πŸ“ Regional Analysis Overview

This report summarises the results of the 2025 National BioBlitz, with a focus on regional biodiversity patterns and contributions by area.

In particular, we present regional league tables based on rarity-weighted species scores. This allows us to explore not just which regions recorded the most observations, but which contributed the most ecologically valuable or unusual species.


First of all lets get an overview of which regions have provided data. To do this we need to know the iNaturalist codes for the regional β€˜places’ that we are interested in. We have these saved ready in a csv file:

region_details <- read.csv("../Data/region names with inat codes.csv")

head(region_details)
##              Database.name                     KML.name
## 1 Yorkshire and The Humber Yorkshire & the Humber Coast
## 2         Northern Ireland       Northern Ireland Coast
## 3                    Wales                  Welsh Coast
## 4               South East             South East Coast
## 5            East Midlands   East Midlands Coast merged
## 6               North West             North West Coast

πŸ† Regional League Tables

As part of the National BioBlitz 2025, we’re celebrating not only national contributions, but also recognising the fantastic efforts made across different parts of the UK.

Below you’ll find regional league tables for each area where data was submitted. These tables show:

  • Total Score – the combined rarity scores of all species-level records
  • Species Count – the number of distinct species observed
  • Top Species Score – the highest score earned from a single species observation

These tables offer a great way to see which participants have made the biggest impact within their region.


🎁 Rock Pool Project T-Shirt Prize

To make things more exciting, the top contributor in each region (based on total score) will receive a limited-edition Rock Pool Project t-shirt!
So if your name is at the top β€” congratulations, and thank you for your incredible contributions to marine citizen science.


Let’s dive into the results!
