Temporal trends in tidal marsh restoration at Hester Marsh, Elkhorn Slough, California

Understanding restoration trajectories and their sensitivity to climate is critical for designing effective adaptation strategies for restoration projects. Tidal marsh restoration often involves initial bare earth conditions that may be stressful to colonizing plants, especially on high elevation marsh platforms built to be sea-level resilient. Under these circumstances, stressors such as soil salinity may increase over time, but can be mitigated by strong rainfall. At Hester Marsh, a large tidal marsh restoration site in Elkhorn Slough, California, we evaluated passive restoration success, tracking colonization by plants whose seeds arrived naturally on tides, and active restoration success, monitoring greenhouse-grown transplants. Our investigation revealed non-linear restoration trajectories with high climate sensitivity, at the scale of the entire landscape and of individual plants. We found strong effects of drought on marsh restoration success indicators. Restoration success decre..., , , # Temporal trends in tidal marsh restoration at Hester Marsh, Elkhorn Slough, California
