A BS5837:2012 Tree Survey, is a technical document used to assess and record all trees on a proposed development site. The survey will identify all trees, and groups of trees with a stem diameter of over 75mm. The information gathered will include: Age, species, dimensions, tree structure, tree form, height, crown spread in 4 directions, condition, the presence of any biotic or abiotic impact etc. This information is collated, the trees are given a Retention Value and categorised for their importance- either as individual specimens or for their position in the surrounding landscape. The retention category will be used by planners to determine how the proposed construction will affect the trees on site. 

Heritage Tree Care Ltd. can also provide a Tree Clearance Survey. These surveys are the first port-of-call on sites that require tree removal to facilitate the proposed developments. A Tree Clearance Survey only records key tree identification and condition data, as the trees identified only require tagging and marking for removal. The preliminary survey is carried out in  reference to Architectural Plans for the proposed development. The Tree Clearance Survey is accompanied by a Tree Clearance Plan


These Tree Surveys are presented in the format of a spreadsheet, with the intended use of easy-to-understand reference documents. 

All of our reports are written and reviewed by appropriately qualified arborists in accordance with BS 5837:2012 Trees in Relation to Design, Demolition and Construction- Recommendations
