Snapshot CalCoast is June 17-July 9! Help us document California's incredible biodiversity on your own or at a bioblitz event near you.
For two weeks every year, the California Academy of Sciences—with support from the California Ocean Protection Council, the California Department of Fish and Wildlife, and the MPA (Marine Protected Area) Collaborative Network, and many other partners—mobilizes communities from Del Norte to San Diego to make and share observations of plants, animals, and seaweeds along the California coast using the iNaturalist app. By creating a real-time, statewide snapshot of current species ranges, we're building a community of observers that provides valuable data for scientists at local, regional, and state levels, and answering targeted research questions in support of California Marine Protected Areas.
