The document discusses what an expert looks for when surveying trees. It examines the client's brief, how to gather both quantitative and qualitative data efficiently, and factors to consider like species, environment, and logic of the survey and remediation process. The expert emphasizes assessing tree hazards, risks, targets, and other values like visual amenity and ecology. The goal is to balance all factors, explain complexities clearly to the client, and ensure surveyor safety.

- 4. How little do I need to do meet the brief? why spend longer on the job than you need to? quantitative data is straight forward species, location, size qualitative data is more subjective how is tree hazard to be assessed? how is visual amenity to be assessed? what about any ecological value? some data may require research fungal fruiting bodies, targets 息 Jonathan Hazell What I look for when surveying Page 4
- 5. Where to start? Root Crown Stem 息 Jonathan Hazell What I look for when surveying Page 5
- 6. Whats the brief again? if an attribute is important, then assess and record it, for example unique reference number location species age health condition safe useful life preliminary management recommendations targets 息 Jonathan Hazell What I look for when surveying Page 6
- 7. What to consider? species characteristic appearance typical life expectancy susceptibility to certain conditions known associations with pests and diseases environment root disturbance adjacent properties, structures or utilities 息 Jonathan Hazell What I look for when surveying Page 7
- 8. What to consider? logic does the logic flow through, from initial survey to remediation? if not, change something! if there are no concerns whats the re-survey period? for some material if might be 20 years, for other it might be five if concerns are raised, are they dealt with appropriately? is the re-survey period suitable? does the proposed re-survey date take account of seasonal changes? is the remediation prescription sensible? 息 Jonathan Hazell What I look for when surveying Page 8
- 9. Post-processing important to ensure that entries in all data fields are consistent how will the data be managed sort by address, prescription minimise the number of treatments link with an existing Schedule of Rates? post-processing may change some of the timings recommended by the surveyor in general timings should be only be brought forward, not put back 息 Jonathan Hazell What I look for when surveying Page 9
- 10. Without a target a tree can not be a hazard hazard targetrisk 息 Jonathan Hazell What I look for when surveying Page 10 the area of most interest is where all three overlap
- 11. How to recognise hazard? how to recognise a tree hazard? Body Language of Trees Visual Tree Assessment how to assess the significance of a tree hazard? how to record the findings? 息 Jonathan Hazell What I look for when surveying Page 11
- 12. What is the risk? how to assess risk? how to record that assessment? 息 Jonathan Hazell What I look for when surveying Page 12
- 13. Is there a target? how to assess the target? how to record that information? 息 Jonathan Hazell What I look for when surveying Page 13
- 14. What about visual amenity? how to recognise the value of a tree as a public amenity? in certain situations this may be the preserve of a fellow professional, such as a landscape architect how to record those findings? 息 Jonathan Hazell What I look for when surveying Page 14
- 15. Ecological value? how to recognise a trees ecological value? this will often be the preserve of an ecologist how to record those findings? 息 Jonathan Hazell What I look for when surveying Page 15
- 16. Lets not forget surveyor welfare these two are fairy ubiquitous in urban areas! 息 Jonathan Hazell What I look for when surveying Page 16
- 17. Overall, whats most important? there are certain trump cards: health and safety nuisance these will generally be enough to override all other considerations 息 Jonathan Hazell What I look for when surveying Page 17
- 18. The judgment of Solomon how to balance all the competing and contrasting assessments that have been made? how to explain the complexities to the client? 息 Jonathan Hazell What I look for when surveying Page 18
