Help the San Francisco Bay Area show the world how biodiverse our region is by using the iNaturalist app to make as many observations of as many species as possible April 27-30, anywhere in the nine counties that touch San Francisco Bay! You can also help with IDs for other people's observations to increase our species count, come to a bioblitz, or even hold your own event!
Which city on Earth has the most nature and the most engaged residents? The City Nature Challenge 2018 (April 27-30) will help us find out! More than 60 cities on five continents are asking residents of and visitors to these urban areas to explore nature all around them and document the species they find - see the full list of cities at citynaturechallenge.org. Results will be announced Friday, May 4, so be sure to upload your observations by then!
