Taschenbuch. Zustand: Neu. Neuware - This study synthesizes a diverse array of data to examine the ecological patterns, ecosystem functions, and hydrology that characterized a central portion of the Laguna de Santa Rosa during the mid-19th century, and to analyze landscape changes over the past 150 years. The primary purpose of this study was to help guide restoration actions and other measures aimed at reducing nutrient loads within this portion of the Laguna de Santa Rosa watershed.…

Taschenbuch. Zustand: Neu. Neuware - This study examines the historical hydrology and ecology of the Petaluma River watershed prior to major Euro-American modification, and analyzes landscape changes over the past two centuries. Synthesizing information from hundreds of archival documents, the research examines the historical form and function of wetland, riparian, and aquatic habitats and stream channels throughout the watershed, providing insights into habitat extent and distribution, streamflow and sediment dynamics, vegetation composition, wildlife support, and landscape change. Findings from this research can be used to help set restoration targets and to prioritize multi-benefit opportunities to restore wildlife habitat, enhance flood protection, increase groundwater recharge, and improve sediment management.…

Taschenbuch. Zustand: Neu. Neuware - The Santa Ana River is one of the most recognizable landmarks in Riverside. Providing water, flood conveyance, wildlife habitat, and recreational and educational opportunities, the river is a vital resource for both people and ecological communities in the region. The Santa Ana River historically occupied a broad and dynamic river corridor characterized by a diverse mix of riparian and wetland habitats; surrounding areas were dominated by extensive sage scrub and forbland communities. Over the past two centuries, however, the natural functioning of the river has been heavily modified through channelization, levees, dam construction, and other impacts. Over 80% of the native habitat within the study area has been converted to developed and disturbed land, including approximately half of the historical extent of riparian forest and scrub.While the Santa Ana River and its surroundings have changed drastically since the mid-19th century, this modified landscape still has the potential to support a healthy and resilient ecosystem. This report synthesizes information from both historical and present-day landscape analyses to develop multi-benefit strategies and recommendations that support ecological processes, meet present-day species needs, and foster livable communities with connection to nature and its benefits.…

Taschenbuch. Zustand: Neu. Neuware - The Peninsula Watershed has been integral to the story of San Francisco's growth ever since the Gold Rush. The rapid influx of settlers to San Francisco during the Gold Rush spurred a sudden demand for a reliable water source, which led to the formation of the Spring Valley Water Works (later purchased by the Spring Valley Water Company [SVWC]) in 1858 (Hanson 2005 ). Over the subsequent 70 years, SVWC bought up large swaths of land on the Peninsula, and constructed a complex system of dams, tunnels, and pipes to capture and transport water to San Francisco. Within the Peninsula Watershed, this system includes the Crystal Springs and San Andreas reservoirs, located in the San Andreas Creek, Laguna Creek, and Upper San Mateo Creek basins along the San Andreas Fault; and Pilarcitos Reservoir the west, located in the Pilarcitos Creek Basin along the Pilarcitos Fault.…
