Assessment forms
Two levels, taken in order
A whole-site survey first to locate the problem trees, then a detailed assessment on the individual trees that carry risk. Going straight to Form 2 usually misses the trees that matter.
- Form 1 — Tree group inspection and risk assessment A comprehensive survey and basic inspection of every tree within the lot, with maintenance recommendations.
- Form 2 — Detailed individual tree risk assessment Detailed inspection of individual trees with defects or potential risk, with tailored measures to mitigate hazards such as collapse.
Tree works
Carrying out the work
Pruning is the most common form of tree care. Done properly it removes defective parts and improves structure, which benefits the tree and reduces the risk it poses to people and property nearby. All aerial work is carried out by a registered tree climber under a registered arborist's supervision.
- Tree pruning Thinning, deadwooding, structural pruning
- Felling and removal Including stump treatment and waste removal
- Tree stabilisation Propping, cabling and root-zone works
- Feeding and pest control Prescribed to the tree's condition
- Transplanting and planting Including root preparation before the move
- Tree tag design and installation For ongoing management and departmental correspondence
Documentation
Dealing with the departments
This is usually where property teams lose the most time. We prepare the documents and follow them through.
- Tree removal applications Prepared and submitted on your behalf for departmental records or follow-up — including collapse caused by construction works or storms, and branch failures that have caused injury.
- Complaints and enforcement letters When an enforcement letter arrives, a qualified arborist assesses the case in detail, advises, proposes mitigation or remedial measures, and prepares a record report for you.
- Compensatory planting proposals An ISA registered arborist prepares the letter of intent based on actual site conditions and your requirements, submits the proposal, and keeps responding to departmental requests afterwards.
