You can help improve San Lorenzo River habitat at River Health Days!
Are you interested in improving San Lorenzo River habitat to help native species of bugs, birds, fish, and plants thrive? Then sign up today for a River Health Day! At these monthly events, you help remove invasive plants like Himalayan blackberry and ice plant and reintroduce native species such as mugwort, willows, and sticky monkey flower. By revegetating the river bank, volunteers like you slow the spread of invasive plants along the 2.5-mile-long Santa Cruz Riverwalk and cultivate plants that provide bank stability, food, shade, and shelter for birds, insects, and wildlife. At the end of each River Health Day, you can look back on the habitat you helped with the people you connected with, and know that you made a difference in your community. Sign up for a River Health Day below to get important information about a specific event, such as where to meet.
