The City Nature Challenge is an annual competition among hundreds of international cities to increase awareness of urban biodiversity. Last year’s challenge totaled 1,694,877 observations, 50,176+ species, and 67,220 participants across 450+ cities worldwide. Check if your city is participating in this year’s challenge! If not, join the global project this year and sign-up your city to participate in 2024’s challenge!
This year’s challenge is active starting tomorrow, April 28, to May 1, 2023. All iNaturalist observations posted within a participating city will automatically count for the challenge.
If you see any surprising urban species, be sure to Tweet at us, and you could be featured as a future observation of the week!
Have fun discovering and recording your city’s wonderful biodiversity!
