Native Creekside Plants for the East Bay

For creekside gardens that are beautiful, easy to care for, drought-tolerant, erosion-resistant, and welcoming to native butterflies, insects, and birds, try these East Bay natives.

FOR CREEK-FRIENDLY GARDENING

Minimize paving; landscape and grade so that water soaks into soil and doesn't run to storm drains, creeks, and the Bay.
Mulch deeply; use compost or other natural fertilizers that release nutrients slowly, so they stay in your yard and don't run off to creeks and the Bay.
Control pests with non-toxic alternatives; especially avoid products containing diazinon, chlorpyrifos, and pyrethroids, which poison aquatic life.
