Inspired by the City Nature Challenge—a global urban biodiversity “contest”, where cities compete against one another to monitor biodiversity within their cities—the Alberta BiodiverCITY Challenge invites Edmontonians to take part in a city-wide BioBlitz using NatureLynx, a new citizen science app brought to you by the Alberta Biodiversity Monitoring Institute. Between June 10–13, join our city’s naturalists, species experts, and environmental groups in documenting as many species as you can! Simply upload your photos of birds, plants, mammals, moss, lichen, mushrooms and insects to NatureLynx. Your contributions will be used to help understand more about the species that call our city home.
