    Agron Bioenergy 860 West Beach Street Watsonville CA 95076 Office 831 383 1300: Fax 831 786 8508 George Dondero Executive Director Santa Cruz County Regional Transportation Commission 1523 Pacific Ave Santa Cruz, CA 95060 6/7/2018 Dear Mr Dondero, We are writing to you to express our serious concern about the status of the short rail line from Santa Cruz to Watsonville. The rail line is out of service as the operator cannot afford to inspect nor repair it. Rail is essential to our business, so we urge you to support the Sant Cruz RTC in approving Progressive Rail as the new operator of the short line so normal rail service can resume. Agron Bioenergy owns a multi-million-dollar Biodiesel plant on West Beach street in the disadvantaged city of Watsonville. The plant processes waste animal fats into fuel. Agron’s business plan relies on moving large amounts of freight by rail; the Agron site was purchased with the ability to spot 6 railcars for offload in mind. The anticipated rail traffic by late Q3 is around 20 railcars of raw materials a week. Agron’s plant is one of the largest biodiesel plants in California, and as such it supports both the reductions in criteria emissions and the reduction in greenhouse gases that are central to California’s emissions strategy for community and environmental health. Agron will reduce the overall carbon dioxide emissions in California by over 10000 metric tons in 2019. Agron anticipates producing 12m gallons of fuel; to be sold Watsonville. The fuel sales will bring extensive tax revenue to the city.

The study seeks to determine whether there have been discernable changes in vegetation alliances (communities), spatially or in type, within a 110-acre Study Area from the early twentieth century to the present day and how the changes compare with other similar historical analyses in California. Historical farming and ranching uses of the area are researched, and two family case studies are presented as paradigms of potential changes to vegetation as well as the connectivity with the larger socioeconomic context of Italian immigration into California. Examination of the vegetation alliances over the course of the historical study period utilizes several types of historical imagery, including twentieth-century aerial photography, ground level photography and nineteenth-century maps.

  • Biases in Estimation of Insect Herbivory from Herbarium Specimens Mikhail V
    www.nature.com/scientificreports OPEN Biases in estimation of insect herbivory from herbarium specimens Mikhail V. Kozlov 1*, Irina V. Sokolova2, Vitali Zverev 1, Alexander A. Egorov3, Mikhail Y. Goncharov4 & Elena L. Zvereva 1 Information regarding plant damage by insects in the past is essential to explore impacts of climate change on herbivory. We asked whether insect herbivory measured from herbarium specimens refects the levels of herbivory occurring in nature at the time of herbarium sampling. We compared herbivory measurements between herbarium specimens collected by botany students and ecological samples collected simultaneously by the authors by a method that minimized unconscious biases, and asked herbarium curators to select one of two plant specimens, which difered in leaf damage, for their collections. Both collectors and curators generally preferred specimens with lesser leaf damage, but the strength of this preference varied among persons. In addition, the diferences in measured leaf damage between ecological samples and herbarium specimens varied among plant species and increased with the increase in feld herbivory. Consequently, leaf damage in herbarium specimens did not correlate with the actual level of herbivory. We conclude that studies of herbarium specimens produce biased information on past levels of herbivory, because leaf damage measured from herbarium specimens not only underestimates feld herbivory, but it is not proportional to the level of damage occurring in nature due to multiple factors that cannot be controlled in data analysis. Te data on the intensity of biotic interactions during pre-industrial times are badly needed for evaluation of the extent of the pervasive infuence of human-induced global environmental changes on organisms, populations, communities and entire ecosystems.

A new species from the genus Digitivalva Gaedike, 1 970 is described from Greece, Digitivalva seligeri sp. n. This species belongs to the species group eglanteriella. Keys, based on the adult characters and male and female genitalia, that allow separation of the new species from the other species of its species group, are provided. Introduction My friend Rudi Seliger (Schwalmtal) sent me undetermined material from Greece, which contains a small series of a species from the genus Digitivalva Gaedike, 1970. After a careful examination, it became obvious that these specimens belong to a new species. This species is described below. The genus Digitivalva is one of four genera in the family Acrolepiidae. Hitherto 92 species of acrolepiids are known worldwide. According to Dudgale et al. (1998), this family is a member ofthe putative clade Plutellidae + Acrolepiidae + Glyphipterigidae + (Heliodinidae + Bedellidae + Lyonetiidae). The likely family autapomorphies (Kyrki 1984) include the details of the male genitalia (for example, the reduction of the tegu- men, teguminal processes, and gnathos, and the basal widening of the phallus) and the stalking of the hindwing veins M, + M2 and M3 + CuAj.

We hope that this will make our report more easily accessible, since you may chose to store it on your hard disk. There are also a 58 pages of Appendices that supplement this report. They can be viewed / downloaded from our FTP dropbox at ftp://147.49.50.52/dropbox/Balciunas/. The good news is that by the end of 2006, we had reached the milestone of completing our host range testing of our two most promising potential biological control agents for Cape ivy, the gall fly, Parafreutreta regalis, and the stem-boring moth, Digitivalva delaireae. We have tested more than 80 species of plants, and neither of our candidate agents was able to complete development on anything other than their Cape ivy host.{See sections II & III] We have collated our results, and are preparing a formal ‘petition’ seeking permission to release both of these agents in the field. This ‘petition’ will be submitted to TAG during the second quarter of 2007. We hope to receive a positive recommendation from TAG within 6 months. The outlook for receiving a release permit from USDA-APHIS-PPQ has improved, but is still not clear.

  • 240 Years of Ranching Historical Research, Field Surveys, Oral
    240 Years of Ranching Historical Research, Field Surveys, Oral Interviews, Significance Criteria, and Management Recommendations for Ranching Districts and Sites in the San Diego Region By Sue A. Wade Stephen R. Van Wormer Heather Thomson September 8, 2009 i ABSTRACT Livestock have grazed on the grasslands of Southern California from the time the first Europeans arrived in the 1700s until the present day. Within a few years of the establishment of the first Spanish missions, thousands of horses, cattle, and sheep grazed on the coastal mesas, inland valleys, and mountain foothills. After the Mexican revolution in 1821 and the subsequent secularization of the missions, the California rancheros continued raising livestock on the open range. Thus, during the Spanish and Mexican periods, from the 1770s until the 1840s, the base economy of California depended on open-range cattle. During this time, cattle were primarily raised for their hides, some used locally, but the majority brought by the thousands to the coastal ports and traded to Americans for transport to the United States East Coast. After the American takeover of California in 1848 and the discovery of gold in Northern California the following year, the cattle industry continued to prosper by producing meat to feed the thousands of emigrants and gold-rushers in Northern California. Although impacted by droughts in the 1860s, the cattle meat industry continued to be viable until the 1880s. In the late nineteenth century, as a result of the rampant promotion of Southern California by land speculators and several years of exceptional rains that supported dry-land farming, much of the prime agricultural land of Southern California was homesteaded by American farming families.
