Tree Inventory Surveys

Map, Record & Manage Tree Populations with Confidence

A Tree Inventory Survey is a comprehensive assessment that captures key data on trees within a defined site whether it’s a park, street, woodland, school grounds, or development area. Each individual tree is systematically logged and assessed for its species, dimensions, age, condition, and location, along with any notable ecological, visual, or cultural value.

This structured approach gives landowners, councils, and property managers a clear overview of their tree stock forming a vital foundation for informed tree management, planning, and compliance.

We can also include photographic records, tree tagging, and scaled mapping (CAD compatible) as part of your report, depending on site requirements.

  • Property png

    Efficient Budget Planning

    Use the survey findings to direct funds where they’re most needed — from routine pruning and risk mitigation to long-term replanting and biodiversity planning.

Supporting Development, Planning & Tree Protection

Tree Inventory Surveys are particularly useful when:

  • Highlighting key trees for retention, protection, or preservation orders
  • Informing planning applications, especially where tree loss or mitigation must be justified
  • Supporting rewilding or biodiversity net gain goals
  • Documenting changes in tree populations over time for estates or councils

They also help shape policy for sustainable land use, urban greening, and climate resilience particularly when used in conjunction with soil analysis or tree safety surveys.

A Tree Inventory Survey is far more than a list it’s a powerful tool for responsible tree stewardship. Whether you’re overseeing a small estate or an entire public space portfolio, it ensures your trees are documented, protected, and planned for strategically.

FAQ – Tree Inventory Surveys

What is a Tree Inventory Survey?
A Tree Inventory Survey is a comprehensive record of the trees on a site, providing detailed information about each individual tree or group. The survey typically includes species, dimensions, age class, condition, location, management recommendations and inspection priorities. Creating an accurate inventory allows landowners and organisations to understand the condition of their tree stock, plan future maintenance and demonstrate a proactive approach to tree management. Whether you manage a school, housing development, estate or commercial property, a tree inventory provides the foundation for informed decision-making.
Tree Inventory Surveys are beneficial for anyone responsible for managing multiple trees across a site. They are commonly commissioned by local authorities, schools, housing associations, estates, golf courses, businesses, developers and large private landowners. An inventory provides a structured approach to tree management, making it easier to prioritise maintenance, budget for future works and fulfil legal responsibilities relating to public safety. Even smaller sites can benefit from having an organised record of their tree assets.
Each tree is individually assessed and recorded using recognised arboricultural methods. Information may include the tree species, height, stem diameter, crown spread, age class, physiological and structural condition, estimated remaining life expectancy and any recommended management actions. Depending on your requirements, the survey can also record defects, pest or disease issues, Tree Preservation Orders, inspection frequencies and unique reference numbers. The level of detail is tailored to how the inventory will be used.
A well-maintained tree inventory helps organisations move from reactive tree management to planned, preventative maintenance. By understanding the condition of your tree stock, you can identify potential issues before they become significant, prioritise higher-risk trees and allocate maintenance budgets more effectively. Regular inventories also demonstrate responsible tree management, supporting compliance with your duty of care while helping preserve the environmental, landscape and financial value of your trees.
Yes. Tree inventories are designed to be living documents that evolve as trees grow and site conditions change. Regular inspections allow new defects, maintenance work, tree removals and replacement planting to be recorded, ensuring the inventory remains accurate and useful. Updating your inventory provides a clear management history and helps establish an ongoing programme of inspections and maintenance rather than repeatedly starting from scratch.
Absolutely. As part of the inventory, we identify trees that may require monitoring, maintenance or further investigation. Recommendations are prioritised according to the condition of each tree and the level of risk associated with its location and use. This allows property owners and site managers to schedule work in a logical and cost-effective way, ensuring resources are directed towards the trees that require the greatest attention first.
Yes. While no survey can eliminate risk entirely, maintaining an up-to-date tree inventory demonstrates that reasonable steps are being taken to inspect and manage your trees responsibly. This can be valuable when meeting obligations under the Occupiers’ Liability Acts and other health and safety responsibilities. Having documented inspection records and management recommendations also provides evidence of a proactive approach should the condition of a tree ever be questioned.
Yes. Where required, trees can be accurately plotted and referenced on digital site plans, allowing each tree to be easily identified for future inspections and maintenance. This is particularly valuable for larger estates, schools, public spaces and commercial sites where managing significant numbers of trees can otherwise become difficult. Mapping also improves communication between consultants, contractors and site managers when planned works are carried out.
The appropriate review period depends on the type of site, the number of trees and the level of public access. High-use locations such as schools, parks and public spaces generally benefit from more frequent inspections than low-use rural estates. Many organisations review their inventories every one to three years, with additional inspections following severe storms or significant changes to the site. We can recommend an inspection schedule that reflects the level of risk and your management objectives.
