Vernal Pool Tours at Warm Springs Unit on Don Edwards San Francisco Bay National Wildlife Refuge

Are you interested in seeing the flower blooms around some of the last intact vernal pools in the East Bay? You will learn about the unique features of vernal pool grasslands, and hopefully observe the pools in what will likely be a good rain year! Participants will see endangered Contra Costa goldfields (Lasthenia conjugens), Downingia pulchella, several Plagiobothrys, and other native vernal pool and upland species.

Tours will occur at the Warm Springs Unit of the Don Edwards San Francisco Bay National Wildlife Refuge in south Fremont. These walking tours are typically in April and will be conducted on a Saturday and a weekday with two tours each. The tour will last 1.5-2 hours. Total walking distance will not exceed one mile, but terrain is uneven. Participants also must climb up and down a short step ladder to cross over fencing. Please wear sturdy shoes and dress according to the weather. Heavy rain will cancel.

Rather than trying to predict peak bloom times in the winter, we will be creating a notification list of interested people at this time. Please email us to get on the list! We will contact the notification list in March to provide the final tour dates. Typically these tours are in April and will be conducted on both weekend and weekday dates. Once dates and times are released, you will need to sign up to reserve a spot (sign up information will be sent with the final dates). Tours are limited to approximately 20 people each due to the sensitivity of the vernal pool ecosystem.

Place: Directions will be sent once confirmed.

RSVP: Please email Ivette Loredo at to be put on the notification list for tour dates.
