This report is based on our 2025 National BioBlitz Data and is used to develop our new scoring approach for 2026, which includes the following changes:
The datasets used in this analysis combine:
Only observations associated with the 2025 BioBlitz project are included. Records are filtered and processed to ensure consistency with the proposed 2026 scoring system.
This map visualises the potential scoring opportunity across the UK coastline under the proposed 2026 BioBlitz rules.
Rather than showing where recording has already taken place, this view highlights where effort is most valuable.
How to interpret the map
Each 5km coastal grid cell is assigned a potential bonus score based on existing coverage at multiple spatial scales:
Each cell is coloured according to the highest available bonus, meaning:
The map highlights the maximum potential reward for recording in that location.
This map provides a strategic view of recording priorities:
This approach ensures that participants are incentivised not only to record biodiversity, but to do so in locations where their contribution is most valuable.
Scoring and league table – national
To evaluate the impact of the proposed scoring system, a national leaderboard has been generated using 2025 BioBlitz data.
Scores are calculated based on:
This provides a simulation of how participant rankings would change under the 2026 rules.
