T1 & T2 – Field Maples (Front of Property) Reduce the crowns by approximately 3m in height and 1.5m radially to provide balanced crowns and reduce overhang above the public footpath. Remove all ivy from the stems. Remove the failed stem and leave the trees in a safe condition. T3 – Pine (Rear Garden) Crown thin the upper half of the canopy to reduce the dense reaction growth resulting from previous pruning works, matching the density of the lower crown. Undertake minor formative pruning to improve the overall shape. T4 – Cherry (Dead) (Rear Garden) Monolith the dead Cherry to approximately 3m above ground level, retaining the ivy on the remaining stem where practicable. The tree overhangs the neighbouring property. T5 – Holly (Rear Garden) Reduce the crown by approximately 2m all round, leaving a balanced and natural-looking crown. T6 – Cherry (Dead) (Rear Garden) Prune back the ivy covering the dead stem to reduce weight and minimise the risk of stem failure.

What these statistics cover

These figures describe applications collected by PlanningTrack for Welwyn Hatfield Borough Council, across all dates currently available. They are a partial dataset, rather than an authority-wide performance measure. The date range does not establish continuous historical coverage.

The approval percentage is approved records divided by approved plus refused records. Pending, withdrawn and unknown outcomes are excluded. No percentage is shown until there is an approved or refused record.
