Our two-day course provides advanced tree inspection training which will enable you to identify symptoms and defects from ground-based surveys.

The course is designed so you learn how to clearly and competently inspect potentially hazardous trees, recording your inspection process to form a part of a defensible system.

You will learn how to specify necessary remedial works, set against appropriate time scales, to manage tree related risk at accepted levels.

Who is this course for?

  • Anyone aspiring to carry out tree inspections at a professional standard
  • Existing professional tree inspectors who wish to consolidate their skills and update their knowledge

Ideally, you should be an experienced and qualified arborist, with at least a basic knowledge of plant and arboricultural science.

Also, some experience of carrying out tree surveys and inspections is preferred although not essential.

Course objectives

The course will provide you with training and information that will help you:

  • Understand your role in risk management, as a tree inspector

  • Adopt a systematic and professional level
  • Consistent method for carrying out visual tree inspections at a professional level
  • Collect relevant field data using a suitable format (a survey template will be provided during the course)
  • Interpret the body language of trees to recognise a range of symptoms that could relate to defects or structural weaknesses
  • Confirm the presence of defects and measure them against published failure criteria
  • Consider the impacts of potential remedial works on the range of benefits and values that a tree may have, for example amenity, wildlife, historical, veteran, rarity and public access
  •  
  • Write an appropriate remedial works specification
  • Prioritise remedial works by setting time scales reflecting the current level of risk
