City Nature Challenge is an annual, global event using iNaturalist that encourages people in cities around the world to observe and document the biodiversity present in their urban environments. The CNC takes place every fourth weekend of April, starting from Friday through Monday. Cities compete with each other in a friendly competition to see which location can document the most species in their local area. The City Nature Challenge promotes citizen science, environmental education, and awareness of urban biodiversity, fostering a greater connection to the natural world. City Nature Challenge is among the several approved Citizen Science Projects.
iNaturalist and the City Nature Challenge directly support the goals of Master Naturalists.
- Cultivates a connection between individuals and their local nature in urban and metro areas.
- Fosters community building by organizing in-person walks, public outreach events, and online training sessions focusing on local flora and fauna.
- Utilizes the iNaturalist application to conduct field research and gather urban biodiversity data. Share this data with AAMN Partners, including Texas Nature Trackers, City of San Antonio Parks and Rec, San Antonio River Authorities, and other collaborators. The collected information will play a crucial role in informing policy and management decisions related to the urban environment.
- Encourages increased volunteer participation in biodiversity documentation within the Alamo Area Chapter and the wider public.
- Sparks enjoyment and engagement through friendly competition and collaboration!
