Vasey1, L.M. Schile3 1San Francisco State University, 2University of San Francisco, 3University of California, Berkeley 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 marsh 2. Petaluma salt marsh 3. Coon Island 4. Rush Ranch 5. Browns Island 6. Sand Mound Slough 3 4 2 5 1 6 CalFed Bay Delta Program This work is supported by CalFed Grant 1037

This was going to be carbon cycling, decomposition and productivity. This was going to be an introduction to diversity, but not overlapping too much with what Mike was going to produce. We discussed something about vegetation transition CalFed Bay Delta Program This work is supported by CalFed Grant 1037
