Tree Survey and Inspection Courses

Basic Tree Survey and Inspection (BTSI)

This one day course aims to provide specific tree survey and inspection training at a basic level for tree surveyors, contractors, highway engineers, tree wardens, grounds maintenance staff, rangers and other persons of a non-arboricultural background. The training will allow attendees to identify obvious defects from ground level and report their findings to a line manager.

  • Understand the legal and safety implications of hazardous trees
  • How to maintain your health and safety while carrying out tree surveys and inspections
  • To recognise hazardous trees
  • To determine the level of risk
  • To decide on an appropriate course of action
  • How to collect and the importance of maintaining adequate information
  • To understand your limitations

Who is the course for?

Any persons employed as local authority highway inspectors, forestry, woodland or arboricultural employees, estate or park rangers, farmers and other landowners or their employees who may have responsibility for trees in the course of their work. Additionally, this course may be useful for those who work with trees in a voluntary capacity.

Pre-requisites: None


Intermediate Tree Inspection (ITI)

This two-day course bridges the wide gap between BTSI and PTI.

The course will provide training and information to help you:

  • Understand the legal framework; statute and common law affecting tree inspections; the duties and liabilities of tree owners and managers; and your role within the tree risk management process and the skill and knowledge levels required by you to fulfil your role
  • Adopt a systematic and consistent method for carrying out visual tree inspections and write a specification for remedial works (recommended to control risk), taking into consideration the potential impact on associated benefits and values
  • Confirm the presence of defects and compare them against published failure criteria and interpret the body language of trees to recognise a range of potential defect symptoms
  • Prioritise remedial works by setting timescales reflecting the current level of risk
  • Collect, record and retain relevant detailed field data, to aid and defend your decision making

The course has theory-based presentations, and instructor-led practical sessions on tree inspection practice, risk assessment and tree risk management options.

Who is this course for?

Anyone aspiring to carry out tree inspections at a professional standard, those trained to a (BTSI) basic level aiming for the Professional Tree Inspection (PTI), and existing professional tree inspectors who wish to consolidate their skills and update their knowledge.

Pre-requisites: None

This two-day course is now run through the Arboricultural Association; please check their training pages for dates and information:


Professional Tree Inspection (PTI)

Who is the course for?

Prospective trainees should be experienced and qualified arboriculturists with an in-depth knowledge of plant and arboricultural science, including a thorough understanding of wood-decaying fungi, identification and interpretation of signs and symptoms of ill health and structural failure across a wide range of tree species and circumstances. They should be thoroughly experienced in carrying out tree inspection and survey.

The three-day course aims to provide a specific tree inspection programme at an advanced level for competent arboriculturists to enable them to reach a level of competence that can be recognised as having received adequate training.

Candidates are required to inspect trees and specify the necessary remedial works and record the inspection process. This would then form part of a defensible system. The course is not aimed at covering report writing; however, the presentation of findings will be examined and advice given.

Pre-requisites: A minimum of arboricultural qualification at level three or equivalent, plus five years experience in carrying out tree survey and inspection, is expected. As a pre-requisite of attending the course, it is fully expected that you will have a detailed knowledge of tree biology, the tree as an undamaged self-optimised structure, biological and mechanical weaknesses, pathology, legislation, remedial options and their likely implications and the British Standard 3998 Recommendations for Treework. Also, any other specific arboricultural knowledge such as may affect detection and measurement of tree defects and recommendation of control measures that reduce the risk posed to an acceptable level.

Assessment: The objectives of the course will be assessed, by written question paper, fungi identification and practical tree inspection. At the end of the course, candidates will undertake a competence-based assessment directly related to tree inspection.

The pass mark for the test is 70% overall and 70% in each of the two tree inspections.


Highway Tree Inspection

This one day course aims to provide specific highway tree inspection for highway network inspectors to allow them to identify obvious defects from ground level and then to report their findings to a line manager.

  • Identify obvious defects by visual inspection of the trees from ground level with the aid of binoculars, mallet and a probe: this may include an initial inspection by drive-by
  • Record defects and place the tree in a broad category of risk rating
  • Identify the required action upon finding a tree with an obvious defect

Who is the course for?

Any persons employed in the highway network. Additionally, this course may be useful for those who work with highway trees in a voluntary capacity.

Pre-requisites: The are no pre-requisites for this course
