Case reference FOI2025/00952
Received 3 November 2025
Published 30 November 2025
Request
I am undertaking an analysis of tree data and would be grateful if you could provide information as outlined below. I am happy to refine or narrow the request if necessary and appreciate any advice under Section 16 of the Act to enable the most efficient disclosure.
1. Tree Management System
Please confirm which tree management software package your organisation currently uses. If it is an in-house system, please state this; or state if none is used.
2. Tree Inventory Summary
Please provide:
• The approximate number of trees for which your organisation has management responsibility.
• The number of those trees that are subject to Tree Preservation Orders (TPOs).
3. Tree Data
Please provide available tree data for the period 2015 to the current date.
If the dataset is too large or would exceed the appropriate cost/time limits under Section 12 of the FOI Act, please provide a manageable subset of the data. I will calculate proportionality from this subset.
Would you either:
• Provide a link to a publicly accessible and downloadable portal, or
• Provide the data in CSV or XLSX format.
For each tree, I would be grateful if the following attributes could be included where available:
• Survey data capture date
• Tree number/reference
• Species
• Height
• Diameter at breast height (DBH)
• Crown dimensions
• Growth direction measurements (North, East, South, West)
• Tree location (Ordnance Survey coordinates, British National Grid reference, Global ID, or other locational parameter)
Where a tree has been surveyed on multiple occasions, please include all recorded entries (for example, Tree 1 may have data spanning 2015–2024, Tree 2 may only have data for 2023–2024).
4. Format and Clarification
If the data structure or field names differ from the list above, please include a brief explanation or a data dictionary so that the dataset can be interpreted accurately.
Response
1. Tree Management System Please confirm which tree management software package your organisation currently uses. If it is an in-house system, please state this; or state if none is used. SDDC use a software package supplied and maintained by Ra Information Systems: Ezytreev Asset Management System. 2. Tree Inventory Summary Please provide: • The approximate number of trees for which your organisation has management responsibility 8,348 inventory records of approximately 180,000 trees inclusive of woodlands. • The number of those trees that are subject to Tree Preservation Orders (TPOs). 2,025 3. Tree Data I’m afraid the rest of this request exceeds the appropriate cost/time limits under Section 12 of the FOI Act as we do not have this level management reporting within the computer system.
