Climate change is likely to cause substantial shifts in estuarine salinity and water levels over the next century, with higher summer salinities due to reduced snowmelt and higher water levels due to increased global sea-level rise. Our research is focused on evaluating effects of climate change on vegetation dynamics across the estuary, including potential impacts on plant community composition and diversity, primary productivity, and decomposition rates.

We are evaluating these dynamics at six marshes along a salinity gradient within the Bay-Delta, from China Camp to Sand Mound Slough. Field sites:1. China Camp SP salt marsh2. Petaluma salt marsh3. Coon Island4. Rush Ranch5. Browns Island6. Sand Mound Slough123456
