This book was released on 1988 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1982 statistics on the use of family planning and infertility services presented in this report are preliminary results from Cycle III of the National Survey of Family Growth (NSFG), conducted by the National Center for Health Statistics. Data were collected through personal interviews with a multistage area probability sample of 7969 women aged 15-44. A detailed series of questions was asked to obtain relatively complete estimates of the extent and type of family planning services received. Statistics on family planning services are limited to women who were able to conceive 3 years before the interview date. Overall, 79% of currently mrried nonsterile women reported using some type of family planning service during the previous 3 years. There were no statistically significant differences between white (79%), black (75%) or Hispanic (77%) wives, or between the 2 income groups. The 1982 survey questions were more comprehensive than those of earlier cycles of the survey. The annual rate of visits for family planning services in 1982 was 1077 visits /1000 women. Teenagers had the highest annual visit rate (1581/1000) of any age group for all sources of family planning services combined. Visit rates declined sharply with age from 1447 at ages 15-24 to 479 at ages 35-44. Similar declines with age also were found in the visit rates for white and black women separately. Nevertheless, the annual visit rate for black women (1334/1000) was significantly higher than that for white women (1033). The highest overall visit rate was for black women 15-19 years of age (1867/1000). Nearly 2/3 of all family planning visits were to private medical sources. Teenagers of all races had higher family planning service visit rates to clinics than to private medical sources, as did black women age 15-24. White women age 20 and older had higher visit rates to private medical services than to clinics. Never married women had higher visit rates to clinics than currently or formerly married women. Data were also collected in 1982 on use of medical services for infertility by women who had difficulty in conceiving or carrying a pregnancy to term. About 1 million ever married women had 1 or more infertility visits in the 12 months before the interview. During the 3 years before interview, about 1.9 million women had infertility visits. For all ever married women, as well as for white and black women separately, infertility services were more likely to be secured from private medical sources than from clinics. The survey design, reliability of the estimates and the terms used are explained in the technical notes.

Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Download or read book The Biology and Utilization of Shrubs written by Cyrus McKell and published by Elsevier. This book was released on 2012-12-02 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology and Utilization of Shrubs brings together the wide range of information about shrubs from many disciplines and world locations. The book is organized into seven parts. Part I describes the major shrublands found on each of the vegetated continents. It provides an overview of the dominant shrubland types as well as the associated features of soil and climate that influence the geographic distribution of major shrub species. Part II discusses environmental influences and plant responses. Part III considers the range of genetic diversity for important traits and how these may vary in different habitats. Part IV discusses the effects of stress on physiological processes of shrubs, and the kinds of strategies shrubs employ to meet physiological stress. Part V offers evidence to support the claim that the many virtues of shrubs provide a basis for sustaining shrub use for livestock fodder, wildlife habitat, reclamation and erosion control, fuel, and naturalized landscaping. Part VI outlines methods for collecting and processing seeds from natural stands or from superior genotypes planted in seed production orchards. Part VII describes cultural adaptation to shrub use in a livestock-dominated primitive culture, followed by a detailed economic analysis of establishing shrub plantations to improve livestock production.

Download or read book Roadside Use of Native Plants written by Bonnie Harper-Lore and published by Island Press. This book was released on 2000-09 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published by the U.S. Department of Transportation's Federal Highway Administration (FHWA), Office of Natural Environment to promote the planting and care of native plants along highway rights-of-way, this unique handbook provides managers of roadsides and adjacent lands with the information and background they need to make site-specific decisions about what kinds of native plants to use, and addresses basic techniques and misconceptions about using native plants. It brings together in a single volume a vast array of detailed information that has, until now, been scattered and difficult to find.The book opens with eighteen short essays on principles of ecological restoration and management from leading experts in the field including Reed F. Noss, J. Baird Callicott, Peggy Olwell, and Evelyn Howell. Following that is the heart of the book, more than 500 pages of comprehensive state-by-state listings that offer: a color map for each state with natural vegetations zones clearly marked comprehensive lists of native plants, broken down by type of plant (grasses, forbs, trees, etc.) and including both scientific and common names, with each list having been verified for completeness and accuracy by the state's natural heritage program contact names, addresses, and phone numbers for obtaining current information on invasive and noxious species to be avoided resources for more information, including contact names and addresses for local experts in each state The appendix adds definitions, bibliography, and policy citations to clarify any debates about the purpose and the direction of the use of native plants on roadsides.Roadside Use of Native Plants is a one-of-a-kind reference whose utility extends far beyond the roadside, offering a toolbox for a new aesthetic that can be applied to all kinds of public and private land. It can help lead the way to a cost-effective ecological approach to managing human-designed landscapes, and is an essential book for anyone interested in establishing or restoring native vegetation.
Download or read book Low Volume Roads Engineering Best Management Practices Field Guide written by Gordon Keller and published by . This book was released on 2023-11-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Low-Volume Roads Engineering Best Management Practices Field Guide is intended to provide an overview of the key planning, location, design, construction, and maintenance aspects of roads that can cause adverse environmental impacts and to list key ways to prevent those impacts. Best Management Practices are general techniques or design practices that, when applied and adapted to fit site-specific conditions, will prevent or reduce pollution and maintain water quality. BMPs for roads have been developed by many agencies since roads often have a major adverse impact on water quality, and most of those impacts are preventable with good engineering and management practices. Roads that are not well planned or located, not properly designed or constructed, not well maintained, or not made with durable materials often have negative effects on water quality and the environment.
Download or read book Wildland Fire in Ecosystems written by and published by Forest Service. This book was released on 2008 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This state-of-knowledge review of information on relationships between wildland fire and nonnative invasive plants can assist fire managers and other land managers concerned with prevention, detection, and eradication or control of nonnative invasive plants. The 16 chapters in this volume synthesize ecological and botanical principles regarding relationships between wildland fire and nonnative invasive plants, identify the nonnative invasive species currently of greatest concern in major bioregions of the United States, and describe emerging fire-invasive issues in each bioregion and throughout the nation. This volume can help increase understanding of plant invasions and fire and can be used in fire management and ecosystem-based management planning. The volume's first part summarizes fundamental concepts regarding fire effects on invasions by nonnative plants, effects of plant invasions on fuels and fire regimes, and use of fire to control plant invasions. The second part identifies the nonnative invasive species of greatest concern and synthesizes information on the three topics covered in part one for nonnative invasives in seven major bioregions of the United States: Northeast, Southeast, Central, Interior West, Southwest Coastal, Northwest Coastal (including Alaska), and Hawaiian Islands. The third part analyzes knowledge gaps regarding fire and nonnative invasive plants, synthesizes information on management questions (nonfire fuel treatments, postfire rehabilitation, and postfire monitoring), summarizes key concepts described throughout the volume, and discusses urgent management issues and research questions.
Download or read book Evaluating the Effectiveness of Postfire Rehabilitation Treatments written by Peter R. Robichaud and published by . This book was released on 2000 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spending on postfire emergency watershed rehabilitation has increased during the past decade. A west-wide evaluation of USDA Forest Service burned area emergency rehabilitation (BAER) treatment effectiveness was undertaken as a joint project by USDA Forest Service Research and National Forest System staffs. This evaluation covers 470 fires and 321 BAER projects, from 1973 through 1998 in USDA Forest Service Regions 1 through 6. A literature review, interviews with key Regional and Forest BAER specialists, analysis of burned area reports, and review of Forest and District monitoring reports were used in the evaluation. The study found that spending on rehabilitation has increased to over $48 million during the past decade because the perceived threat of debris flows and floods has increased where fires are closer to the wildland-urban interface. Existing literature on treatment effectiveness is limited, thus making treatment comparisons difficult. The amount of protection provided by any treatment is small. Of the available treatments, contour-felled logs show promise as an effective hillslope treatment because they provide some immediate watershed protection, especially during the first postfire year. Seeding has a low probability of reducing the first season erosion because most of the benefits of the seeded grass occurs after the initial damaging runoff events. To reduce road failures, treatments such as properly spaced rolling dips, water bars, and culvert reliefs can move water past the road prism. Channel treatments such as straw bale check dams should be used sparingly because onsite erosion control is more effective than offsite sediment storage in channels in reducing sedimentation from burned watersheds. From this review, we recommend increased treatment effectiveness monitoring at the hillslope and sub-catchment scale, streamlined postfire data collection needs, increased training on evaluation postfire watershed conditions, and development of an easily accessible knowledge base of BAER techniques.
