I have been instructed by Mr Michael Rees of LRM Planning to carry out a survey on trees at Millennium Way, Barry. Scope of Report This Tree Survey has been undertaken within the recommendations of British Standards 5837:2012 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, 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. Trunk/stem diameters are measured at 1.5 metres above ground level, or immediately above the root flare for multi-stemmed trees. Estimated 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 its maturity within the site’s landscape. An assessment of a tree’s physiological condition is made as good, fair, poor, dead. Data on the structural condition of the tree has been entered, e.g., collapsing, leaning and the presence of any decay or physical defect has been noted. Preliminary management recommendations include further investigation of suspected defects that require more detailed assessment or potential for wildlife habitat. An assessment of a tree’s future life expectancy is made as 40 etc.

(Betula

Trees should be protected using scaffold frame supporting weld mesh panel fencing sited on the edge of the Root Protection Area as defined in BS5837:2012. 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.
