17th March 2011.
I have been instructed by Sam Courtney of Barratts to carry out a survey on trees at The Cold Store Site,
Cwmbran.
Scope of Report
This Tree Survey has been undertaken within the recommendations of British Standards 5837:2005 and
current good arboricultural practice.
The survey entailed a visual inspection from ground level of all trees.
Each tree has been numbered and, where instructed, for future identification on site, have been tagged
using small durable metal or plastic tags.
Due to variations of existing ground levels through the site, height dimensions are estimated and are
given in metres. Accurate heights, measured with the aid of optical instruments can be provided where
instructed.
Trunk/stem diameters are measured at 1.5 metres above ground level, or immediately above the root
flare for multi-stemmed trees.
Estimate branch spread is taken in metres from the centre of the trunk, at the four cardinal points of a
compass, to achieve an accurate representation of crown shape.
An assessment of a tree’s age classification is made in terms of it maturity within the site’s landscape.
An assessment of a tree’s physiological condition is to be made as good, fair, poor, dead.
Data on the structural condition of the tree should be entered, e.g., collapsing, leaning and the presence
of any decay or physical defect should be noted.
Preliminary management recommendations include further investigation of suspected defects that
require more detailed assessment and potential for wildlife habitat.
An assessment of a tree’s future life expectancy is made as <10, 10-20, 20-40 or >40 etc.

Recommendations for Tree Protection during Development
Due to the high risk to established trees we would recommend the installation of protective fencing
prior to commencement of any works on site in accordance with BS 5837:2005 “Trees in relation to
Construction”. Trees should be protected using scaffold frame supporting weld mesh panel fencing
sited on the edge of the Root Protection Area as defined in BS5837:2005. These fenced areas should
not be used for the storage of any plant machinery or materials and personnel should be excluded at all
times; these fences should remain in situ until after final landscaping has been carried out, removed by
hand with great care to prevent compaction or root damage to established trees. The services of a
suitably qualified arborist should be sought prior to the commencement of each stage.
