Did you know the Least Bell's Vireo, one of the endangered bird species documented at the River Park, depends on willow habitat to survive? 🌿🐦
These small songbirds build their nests low in dense riparian vegetation, especially among native willow species like arroyo willow, black willow, and red willow. They rely on thick understory plants for shelter, nesting, and foraging near rivers and streams.
That’s one reason our willow restoration work is so important. Every stake planted helps rebuild critical habitat not only for healthier waterways, but for sensitive wildlife species that call the river park home.
Native plants supporting Least Bell’s Vireo habitat include:
• Arroyo, red, black, and sandbar willows
• Mule fat
• California wild rose
• Western sycamore
Thank you to all of our volunteers helping restore this ecosystem one willow stake at a time. 💚
