Longitudinally Yours - A Decade of Grassroots BioBlitzes in the Bay Area

From the event page -

In 2017, the South Bay eagerly and persistently joined the fray with the formation of the BioBlitz Club, which hosts blitzes every month and sometimes two or three per month.

A BioBlitz is a kind of Flash Mob for Nature observation. People with any interest in nature - whether general or specific to one taxa like birds, bugs, or slime molds - gather at a specific place on a pre-announced day.
