City Nature Challenge Results 2024
Congratulations to everyone who contributed to City Nature Challenge 2024. The results were announced yesterday, an amazing total of over 2 million observations were recorded globally. The most observed species was the same as last year, Mallard duck Anas platyrhynchos. La Paz in Bolivia remain impossible to beat, they recorded the most observations across every category with: 165,839 observations, 5352 species and 3593 participants!
Greater Belfast and the surrounding areas by numbers: we recorded 3177 observations, 841 species and had 63 participants across the four days. The average number of observations per observer was 50 and 67% of our observations were research grade. We were placed in the middle of the UK leader board 12th out of 24 cities. Our most observed species was the green shore crab, Carcinus maenas. It would be interesting to know if we are the only city with a crab as the most observed species. There were lots of interesting records, one particular highlight is a new plant species for Ireland, white rocket, Diplotaxis erucoides recorded by @grahamday in Belfast. You can look at the “STATS” page for Greater Belfast on iNaturalist for some nice graphics of our results.
Finally, thanks once again for participating and put the dates for City Nature Challenge next year in your calendar: 25 – 28 April 2025.
