City Nature Challenge 2020: San Francisco Bay Area

April 23, 2020 - April 27, 2020

Help us celebrate the 5th anniversary of the City Nature Challenge and the 50th anniversary of Earth Day! Besides Los Angeles, San Francisco is the only city to now have participated in the City Nature Challenge for five full years – each year we’re documenting the amazing and unique biodiversity of the Bay Area, creating an incredible dataset that can be used for science, conservation, and management. Even though this year’s City Nature Challenge will look much different from years past, we’re still joining 250 other cities around the world in documenting the species that exist in and around our homes, yards, and neighborhoods! This year the CNC is not a competition, and instead we’re embracing the collaborative side of the event, thousands of us around the globe connecting to and documenting nature any way we can currently.
