Pima County Master Naturalists is hosting the 2022 City Nature Challenge in Pima County, Arizona. Be a part of this community science project by participating in this worldwide effort to document the amazing biodiversity of our region.
Started in 2016 as a competition between San Francisco and Los Angeles, the City Nature Challenge (CNC) has grown into an international event, motivating people around the world to find and document wildlife in their cities. Run by the California Academy of Sciences and the Natural History Museum of Los Angeles County, the CNC is an annual four-day global bioblitz to work toward a common goal, and to engage in friendly competition to see which city can gather the most observations, find the most species, and engage the most people.
Goals of the City Nature Challenge
- Connect people in urban/metro areas to their local nature
- Connect people to each other: build community in person & online around local nature
- Collect urban biodiversity data available to use for science, management, and conservation
- Grow volunteer biodiversity documentation globally
- Have fun through some friendly competition!
