Native plant wildlife corridor walk in Russian Hill

Leader: Susan Karasoff

Steep hilly walk from Ina Coolbrith Park, at Mason Street at Vallejo, to Francisco Park, at Bay at Hyde. You'll learn how native plants in your garden or balcony can extend and enhance wildlife corridors.

We’ll see restored native plants that feed wildlife in former oak woodland, grassland and dune scrub areas on clay, chert and sandy soils in public spaces belonging to SFRPD, SFPW, SFUSD and SFPUC. These public spaces are being planted with native plants to create connected food and habitat corridors for wildlife by SFRPD, SFPUC, Russian Hill Neighbors (RHN), California Native Plant Society Yerba Buena (CNPS-YB), and Francisco Park Conservancy (FPC).

All ages are welcome. Please bring hat, windbreaker, water and snacks if you or your friends and family will need to eat. The weather can vary in the same day from sunny to quite cool, foggy and very windy.
2 public restrooms on this walk. Street parking can be challenging.
