City Nature Challenge – past results
City Nature Challenge
What happened in 2022?
The City Nature Challenge in 2022 was once again a collaborative event with 445 cities from 47 countries taking part. In the UK, 14 urban areas took on the challenge. You can see the cities that took part on the City Nature Challenge UK Leaderboard.
Observations that are included are those made between Friday 29 April and Monday 2 May 2022. When collating the results the figures were taken as at 9 am, local time, on Monday 9 May in each respective country. The week following the event was to allow time for observations to be added to iNaturalist and the community to identify observations to the highest level possible at that time.
The official UK tally for the UK cities registered for the City Nature Challenge is as follows:
Total Observations: 55,871
Total Species Recorded: 3,434
Number of Observers: 1,849
Worldwide, the most commonly recorded species was Common Dandelion. In the UK this was the fourth most recorded. Garlic Mustard, Cow Parsley and Herb Robert topped our tally.
Blackbird, Robin and Wood Pigeon topped our bird list. Harlequin Ladybirds, Common Carder Bee, 7-Spot Ladybird and Speckled Woods were also commonly observed.
