Book excerpt: As sea level rise accelerates, our shores are increasingly vulnerable to erosion. This study is the first systematic analysis of the rates of marsh retreat (erosion) or expansion (progradation) over time for San Francisco Bay. Key findings include: 60% of the marshes in San Pablo Bay have been expanding over the past two decades (1-4 m/yr) 6% are retreating Some areas have been expanding for over 150 years Shore change is a potential indicator of resilience Tidal marshes are generally backed by steep levees and lack transition zone. There are few opportunities for landward migration; so marshes will tend to evolve through shoreline change or by vertical accretion. Some marshes appear to be retreating, due to their vertical scarped edges, but are in fact found to be expanding bayward. This new information can provide the foundation for understanding drivers of shore change, such as wave energy, watershed sediment supply"

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The response of ecosystems to climate change is difficult to evaluate and predict, and often are constrained by anthropogenic modifications to the natural environment. Here, I assess the impacts of sea-level rise and extreme storm events on a tidal salt marsh ecosystem located in San Francisco Bay estuary (California, USA) that contains local endemic and endangered wildlife species. The San Francisco Bay estuary has been heavily impacted from human development resulting in the loss of over 80% of its historic tidal salt marshes. In this dissertation, I hypothesize that there will be short-term impacts from extreme storm events and long-term impacts from sea-level rise on the San Pablo Bay endemic marsh wildlife. The first chapter of this dissertation is a discussion about the current state of understanding about climate change impacts on salt marsh habitats and wildlife, using San Pablo Bay National Wildlife Refuge (SPBNWR) as a case study. The second chapter documents two extreme storm events in 2010 and 2011, and discusses impacts on available marsh habitats. At peak storm surge, over 65% (2010) and 93% (2011) of the marsh habitat for wildlife was under water, presumably increasing predation and drowning risk. In the third chapter, I evaluate if SPBNWR is currently keeping pace with sea-level rise and what biogeomorphic processes may be important. Subsidence and accretion was found to vary spatially, with only 37% of the marsh keeping pace with current sea-level rise rates. Surprisingly, I found widespread subsidence (55%) in areas adjacent to constructed levees. Using Akaike Information Criterion (AICc), I found that the distance from the sediment source (San Pablo Bay edge) was the most important covariate to determine accretion. In the fourth chapter, I develop a spatially-explicit, sea-level rise response model for SPBNWR to assess habitat resiliency to 2100. The model projected a loss of most high marsh habitat by 2050, and a loss of most mid marsh habitat by 2040 to 2060. Low marsh habitat showed a temporary increase in area between 2030 and 2050, with the peak (658 ha) in 2040. A large eastern portion of the marsh or 75% of the area (1,004 ha) converted to predominantly mudflat by 2060 with a 47 cm increase in sea-level. However, an almost complete conversion to mudflat occurred with a 75 cm sea-level rise by 2080, with

Book excerpt: Tall green grass. Subtle melodies of songbirds. Sharp whines of muskrats. Rustles of water running through the grasses. And at low tide, a pungent reminder of the treasures hidden beneath the surface.All are vital signs of the great salt marshes' natural resources. Now championed as critical habitats for plants, animals, and people because of the environmental service and protection they provide, these ecological wonders were once considered unproductive wastelands, home solely to mosquitoes and toxic waste, and mistreated for centuries by the human population. Exploring the fascinating biodiversity of these boggy wetlands, Salt Marshes offers readers a wealth of essential information about a variety of plants, fish, and animals, the importance of these habitats, consequences of human neglect and thoughtless development, and insight into how these wetlands recover. Judith S. Weis and Carol A. Butler shed ample light on the human impact, including chapters on physical and biological alterations, pollution, and remediation and recovery programs. In addition to a national and global perspective, the authors place special emphasis on coastal wetlands in the Atlantic and Gulf regions, as well as the San Francisco Bay Area, calling attention to their historical and economic legacies. Written in clear, easy-to-read language, Salt Marshes proves that the battles for preservation and conservation must continue, because threats to salt marshes ebb and flow like the water that runs through them.

Available in PDF, EPUB and Kindle. Book excerpt: One of California's most remarkable wetlands, Suisun Marsh is the largest tidal marsh on the West Coast and a major feature of the San Francisco Estuary. This productive and unique habitat supports endemic species, is a nursery for native fishes, and is a vital link for migratory waterfowl. The 6,000-year-old marsh has been affected by human activity, and humans will continue to have significant impacts on the marsh as the sea level rises and cultural values shift in the century ahead. This study includes in-depth information about the ecological and human history of Suisun Marsh, its abiotic and biotic characteristics, agents of ecological change, and alternative futures facing this ecosystem.
