society of Arboriculture (ISA) best practice methods (TRAQ) and Visual Tree Assessments (VTA) to identify externals signs of decay, structural defects, physical damage and site conditions which impact tree health and vigour.

Tools are used to detect defects in the root crown, trunk, branches and branch unions which can increase the risk of harm to people and property.  Where necessary, we work with colleagues to provide specialist diagnostic tests such as Picus Sonic Tomograph tests for internal decay detection.

Michael can advise on management options to correct tree hazards and minimise the risk of harm from tree or branch failure.  These include tree pruning, cabling and bracing, tree removal, target management and tree health improvements.

Tree pruning specifications can be prepared including crown thinning and remedial (restorative), selective, reduction and formative pruning.  These are prepared according to the Australian Standard AS 4373-2007 Pruning of Amenity Trees.

 

Our tree health and risk assessment projects include:

  • Tree risk assessment & report for a significantly leaning Pink Bloodwood with a large wound, heartwood cracks, wood separation and termites, Illuka
    Roadside tree risk assessment of structural defects including severed structural root, basal open decay column, poor stem taper, bow in stem and low live crown ratio

    Roadside tree risk assessment of structural defects including severed structural root, basal open decay column, poor stem taper, bow in stem and low live crown ratio, Dorrigo
