Winter is an ideal time for many types of ecological and arboricultural work—provided you understand the seasonal limitations. For developers and project managers aiming to submit or validate planning applications before spring, tree surveys are often a critical part of the process.
Unlike general habitat surveys, BS 5837 tree assessments can be carried out year-round. This makes winter a smart time to get ahead of the curve—and avoid survey-related delays during the spring rush.
What a BS 5837 Tree Survey Covers
A compliant BS 5837 tree survey includes:
- Species, age, condition, and dimensions of all trees on or near the site
- Tree categorisation (A to U) to indicate value and condition
- Root Protection Area (RPA) calculations to inform site layout
- Constraints mapping for construction phases, including access and storage
If trees are to be retained, removed, or protected, most Local Planning Authorities will require this survey as part of your application.
Why Winter is the Right Time
There are several benefits to commissioning a tree survey in winter:
- Reduced canopy cover makes structural assessment easier
- No nesting bird risks, provided any associated works are completed before March
- Better planning buffer—tree constraints identified early can inform layout and drainage design
Many clients mistakenly assume tree surveys must wait until spring leaf-out. In practice, acting now gives your team greater flexibility—and helps avoid planning bottlenecks.
