Saturday, April 4, 1 pm-about 3 pm, Warm Springs vernal pools (San Francisco Bay National Wildlife Refuge)
Come see the wildflower rings around some of the last intact vernal pools in the East Bay! Visitors will enjoy learning about the unique features of vernal pool vegetation and surrounding grassland.
