Professional Tree Survey

This three-day course aims to provide specific tree inspection training at an advanced level
for competent arboriculturists, to enable them to identify defects from ground level, from a
climbed inspection or inspection aided by the use of a Mobile Elevated Working Platform.

• Recognize 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 prevent 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 e.g. amenity, wildlife, historical, veteran, rarity and public access.

Candidates will be assessed during the course either by written test, practical demonstration or oral questioning. Successful completion of the assessment will result in the Lantra Award of a Certificate of Training.
