Low-volume and Slow-burning Vegetation for Planting on Clearings in California Chaparral by Eamor C. Nord,Lisle R. Green Pdf
Vegetation that is low-growing and either low in volume, slow bwning, or both, is needed for reduction of fire hazard on fuelbreaks and other brush-cleared areas in California. Of over 50 shrub species and many grass species that were test planted, about 20 shrubs and an equal number of grasses were chosen for plot and field trials. Creeping sage, a few saltbushes. and a few grasses-mostly perennials-are adapted within the wide range of chaparral site conditions, and were successfully established by direct seedings as well as by other cultural methods on these sites. Shrub test results are tabulated and characteristics of each of the more promising species are described. With attention to usefulness for planting; techniques for collecting or treating seed to improve gennination and for propagating plants; and methods for establishing these plants on wildland sites.

Air Pollution by Photochemical Oxidants by Robert Guderian Pdf
Photochemical oxidants are secondary air pollutants formed under the influence of sunlight by complex photochemical reactions in air which contains nitrogen oxides and reactive hydrocarbons as precursors. The most adverse components formed by photochemical reactions in polluted air are ozone (0 ) 3 and peroxyacetyl nitrate (PAN), among many other products such as aldehydes, ketones, organic and inorganic acids, nitrates, sulfates etc. An analysis and evaluation of the available knowledge has been used to characterize the relationships among emissions, ambient air concentrations, and effects, and to identify the important controlling influences on the formation and effects of photochemical oxidants. The biological activity of photochemical oxidants was first clearly manifested during the early 1940's, when vegetation injury was observed in the Los Angeles Basin in the United States. Since that time, as a consequence of the increasing emissions of photochemical oxidant precursors, the photochemical oxidants have become the most important air pollutants in North America. In other parts of the world, for example South and Central America, Asia, and Australia, photo chemical oxidants threaten vegetation, particularly the economic and ecological performance of plant life. According to my knowledge, the first observations of ozone and PAN injury to vegetation in Europe were made by Dr. Ellis F. Darley (Statewide Air Pollution Research Center, University of California, Riverside, California) during a study visit (1963/64) to the Federal Republic of Germany.

Proceedings of the Second International Clean Air Congress by H.M. Englund,W.T. Beery Pdf
Proceedings of the Second International Clean Air Congress documents the information and experiences exchanged at the Second International Clean Air Congress held in Washington, D.C. on December 6-11, 1970. This book compiles technical papers of five representatives from the national non-governmental air pollution prevention association of Argentina, France, West Germany, Japan, and the United Kingdom that aims to determine how they might work together cooperatively to contribute to the conservation of the world's air resources The topics discussed include the Swedish experiences on sensory evaluation of odorous air pollutant intensities; chronic fluoride intoxication due to air pollution; and organic ozone reactions as singlet oxygen sources. The emission and control of air pollutants from the incineration of municipal solid wastes and gaseous plume diffusion about isolated structures of simple geometry are also covered. This publication is a good reference for environmentalists and students interested in the scientific, technological, and administrative aspects of air pollution control.

A two-stage shelterwood cutting, at 12 trees per acre, with site preparation, enhanced seedfall, regeneration, and residual growth at the Challenge Experimental Forest, north central California. Shelterwood trees produced 9.2 times more seed than trees in the control. Ponderosa pine regeneration numbered about 3700 seedlings per acre (9139 per ha) and tolerant conifers 600 seedlings (1482 per ha) after 5 years. Hardwood seedlings and sprouts also were abundant. Basal area growth rates for all species in nearly all diameter classes were greater in the shelterwood than in the control. The shelterwood cutting method is recommended for use in young-growth, mixed-conifer stands.

Lost Laborers in Colonial California by Stephen W. Silliman Pdf
Native Americans who populated the various ranchos of Mexican California as laborers are people frequently lost to history. The "rancho period" was a critical time for California Indians, as many were drawn into labor pools for the flourishing ranchos following the 1834 dismantlement of the mission system, but they are practically absent from the documentary record and from popular histories. This study focuses on Rancho Petaluma north of San Francisco Bay, a large livestock, agricultural, and manufacturing operation on which several hundredÑperhaps as many as two thousandÑNative Americans worked as field hands, cowboys, artisans, cooks, and servants. One of the largest ranchos in the region, it was owned from 1834 to 1857 by Mariano Guadalupe Vallejo, one of the most prominent political figures of Mexican California. While historians have studied Vallejo, few have considered the Native Americans he controlled, so we know little of what their lives were like or how they adjusted to the colonial labor regime. Because VallejoÕs Petaluma Adobe is now a state historic park and one of the most well-protected rancho sites in California, this site offers unparalleled opportunities to investigate nineteenth-century rancho life via archaeology. Using the Vallejo rancho as a case study, Stephen Silliman examines this California rancho with a particular eye toward Native American participation. Through the archaeological recordÑtools and implements, containers, beads, bone and shell artifacts, food remainsÑhe reconstructs the daily practices of Native peoples at Rancho Petaluma and the labor relations that structured indigenous participation in and experience of rancho life. This research enables him to expose the multi-ethnic nature of colonialism, counterbalancing popular misconceptions of Native Americans as either non-participants in the ranchos or passive workers with little to contribute to history. Lost Laborers in Colonial California draws on archaeological data, material studies, and archival research, and meshes them with theoretical issues of labor, gender, and social practice to examine not only how colonial worlds controlled indigenous peoples and practices but also how Native Americans lived through and often resisted those impositions. The book fills a gap in the regional archaeological and historical literature as it makes a unique contribution to colonial and contact-period studies in the Spanish/Mexican borderlands and beyond.
