Government agencies that develop infrastructure such as roads, waterworks, and energy delivery often impact natural ecosystems, but they also have unique opportunities to contribute to the conservation of regional natural resources through compensatory mitigation. Infrastructure development requires a planning, funding, and implementation cycle that can frequently take a decade or longer, but biological mitigation is often planned and implemented late in this process, in a project-by-project piecemeal manner. By adopting early regional mitigation needs assessment and planning for habitat-level impacts from multiple infrastructure projects, agencies could secure time needed to proactively integrate these obligations into regional conservation objectives.... |

Summer seed mortality (SSM) has occurred yearly in Tomales Bay, California since 1993. SSM has resulted in up to 90% cumulative losses, and has been associated with extreme temperature, phytoplankton blooms, and an oyster herpesvirus. In this study, three stocks of Pacific oysters were planted at three sites in California (Inner Tomales Bay, Outer Tomales Bay, and Bodega Harbor) in October of 2000 (Fall) and April of 2001 (Spring) and monitored for mortality, growth, and health status. In April of 2001, a similar study was conducted in Totten Inlet, WA state using cohorts of oysters planted in California; animals were monitored for mortality and growth. Temperature data were collected at all sites; phytoplankton abundance data were collected at the... |

Most research studies related to biodiversity offsetting have focused on governance systems already in place in the terrestrial realm – these studies tend to rely on an approach of organizational economics, in particular in relation to mitigation banking schemes. In this study, emerging marine offsetting governance systems has been analyzed using the Actor–Network Theory (ANT) with the aim of highlighting the key elements that enable the emergence of marine offsetting tools. The ANT framework has been applied to four case studies in California using data collected in a field study that consisted of interviewing 30 stakeholders working closely with the issue of marine offsetting. Employing ANT allowed to ascertain the role of commonly studied elements such... |

Cysts (encysted gastrula embryos) of <i>Artemia franciscana</i> collected from salterns in San Francisco Bay, California, USA (SF) were inoculated into much warmer growth ponds in the Mekong Delta region of Vietnam (V) in 1996. V adults arising directly from these cysts during 17 April to 15 May produced their own cysts, which were collected, processed and stored until shipped to the USA for study. Adults grown in the laboratory from SF cysts (those used for the inoculation) were less resistant to high temperature than adults cultured from V cysts. V cysts produced heat-resistant adults, even though cultured under the same laboratory conditions as SF animals, at much lower temperatures than they ever experienced in Vietnam. Differences in... |

Different <i>Artemia</i> cyst samples harvested from the San Francisco and the San Pablo Bay regions (California, USA), and suspect because of their poor nutritional performance in fish and crustacean farming, have been analyzed for their chlorinated hydrocarbon and fatty acid content. These results have been correlated with survival, growth, and biomass production of larvae of the marine crustacean <i>Mysidopsis bahia</i> Molenock fed those different <i>Artemia</i> in a standard culture test. Differences in chlorinated hydrocarbon content do not correlate with differences in mysid culture performance. Fatty acid profiles reveal three groups of <i>Artemia</i> batches with high, intermediate, and low levels of... |

We model a game between two players taking biosecurity actions and characterize the Nash equilibria and their properties for the cases of strategic complements and substitutes. Implications of the theoretical model are investigated using data for biosecurity behavior among producers participating in a livestock exhibition. Biosecurity actions with own benefits and lasting impacts in home communities exhibit a positive relationship with behavior of the producers from geographically close areas. The number and probabilities of biosecurity actions taken by exhibitors are positively associated with the number of animals exhibited and they vary among commercial and hobby producers and across species/types of commercial production. |

Citrus black spot (CBS) was discovered in March of 2010 near Immokalee in Collier County. CBS may adversely impact citrus growers both through demand and supply impacts. This paper has focused on the demand side of the equation. The analysis has also focused on Florida honey tangerines and the market in California. This market accounts for about 17.7% of Florida honey tangerine sales. If Florida product were banned from California in fear of CBS spreading there, the FOB price for Florida honey tangerines is estimated to decline by $3.48 to $4.40 per box, all else constant. The on-tree price would be expected to decline by the same amounts. However, with respect to production costs, all else would not be constant. Growers would be expected to bear... |

This paper examines the aggregate performance of California agriculture relative to Florida and U.S. agriculture, 1960-1993, the economics of the California raisin grape industry which uses large quantities of migratory labor for the grape harvest, and schools and schooling of farm workers' children in the Parlier area. The major conclusions are that the labor intensity of California (and Florida) agriculture has fallen much less than for the whole U.S., the raisin grape industry of the Central San Joaquin Valley is struggling due to labor availability and prospects of greater foreign competition, and schooling is one of the most promising routes to a better life for the children of adult farm workers. |

Proposals for reform of the federal multiple-peril crop insurance program for specialty crops seek to change fees for catastrophic (CAT) insurance from a nominal fifty-dollar per contract registration fee to an actuarially sound premium. Growers argue that this would cause a significant reduction in participation rates, thus impeding the program's goals of eventually obviating the need for ad hoc disaster payments and worsening the actuarial soundness of the program. The key policy issue is, therefore, empirical one - whether the demand for specialty crop insurance is elastic or inelastic. Previous studies of this issue using either grower or county-level field crop data typically treat the participation problem as either a discrete insure / don't insure... |

California’s nursery and floral industry is the largest in the United States with a farm value for product sales totaling $3.78 billion in 2009. When floral and nursery product sales are combined, the industry ranks second among all California agricultural products, following the dairy industry. Production is in 55 of California’s 58 counties, although 16 counties account for more than 87% of the value of production. San Diego County dominates the industry with annual sales over $1 billion in 2007, 2008, and 2009. Since its 2008 and 2009 sales increased while California’s statewide sales decreased, San Diego County increased its share of California sales from 26% in 2007 to 30.3% in 2009. California is the largest single retail market for lawn and garden... |

In recent decades, urban encroachment and increasing environmental regulation have impacted California’s dairy industry. A complicated set of environmental legislation affects dairies in the state, and can differ depending on location, creating the possibility for within-state pollution havens. This article details the regional, state, and federal environmental regulation of California’s dairy industry, and examines data to see if it matches a hypothesis of regulation affecting dairy location. Using county-year data, we show evidence of changing dairy location within the state matching times of local legislative action. The Central Valley gained production, while the more regulated and urban-affected Los Angeles area lost. Large dairies have increased by... |
