  T1 - Oak x 1 - reduce by 2m on height and 3m on overall spread, this will leave the tree at around 21 m in height with an approximate crown spread of 5-6 m. T2 - Oak x 1 - reduce by 2m on height and 2m on overall spread (as T1 above) T3 - Oak x 1 - reduce by 1-1.5m on height to clear dieback, prune back the south and east sides by around 1.5 m to leave these sections at about 2.5 m in length and so create a reasonably symmetrical crown. Reasons: trees 1 & 2 are woodland/field species rather than garden trees and these are now becoming somewhat large for this suburban location, Mr Ellis also has some concerns because the property is located within an area that has a shrinkable superficial site geology. Tree 3 is suppressed by the former two trees and as a result has developed a very asymmetrical crown with appreciable deadwood at the higher levels.
