Tree Inspection Training

Professional Tree Inspection Refresher


This refresher training programme is designed to utilise existing knowledge and information provided as part of the Professional Tree Inspection programme. The programme is not designed to describe management methods for identifying systems of prioritising the inspection of trees with potential defects or to give training related to risk-reduction management systems, for example risk zoning, such as may be adopted by tree owners. The need for this refresher programme has arisen out of a recent inquest where council highway inspectors had not completed any hazard-related training for seven years, and to address the need for a common sense approach to reinforcing previously acquired knowledge and skills.

Targeted at Professional arboriculturalists who have previously successfully completed the Professional Tree Inspection course. Frequency of refresher training will greatly depend upon the how often the learner is involved in undertaking inspections, but it would be recommend on a five yearly basis.


  • Recognise the role of the tree inspector in risk management.
  • Identify the legal framework in the context of statute and common law that affect tree inspection and the duties and liabilities of the owner, manager and inspector.
  • Summarise how a tree system functions, what constitutes a safe tree and know that energy is required to keep the tree in a healthy/safe state.
  • Adopt a systematic and consistent methodology for carrying out visual tree inspection at an advanced level with the aid of binoculars, mallet and probe.
  • Collect data out in the field in accordance with the inspection instructions (having determined the scope and limitations) using a suitable format. (For this course a written survey template with appropriate headings will be used).
  • Recognise a range of observable mechanical and biological defects as seen in trees and confirm by the use of textbooks where necessary.
  • Identify a range of commonly seen pests, diseases and disorders that affect tree safety, confirm their identity by the use of textbooks, where necessary, and state the arboricultural significance of finding them in the field.
  • State the appropriate control/remedial measures required to eliminate or reduce risks identified in the inspection process to an acceptable level.
  • Determine when an aerial inspection is required, also if pro-active management recommendations can be made which may eliminate future defects from forming.
  • Prioritise the necessary tree/management works with time scales based on a broad category of risk assessment.
  • Identify when it is appropriate to recommend the use of decay detecting or measuring equipment, based on a basic knowledge of the working principles of commonly available equipment.
  • Understand that a balance between the remedial measure opted for and the range of benefits/values that a tree may have requires special attention, for example amenity, wildlife, historical, veteran, rarity and public access.
