  1. The Acer pseudoplatanus/ Sycamore tree, we are aiming at 4-5 meter crown reduction/thinning out dead wood crossing or rubbing branches to form a healthy aesthetically pleasing crown just reduced in overall size. 2. Fraxinus excelsior pollards to be reduced by 4-5 meters in height or back to old pollard points, again to form the healthiest example being reduced from high pollarded growth. 3. Prunus spp very small shrub tree in alley way to be reduced by 0.5 - 1.5 meters maximum as wobbling due to windy position and poor rooting (possibly root girdling) . 4. Sambucus nigra also in alley way wobbling so reduction of height again 0.5 - 1 meter maximum to reduce wobble from sail effect of windy position in alley way.

  Five Day Notice to remove a Beech tree at 22 Highgate Close, London N6 4SD. This tree has a very sparse crown and leaves have recently started declining and browning. In the last month the tree has sprouted large masses of giant polypores around the root plate. There are also hollow areas around the base of the tree when testing with a sounding mallet. Due to the size and location of the tree, near to the houses, the presence of white rot in the root plate poses a significant risk to the trees stability and safety and is only something that will get progressively worse. See photos attached. Please advise whether we should be heavily reducing the tree or removing the tree. I am conscious a Beech of this size and maturity is not going to take particularly well to pollarding as it will not heal well and with it already being under significant stress I feel the chance of it regenerating is very low, but would appreciate your perspective once you see it.

  Dawn Redwood. Tree T1 on Sketch Plan. Arboriculturist Conclusion "Given the presence of cracks in the wall of adjacent buildings, and the close proximity of the tree to the buildings, it is recommended that T1 is removed to ground level." Engineer's Conclusion "the best course of action to avoid any further movement on the existing building would be to remove the existing tree and underpin the existing foundation"

  Pembury House Nursery, Lansdowne Road, Tottenham, London, N17 9XE

  Ginkgo (T1) - fell. Reason: this is a female tree, that drops fruit all over the nursery playground. The children try to eat them, it gets into their clothes, shoes, hands, and all over the class room, creating an extremely unpleasant environment for the children and staff. Replant with another deciduous tree with similar potential size canopy (eg. Norway maple) Sycamore (T2) - Reduce the height of the tree by 4m. Reduce lateral branches in line with this (up to 2.5m). Reason: There is some decay at the base of the tree on the east side, spanning 40% of the circumference of the tree. The bark is flaking from ground level up to 1.5m, and use of the sounding mallet indicates the dysfunctional wood extends at least to the same height. The tree has a full crown, but has had selective branch length reductions in the past. The crown overhangs the nursery playground and neighbouring parking area. Lime x2 (T10 & T11) - Crown raise to 4m, removing epicormic growth. Reason: to remove the branches that touch the shelter to prevent damage.
