Proposal

Cedar of Lebanon (T2) Reduce length of exposed branch to east by 2.5m to reduce chance of failure onto power lines and stop domino effect of branch failure. (Figure 1) Reduce three lateral branches over building so they are not protruding from the canopy. Reduce in length by 2-3 m. (See figures 2, 3 &4 for branches to be pruned and figure 6 for approximate pruning line.) Prune the next layer of branches above these ( possibly while stood on the lower branches with pole loppers) to give 0.5- 1 m clearance of the 3 lower branches. This is so that the growth points on the lower branches are not shaded out. Cedar Of Lebanon (T3) Reduce 2-3 branches to the SE top of canopy on grounds of conserving the canopy of the tree. (See figure 9) Reasons: T2 had a tolerable risk rating although minor pruning works have still been recommended. The recent history of T2s branch loss, although not necessarily indicating the tree will continue to drop limbs, does mean that the wind dynamics through the crown of the tree could be altered slightly. Minor crown lifting to the west underneath the long lateral limbs over the house will also have altered wind dynamics as well as some of the recent local tree removals along the A370 to south. Although these combined traits are not indicating a high probability of failure, the high occupancy of the building below (bedroom for two people with an occupancy of likely 2 people for 10 hours over a 24 hour period) and the size of branches that could fail give the overall risk rating as tolerable rather than acceptable. Reducing these three lower lateral limbs by 2-3 m into the line of the rest of the canopy would bring risk into the broadly acceptable regions. It is recommended that the next row of branches above these be tipped back from the growth on the ends of the pruned lateral branches by reducing 0.5-1m in places this is just so that the pruned branches below are not shaded out and can continue to grow. These lateral branches are important
