Tree Survey

 

The tree survey for a development site categorizes trees and/or groups of trees for their quality and value within the existing context. It provides the following information:

 

a)     an individual reference number for each tree or group of trees

b)     species (common names only)

c)      estimated height in metres

d)     stem diameter

e)     estimated branch spread in metres

f)      age class as follows;

                        young - a tree in the first third of average life expectancy for species.

                        middle - a tree in the middle third of average life expectancy for species.        

                        mature - a tree in the last third of average life expectancy for species.

                        over mature - a mature tree, which by reason of its physical or structural                                           condition, has an estimated remaining contribution of less                                                        than 20 years

                        veteran - ‘a tree which, because of its great age, size or condition is

                                       of exceptional value culturally, in the landscape or for wildlife’                                         English Nature.

 

g)     physiological condition

h)     observations on structural condition, as appropriate

i)       management recommendations, as appropriate

j)   estimated remaining contribution in years, and

k)   R or A to C category grading
