Decay Detection and Dysfunction

Tree Surveys consultants have extensive experience assessing trees for decay and dysfunction using state of the art instruments such as Picus Tomography, Resistograph, Chlorophyll Fluorescence and the Air Spade.

Tree Surveys

There are several types of tree survey available depending on your requirements UES can provide the following survey types:

Tree Report

Tree reports are often required for:
• Mortgage lenders and purchasers prior to completion
• Trees that are implicated in third party damages or
personal injury
• Trees that are implicated in subsidence

Tree Hazard Assessment

Tree inspections collect a range of objective and subjective information about individual trees in a systematic approach, where defects are suspected they are confirmed by a thorough examination.

British Standard BS5837 - Trees in Relation to Construction.

For each tree the following data is recorded:
Reference number of the tree
Species by common and/or scientific name
Height in metres
Stem diameter in centimetres, measured 1.5m above ground level.
The north, south, east and west crown radii in metres.
Age class: young, semi-mature, mature, post mature, veteran
Physiological and structural condition of the tree (A: healthy and vigorous, B: satisfactory, C: declining, D: poor, E: dead).
Preliminary management recommendations.

An assessment of the safe useful life expectancy of the tree (SULE) where: L: long more than 40years, M: medium 20-40 years, S: short 10-20 years, VS very short less than 10 years

Categorised on the plan by colour coding and in the schedule by letter, trees for removal and trees for retention. This should be based on consideration of the above data, filtered by a formalised system such as the Cascade Chart for Tree Quality Assessment (Table 1 of BS5837:2005)
