Spot an animal on your way to work or University? See an insect on a plant near your home? Take a few photos and upload them to iNaturalist to contribute to observations of biodiversity all around you during the York City Nature Challenge from 25-28 April 2025.

During York CNC 2025, participating organisations will be holding events to connect you with nature. You can also make your own observations of animals, plants and fungi where you live, work or play during these days.
