Come and experience the last piece of lowland vernal pool grassland in the South Bay. The Don Edwards San Francisco Bay National Wildlife Refuge is inviting CNPS members to guided tours in the Warm Springs Unit, a site with limited public access. These tours are being offered at different times to capture the temporal and spatial diversity of this unique site, home to many listed, rare and unusual species.
At this time of year, the dry pools are dotted with saline tolerant, warm-season perennials such as alkali heliotrope (Heliotropium curassavicum), alkali mallow (Malvella leprosa) and alkali weed (Cressa truxillensis). Super bloomers like common spikeweed (Centromadia pungens) and alkali heath (Frankenia salina) display masses of flowers, providing important sources of nectar to pollinators. We’ll also seek out rare or unusual plants including Congdon's tarplant (Centromadia parryi ssp. congdonii), San Joaquin spearscale (Extriplex joaquinana) and Atriplex species.
