26/01477/TCA Awaiting decision
Westminster Abbey Dean's Yard London SW1P 3PP
The first tree in question is a Cercis canadensis. Over the past three years, its overall health has declined significantly. During the summer of 2025, I discussed my concerns with Barbara Milne, Head of Arboricultural Services at Westminster City Council, who I understand acknowledged the issues relating to the tree?s health and its likely continued decline. In light of this, I would like to seek permission to fell the Cercis canadensis prior to further deterioration, with the intention of replanting a more suitable replacement specimen. Adjacent to the Cercis canadensis is a Sorbus aucuparia. Although this tree is not in as advanced a state of decline, it has shown progressive signs of weakening over recent years. There has been an increasing presence of deadwood and a noticeable reduction in foliage during the growing season. While its condition is not as urgent as that of the Cercis canadensis, I would like to enquire whether it may be appropriate to remove the Sorbus aucuparia concurrently, thereby allowing for coordinated replanting and ensuring the long-term health and suitability of the site.
