Late fall rains signal the start of mushroom season, which can last until spring in the Bay Area. Though only experts should forage and eat wild mushrooms (following park rules about harvesting), anyone can appreciate the rich diversity of these ephemeral fruits of the forest.
You may not think of salmon when visiting the redwoods in Muir Woods, but it's home to a population of Coho Salmon. Redwood forests provide ideal salmon habitat, providing woody debris to protect young salmon in the creeks and keeping them shaded and cool. But the Coho in Muir Woods' Redwood Creek are endangered, and local biologists and volunteers are working to protect the salmon and restore their habitat.
