"This historical reconstruction documents patterns of variation and extent of habitat types throughout the Delta for improved understanding of species support functions and controlling physical processes within the native landscape. Knowing how different parts of the vast historical Delta looked and functioned provides needed information for future restoration strategies. Given the extensive changes to the Delta, the goal of the project is not to create a literal template from which to recreate the historical Delta. Rather the objective is to understand how large-scale restoration can support an ecosystem in the future Delta that reflects functions to which native species are adapted. This involves recognizing physical gradients along which ecosystems can adapt as the Delta continues to change." -- project web site.

An ecosystem in freefall, a shrinking water supply for cities and agriculture, an antiquated network of failure-prone levees—this is the Sacramento-San Joaquin Delta, the major hub of California's water system. Written by a team of independent water experts, this analysis of the latest data evaluates proposed solutions to the Delta's myriad problems. Through in-depth economic and ecological analysis, the authors find that the current policy of channeling water exports through the Delta is not sustainable for any interest. Employing a peripheral canal-conveying water around the Delta instead of through it—as part of a larger habitat and water management plan appears to be the best strategy to maintain both a high-quality water supply and at the same time improve conditions for native fish and wildlife. This important assessment includes integrated analysis of long term ecosystem and water management options and demonstrates how issues such as climate change and sustainability will shape the future.

This pioneering volume provides a blueprint for managing the challenges of ocean conservation using marine historical ecology—an interdisciplinary area of study that is helping society to gain a more in-depth understanding of past human-environmental interactions in coastal and marine ecosystems and of the ecological and social outcomes associated with these interactions. Developed by groundbreaking practitioners in the field, Marine Historical Ecology in Conservation highlights the innovative ways that historical ecology can be applied to improve conservation and management efforts in the oceans. The book focuses on four key challenges that confront marine conservation: (1) recovering endangered species, (2) conserving fisheries, (3) restoring ecosystems, and (4) engaging the public. Chapters emphasize real-world conservation scenarios appropriate for students, faculty, researchers, and practitioners in marine science, conservation biology, natural resource management, paleoecology, and marine and coastal archaeology. By focusing on success stories and applied solutions, this volume delivers the required up-to-date science and tools needed for restoration and protection of ocean and coastal ecosystems.

A book that emphasized the concept of wildlife habitat for a generation of students and professionals is now available to even more readers. "Habitat" is probably the most common term in ecological research. Elementary school students are introduced to the term, college students study the concept in depth, hunters make their plans based on it, nature explorers chat about the different types, and land managers spend enormous time and money modifying and restoring habitats. Although a broad swath of people now have some notion of what habitat is, the scientific community has by and large failed to define it concretely, despite repeated attempts in the literature to come to meaningful conclusions regarding what habitat is and how we should study, manipulate, and ultimately conserve it. Wildlife Habitat Conservation presents an authoritative review of the habitat concept, provides a scientifically rigorous definition, and emphasizes how we must focus on those critical factors contained within what we call habitat. The result is a habitat concept that promises long-term persistence of animal populations. Key concepts and items in the book include: • Rigorous and standard conceptual definitions of wildlife and their habitat. • A discussion of the essential integration of population demographics and population persistence with the concept of habitat. • The importance of carryover and lag effects, behavioral processes, genetics, and species interactions to our understanding of habitat. • An examination of spatiotemporal heterogeneity, realized through fragmentation, disruption to eco-evolutionary processes, and alterations to plant and animal assemblages. • An explanation of how anthropogenic effects alter population size and distribution (isolation), genetic processes, and species diversity (including exotic plants and animals). • Advocacy of proactive management and conservation through predictive modeling, restoration, and monitoring. Each chapter is accessibly written in a style that will be welcomed by private landowners and public resource managers at local, state, and federal levels. Also ideal for undergraduate and graduate natural resource and conservation courses, the book is organized perfectly for a one-semester class. Published in association with The Wildlife Society.

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.

Many estuaries are located in urbanized, highly engineered environments. Cohesive sediment plays an important role due to its link with estuarine health and ecology. An important ecological parameter is the suspended sediment concentration (SSC) translated into turbidity levels and sediment budget. This study contributes to investigate and forecast turbidity levels and sediment budget variability at San Francisco Bay-Delta system at a variety of spatial and temporal scales applying a flexible mesh process-based model (Delft3D FM). It is possible to have a robust sediment model, which reproduces 90% of the yearly data derived sediment budget, with simple model settings, like applying one mud fraction and a simple bottom sediment distribution. This finding opens the horizon for modeling less monitored estuaries. Comparing two case studies, i.e. the Sacramento-San Joaquin Delta and Alviso Slough, a classification for estuaries regarding the main sediment dynamic forcing is proposed: event-driven estuary (Delta) and tide-driven estuary (Alviso Slough). In the event-driven estuaries, the rivers are the main sediment source and the tides have minor impact in the net sediment transport. In the tide-driven estuaries, the main sediment source is the bottom sediment and the tide asymmetry defines the net sediment transport. This research also makes advances in connecting different scientific fields and developing a managerial tool to support decision making. It provides the basis to a chain of models, which goes from the hydrodynamics, to suspended sediment, to phytoplankton, to fish, clams and marshes.
