BS5837:2012 sets out the requirements for a report on trees in relation to demolition, design and construction works. It includes a survey of trees both within and around the proposed development site, which could be affected by the proposal. The survey considers each tree, its’ condition and contribution to the setting, and the space it requires (Tree Constraints Plan). The report then considers and the relationship of the trees to the proposed development and how they will be affected (the Arboricultural Impact Assessment). It identifies which trees should be retained, and how this can happen within the development (the Arboricultural Method Statement). Mitigation can include planting new trees.
