Tree Surveys

We will collect the standard data as specified in BS 5837 Trees in Relation to Construction (Recommendations) by means of a site visit and the use of our GPS enabled hand held computers, running FastMap Mobile and FastMap Office software, and LaserAce tree and distance measuring devices. For more information on these please click here 

Generally the following arboricultural information is recorded and stored for the preparation of other elements within BS 5837.

• Tree reference number (to be recorded on the Tree Survey Plan)

• Tree position (We operate to an accuracy of within one metre but can be more precise if required)

• Species, common and Latin name 

• Stem diameter, measured in millimetres at 1.5 metres above ground level

• Branch spread in metres on the North, South, East and West axis

• Tree height in metres

• Age class (young, middle aged, mature, over mature or veteran)

• Trees physiological condition (good, fair. poor or dead)

• Trees structural condition (e.g the presence of decay and cavities and any other physical defects)

• Preliminary management recommendations including further investigation of suspected defects that require more detailed assessment and the potential for wildlife

• Estimated remaining contribution in years (e.g less than 10. 10-20. 20-40 and 40+)

• Tree category grading as defined in table 1 of BS 5837 (Good, Moderate, Poor or Dead)

• Wildlife considerations and habitat potential

• Any other relevant matters

We will use a properly referenced Ordnance Survey topographical survey (usually prepared by others) as the base for our drawing and plotting activities. If needs be we can produce our own base drawing but if a topographical survey already exists then it is more cost effective to use that.

We will plot accurately onto the drawing the positions of the trees, their crown spreads and other relevant site features using software called ArborCad which is produced by Chris Skellern. We have relied on this software for many years. For more information click here.

The data collected relating to tree height, diameter and crown spread is processed and cross referenced to a spread sheet from where it can be exported into the body of the Tree Survey Report with no further requirement for retyping or editing. In this way accuracy is assured.
