Unravelling the Mystery of Sycamores

California sycamores are iconic riparian trees native to California’s storm-event driven and often seasonally dry streams and rivers.

The historical extent of sycamore alluvial woodland has been reduced significantly as a result of land use change and alteration of streamflow and sediment regimes. As part of the EPA-funded “Preparing for the Storm” project, the San Francisco Estuary Institute, Zone 7 Water Agency, and HT Harvey are collaborating to expand a regional dataset to better understand how sycamore distribution, health and regeneration patterns relate to geomorphic and hydrologic processes. Field-based sycamore surveys at sites along Arroyo Mocho and Arroyo Valle in Livermore Valley were conducted and analyzed with geospatial and hydrologic information. This work, as well as insights from other sycamore research such as genetic studies, is being used to develop regional suitability analyses to advance process-based restoration and provide planting guidance.

Outcomes of this work address the larger goals of the “Preparing for the Storm” project to develop regional visioning and implement projects that address flood, water quality, sediment, and habitat concerns under increasing urbanization and a changing climate. Overall, improving sycamore alluvial woodlands could help increase the resilience of California stream ecosystems to a changing future.

Horizontal Levees – Current Understanding and Future Opportunities.

This presentation will share lessons learned on the water quality benefits of horizontal levees from the Oro Loma Demonstration Project. We will also share the status of efforts to implement this concept on the Hayward shoreline and around the Bay.
