The natural resources of San Diego Bay; Their status and future

The study of the natural resources of San Diego Bay is a part of a high priority inventory and assessment program conducted by the Department of Fish and Game. This report is a guide for citizens, planners, administrators, and all others interested in the use and development of coastal lands and waters. It documents the status and future of natural resources that should be a part of the inheritance of future generations. References appended provide the interested and concerned reader with sources of more specific information. One of a scheduled series, this publication follows similar documents on Upper New-port Bay (Orange County), Goleta Slough (Santa Barbara County), Bolinas Lagoon (Marin County), and Elkhorn Slough (Monterey County). Preparation of this report has been supported by Fish and Wild- Life Preservation funds and by Pittman-Robertson Federal Aid to wildlife programs. (124 pp.

The natural resources of Agua Hedionda Lagoon

This report has been prepared under contract to and fully funded by the Office of Biological Services of the U. S. Fish and Wildlife Service. The goals and purpose of this federal office are to review the impact on fish and wildlife resources of land, mineral and water development practices, such as offshore oil and gas exploration, development and production; construction of inshore pipeline canals and refineries; power plant construction/operation and urban development. This report, and five other southern California reports, covering Carpinteria Marsh (Santa Barbara County), Anaheim Bay-Huntington Harbor (Orange County), Mugu Lagoon (Ventura County), the Northern Santa Barbara County Coastal Wetlands, and the Nipomo Dunes and Wetlands (San Luis Obispo County), are scheduled to be part of the Department's "Coastal Wetland Series" (see inside front cover).

The natural resources of Carpinteria Marsh: their status and future

The purpose of this report is: 1) to document the natural resources of Carpinteria Marsh, 2) outline the uses those resources receive, 3) enumerate the problems and conflicts of use that affect those resources, and 4) recommend measures that will protect and enhance the marsh and its resources. It is intended as a guide for citizens, planners and administrators of all private and public entities interested in the status and future of the marsh. This report has been prepared under contract to and fully funded by the Office of Biological Services of the U.S. Fish and Wildlife Service. The goals and purpose of this federal office are to review the impact on fish and wildlife resources of land, mineral and water development practices, such as offshore oil and gas exploration, development and production; construction of inshore pipeline canals and refineries; power plant construction/operation and urban development. This report, and five other southern California reports, covering Agua Hedionda (San Diego County), Anaheim Bay-Huntington Harbor (Orange County), Mugu Lagoon (Ventura County), the Northern Santa Barbara County Coastal Wetlands and the Nipomo Dunes and Wetlands (San Luis Obispo County), are scheduled to be part of the Department's "Coastal Wetland Series" that includes reports on the natural resources of Upper Newport Bay (Orange County), Goleta Slough (Santa Barbara county), Bolinas Lagoon (Marin County), Elkhorn Slough (Monterey County), San Diego Bay and Los Penasquitos Lagoon (San Diego County), Morro Bay (San Luis Obispo County), Humboldt Bay and the Eel River Delta (Humboldt County), Lake Earl and the Smith River Delta (Del Norte County) and Bodega Harbor (Sonoma County).

The natural resources of Bolinas Lagoon: their status and future

This publication is an integral part of the Department's high-priority inventory and assessment of coastal marshland and tideflat resources. It is intended as a guide for citizens, planners, administrators, and all others interested in the use and development of coastal lands and waters. Although the resources and problems of Bolinas Lagoon have probably been the subject of more biological and physical investigations than any small estuarine area of the California coast, many of the pertinent reports and information are not readily available to the public. Consequently, it is one purpose of this report to summarize the lagoon's history, ecological attractions, educational values and the problems facing its continued existence. At the same time, it should provide concerned citizens with a knowledge of the sources of additional and more specific information. Publication of this report is consistent with the obligation of the Department of Fish and Game to do everything in its power to protect and maintain the State's fish and wildlife resources. Therefore, its purpose transcends local issues on pollution and development, and the Department is, in fact, submitting a report to the people on the status and future of part of its inheritance and the dowry of coming generations. The report is the third of a scheduled series. It follows similar releases on Upper Newport Bay (Orange County) and Goleta Slough (Santa Barbara county) in March and June of 1970. Documentation of the resources of other critical areas is in progress. There will be future reports of this nature on Elkhorn Slough, Morro Bay, Tomales Bay, Humboldt Bay, and highly threatened marshlands in southern California. (137 pp.

The natural resources of San Dieguito and Batiquitos Lagoons

The California Department of Fish and Game has played a central role in attempting to protect and enhance the remaining 25% of southern California wetlands which have survived the ingress of urbanization and commercial development since 1900 (U.S. Dept. Interior, 1972). To this end, the Department has published a series of reports documenting California's coastal wetlands resources, including four covering wetlands in southern California (Upper Newport Bay, Frey et al., 1970; Goleta Slough, Speth et al., 1970; Los Penasquitos Lagoon, Mudie et al., 1974; and San Diego Bay, Browning et al., 1973). The following report is an extension of that effort. (131pp.

Natural resources of Lake Earl and Smith River Delta

The Lake Earl/Smith River Delta area is a key coastal wetland situated in northern California. The Lake and Delta have retained much of their value to wildlife and serve as an important link in a chain of such wetlands that extend southward along the Pacific Ocean from Alaska to South America. Millions of water-associated birds of the Pacific Flyway utilize these areas as feeding and resting stops along their migration paths. In California, these wetlands also serve as a significant portion of the available wintering grounds for a major share of the birds within the flyway. The Smith River is also one of the State's most productive salmon and steelhead streams. Anadromous fish produced here provide thousands of angler use days to sport fishermen and contribute substantially to the commercial fishing catch off the northern coast. Because of the importance of coastal wetlands to the fish and wildlife of California, the Department of Fish and Game has initiated a high priority statewide inventory and assessment of these wetlands. This publication is an integral part of that program. This report identifies specific resources and uses; directs attention to problems; and recommends courses of action needed to insure resource protection. It is intended as a guide for citizens, planners, administrators and other interested in the use and development of California's coastal land and waters. (132pp.

Natural resources of the Eel River delta

The purpose of this report is to document the natural resources of the Eel River Delta, Humboldt County; to outline and evaluate the problems and conflicts of use that affect those resources; and, to recommend measures that will protect and enhance the Delta and its environs. The Eel River Delta is an important segment of the coastal wetlands of California. Over two-thirds of the State's original bays, estuaries, lagoons and coastal marshes has already been lost to development and reclamation. Because of the importance of coastal wetland ecosystems to fish and wildlife, the Department has initiated a high priority, statewide inventory of the remaining wetland areas. This publication is an integral part of that program and one of a "Coastal Wetland Series" that includes reports on Upper Newport Bay, Orange County; Goleta Slough, Santa Barbara County; Bolinas Lagoon, Marin County; Elkhorn Slough, Monterey County; San Diego Bay, San Diego County; Humboldt Bay, Humboldt County; Los Penasquitos Lagoon, San Diego County; and Morro Bay, San Luis Obispo County.

The natural resources of Los Penasquitos Lagoon

The purpose of this report is to document the natural resources of Los Penasquitos Lagoon, San Diego County; to outline and evaluate proposed developments affecting those resources; and to recommend measures that will protect and enhance the lagoon and its environs. The necessity for a report of this nature has become apparent with the progressive destruction of California's coastal wetlands over the past fifty years. These wetland resources, which are virtually irreplaceable, are essential to the continued existence of many forms of resident fish and wildlife and to the preservation of migratory shorebirds and waterfowl. Approximately 60 percent of the tidal wetlands in California has already been destroyed (Speth, 1970); and, it is estimated that only 10 percent is left of the original acreage of coastal marshland in San Diego County. The future of the remaining wetland habitats continues to be threatened. There is an urgent need, therefore, for sound planning to protect these wetlands and to prevent their otherwise inevitable disappearance as a valuable natural resource. (100pp.

In vitro Studies on Metabolism of Salvinorin A

Microbial transformation of natural products is a well established model for mammalian metabolism. Salvinorin A, a diterpenoid isolated from the hallucinogenic mint Salvia divinorum Epling & Játiva-M (Lamiaceae), is a potent non-nitrogenous κ-opioid receptor agonist. The metabolism of salvinorin A has still not yet been well established. Thirty fungal species were screened for the ability to metabolize salvinorin A. We observed that salvinorin A undergoes fast hydrolysis of the acetate group at carbon atom C2, resulting in formation of the pharmacologically inactive product, salvinorin B. Ex vivo experiments were also performed using organelle fractions isolated from rat liver and brain. Crude tissue homogenate and individual organelles show that the primary route of salvinorin A metabolism is hydrolysis to salvinorin B. No metabolic transformation of salvinorin B was observed in these studies

The natural resources of Elkhorn Slough: their present and future use

This report summarizes the history of the slough, ecological attractions, educational value, and problems facing its continued existence. Appended references provide the interested and concerned citizen with sources of more specific information. As a result of the initial survey of estuarine areas of California (California Department of Fish and Game, 1969), the critical status of the coastal marshes became obvious. This report on Elkhorn Slough is part of the high priority inventory and assessment of coastal wetlands by the Department of Fish and Game, and it is intended as a guide for citizens, planners, administrators, and all others interested in the use and development of coastal lands and waters. As such, this report transcends local issues on pollution and development and, in fact, documents the status and future of natural resources that should be a part of the inheritance of following generations. This publication is one of a scheduled series. It follows similar documents on Upper Newport Bay (orange county), Goleta Slough (Santa Barbara County) and the Bolinas Lagoon (Marin county).
