Book excerpt: Excerpt from Research and a Land Management Model for Southern California Watersheds Emergency sowing of herbaceous plants soon after a fire is an accepted practice in southern California watersheds. The purpose of this first aid treatment is to establish a temporary cover for protection of the watershed while the brush is slowly re covering. Although reasons for sowing denuded watersheds are obvious, the effects of sowing have never been quantitatively measured. Does the added cover pay in terms of reduced sedi ment in the stream channels? Are more expensive and more effective revegetation measures justified? The burned water sheds of the experimental forest should answer these questions. Annual species are usually sown because annuals are hardy and rese'ed themselves each year. The seed is abundant and cheap. For years black mustard was the most commonly sown species. In the last 6 years it has been largely replaced by common ryegrass in southern California, but on San Gabriel water sheds the two species have been sown in mixtures. Two other annuals-wimmera ryegrass and Blando brome-are now being used in some sowings. Which of the annuals provides the best cover on different sites? This is another question being studied. Deep - rooted perennial grasses also have been suggested for emergency temporary cover. They are commonly sown where permanent cover is desired, but perennials have never been widely tested on burned-over southern California watersheds. They are now being compared with annuals in the experimental watersheds to see if they provide better cover, especially at upper elevations too cold for good growth of annuals. The comparisons include tests of individual species and mixtures of species as both emer genoy and permanent cover. From October 23 to November 29, a total of acres were sown by helicopter within and adjacent to the experimental forest. An additional 83 acres were sown by hand, and 29 acres were sown with a heavy duty rangeland drill. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2013-06-29 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the result of an invited symposium titled "Integrated Land-Use and Environmental Models: A Survey of Current Applications and Research" that was held in October 2000 at Arizona State University. The idea for the symposium arose from a belief held by many academics that we are at the watershed of a new generation of models that are more dynamic, more pragmatic, more interdiscipli nary, and more amenable to collaborative decision making. Several academics and professionals engaged in urban research had long realized that domain-specific knowledge was inadequate for understanding and managing urban growth. While interdisciplinary approaches have become critical in most social research, one general area of knowledge that stands out as having the most wide-ranging impact on current urban modeling efforts is the field comprised of environmental sciences and ecology. The symposium offered a forum for academics and professionals engaged in urban and ecological modeling to exchange ideas and experiences, specifically in areas that overlapped urban and environmental issues. The contri butions to this volume highlight the progress made in the various efforts to build integrated urban and environmental models. More importantly, each chapter shows how ideas have diffused across disciplinary boundaries to create better policy-relevant models. In addition, this book outlines some promising areas of research that could make important contributions to the field of urban and envi ronmental modeling. Integrated thinking about urban and environmental issues has been fundamental to the concept of sustainability.

Download or read book Mediterranean Type Ecosystems written by Francesco di Castri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: No other disjunct pieces of land present such striking similarities as the widely sepa 1 rated regions with a mediterranean type of climate, that is, the territories fringing the Mediterranean Sea, California, Central Chile and the southernmost strips of South Mrica and Australia. Similarities are not confined to climatic trends, but are also reflected in the physiognomy ofthe vegetation, in land use patterns and frequently in the general appearance of the landscape. The very close similarities in agricultural practices and sometimes also in rural settlements are dependent on the climatic and edaphic analogies, as well as on a certain commonality in qdtural history. This is certainly true for the Mediterranean Sea basin which in many ways represents a sort of ecological-cultural unit; this is also valid for CaUfornia and Chile, which were both settled by Spaniards and which showed periods of vigorous commercial and cultural interchanges as during the California gold rush. One other general feature is the massive interchange of cultivated and weed species of plants that has occurred between the five areas of the world that have a mediterranean-type climate, with the Mediterranean basin region itself as a major source. In spite of their limited territorial extension, probably no other parts of the world have played a more fundamental role in the history of mankind. Phoenician, Etruscan, Hellenic, Jewish, Roman, Christian andArab civilizations, among others,haveshapedmanyofman's present attitudes, including his position and perception vis-a-vis nature.
