The City Nature Challenge is an annual event in cities worldwide where citizens are asked to observe and record as many wildlife species as possible. In 2022, it took place from 29 April to 2 May.
A total of 67,220 people worldwide took part in the 7th edition of the City Nature Challenge this year, 15,000 more than in the previous edition! One million six hundred ninety-four thousand eight hundred seventy-seven biodiversity observations were made in the 445 regions covering 47 countries, including Luxembourg. More than 50,000 species were documented, including 2,244 rare/endangered/threatened species. The City Nature Challenge again contributed to the highest number of observations downloaded with the iNaturalist application in one week.
All contributions made to the NCC2022 via iNaturalist can be found on the iNaturalist project page: https://inaturalist.lu/projects/city-nature-challenge-2022
