    Robinia Tree to remove - The tree is unsuitable for its location within a domestic garden due to its inherent species characteristics. The tree produces prominent, sharp thorns along its stems and branches, presenting a risk to garden users, particularly at low level. In addition, it exhibits vigorous suckering, with numerous thorned shoots arising from the root system and spreading across the lawn, resulting in ongoing maintenance issues and reduced usability of the garden space. Removal and replacement with a more appropriate, less hazardous species is considered a reasonable and proportionate long-term management approach within the conservation area
