Awaiting decision Richmond upon Thames PA26/2934 Works to Trees Under TPO

Works: Trees

Still open. Anyone can comment while the consultation period runs, and comments go to the council rather than to us.

Proposal

Horse Chestnut (Aesculus hippocastanum): Crown reduce by 2-3m Finished height 12-13m, finished spread 9-10m. The specimen is a mature Horse Chestnut currently exceeding its appropriate managed dimensions relative to its position within the garden and proximity to adjacent structures and boundaries. Crown reduction of 2-3m is proposed to reduce end-weight loading on primary limbs, lower the centre of gravity, and mitigate the risk of limb failure during high wind events, a recognised vulnerability in mature Horse Chestnut due to the species' susceptibility to bleeding canker (Phytophthora) and structural weakening from Guignardia leaf blotch, both of which can compromise wood integrity over time. Crown thinning of 20% is recommended to improve light penetration and air circulation through the canopy, reducing humidity within the crown that can otherwise encourage fungal pathogens and prolong leaf-wetness periods associated with foliar disease. This also reduces sail effect and wind resistance, further lowering the risk of storm damage. Removal of dead, rubbing, and crossing branches is standard arboricultural best practice, eliminating points of future decay ingress and reducing the likelihood of included bark and structural failure at crossing points. All works are proportionate, do not exceed recommended maximums for a single routine reduction cycle, and are in accordance with BS3998:2010 (Tree Work – Recommendations). The proposed works will not adversely affect the long-term health, form, or amenity value of the tree, and the specimen will be retained as a positive contributor to visual amenity following completion.
