Download or read book Watershed Condition Classification Technical Guide written by U.s. Department of Agriculture Forest Service and published by Createspace Independent Pub. This book was released on 2012-08-15 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Agriculture (USDA) Strategic Plan for fiscal year (FY) 2010–2015 targets the restoration of watershed and forest health as a core management objective of the national forests and grasslands. To achieve this goal, the Forest Service, an agency of USDA, is directed to restore degraded watersheds by strategically focusing investments in watershed improvement projects and conservation practices at landscape and watershed scales. The Forest Service formed the National Watershed Condition Team and tasked it with developing a nationally consistent, science-based approach to classify the condition of all National Forest System (NFS) watersheds and to develop outcome-based performance measures for watershed restoration. The team evaluated alternative approaches for classifying watersheds (USDA Forest Service 2007) and developed the watershed condition classification (WCC) system described in this technical guide. The team designed the WCC system to—Classify the condition of all NFS watersheds; Be quantitative to the extent feasible; Rely on Geographic Information System (GIS) technology; Be cost effective; Be implementable within existing budgets; Include resource areas and activities that have a significant influence on watershed condition. National forests are required to revise the classification on an annual basis. The WCC system is a national forest-based, reconnaissance level evaluation of watershed condition achievable within existing budgets and staffing levels that can be aggregated for a national assessment of watershed condition. The WCC system offers a systematic, flexible means of classifying watersheds based on a core set of national watershed condition indicators. The system relies on professional judgment exercised by forest interdisciplinary (ID) teams, GIS data, and national databases to the extent they are available, and on written rule sets and criteria for indicators that describe the three watershed condition classes (functioning properly, functioning at risk, and impaired function). The WCC system relies on Washington Office and regional office oversight for flexible and consistent application among national forests. The WCC system is a first approximation of watershed condition, and we will revise and refine it over time. The expectation is that we will improve and refine individual resource indicators and that we will develop databases and map products to assist with future classifications. The WCC information will be incorporated into the watershed condition framework, which will ultimately be employed to establish priorities, evaluate program performance, and communicate watershed restoration successes to interested stakeholders and Congress. The watershed condition goal of the Forest Service is “to protect National Forest System watersheds by implementing practices designed to maintain or improve watershed condition, which is the foundation for sustaining ecosystems and the production of renewable natural resources, values, and benefits” (FSM 2520). U.S. Secretary of Agriculture Tom Vilsack reemphasized this policy in his “Vision for the Forest Service” when he stated that achieving restoration of watershed and forest health would be the primary management objective of the Forest Service (USDA 2010). This Watershed Condition Classification Technical Guide helps to implement this policy objective by—1. Establishing a systematic process for determining watershed condition class that all national forests can apply consistently; 2. Improving Forest Service reporting and tracking of watershed condition; 3. Strengthening the effectiveness of the Forest Service to maintain and restore the productivity and resilience of watersheds and their associated aquatic systems on NFS lands.

Download or read book The Great Quake written by Henry Fountain and published by Crown Publishing Group (NY). This book was released on 2017 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: On March 27, 1964, at 5-36 p.m., the biggest earthquake ever recorded in North America--and the second biggest ever in the world, measuring 9.2 on the Richter scale--struck Alaska, devastating coastal towns and villages and killing more than 130 people in what was then a relatively sparsely populated region. In a riveting tale about the almost unimaginable brute force of nature, New York Times science journalist Henry Fountain, in his first trade book, re-creates the lives of the villagers and townspeople living in Chenega, Anchorage, and Valdez; describes the sheer beauty of the geology of the region, with its towering peaks and 20-mile-long glaciers; and reveals the impact of the quake on the towns, the buildings, and the lives of the inhabitants. George Plafker, a geologist for the U.S. Geological Survey with years of experience scouring the Alaskan wilderness, is asked to investigate the Prince William Sound region in the aftermath of the quake, to better understand its origins. His work confirmed the then controversial theory of plate tectonics that explained how and why such deadly quakes occur, and how we can plan for the next one.

Download or read book Machine Learning for Ecology and Sustainable Natural Resource Management written by Grant Humphries and published by Springer. This book was released on 2018-11-05 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists and natural resource managers are charged with making complex management decisions in the face of a rapidly changing environment resulting from climate change, energy development, urban sprawl, invasive species and globalization. Advances in Geographic Information System (GIS) technology, digitization, online data availability, historic legacy datasets, remote sensors and the ability to collect data on animal movements via satellite and GPS have given rise to large, highly complex datasets. These datasets could be utilized for making critical management decisions, but are often “messy” and difficult to interpret. Basic artificial intelligence algorithms (i.e., machine learning) are powerful tools that are shaping the world and must be taken advantage of in the life sciences. In ecology, machine learning algorithms are critical to helping resource managers synthesize information to better understand complex ecological systems. Machine Learning has a wide variety of powerful applications, with three general uses that are of particular interest to ecologists: (1) data exploration to gain system knowledge and generate new hypotheses, (2) predicting ecological patterns in space and time, and (3) pattern recognition for ecological sampling. Machine learning can be used to make predictive assessments even when relationships between variables are poorly understood. When traditional techniques fail to capture the relationship between variables, effective use of machine learning can unearth and capture previously unattainable insights into an ecosystem's complexity. Currently, many ecologists do not utilize machine learning as a part of the scientific process. This volume highlights how machine learning techniques can complement the traditional methodologies currently applied in this field.
Download or read book Encyclopedia of the World s Endangered Languages written by Christopher Moseley and published by Routledge. This book was released on 2008-03-10 with total page 946 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concern for the fast-disappearing language stocks of the world has arisen particularly in the past decade, as a result of the impact of globalization. This book appears as an answer to a felt need: to catalogue and describe those languages, making up the vast majority of the world's six thousand or more distinct tongues, which are in danger of disappearing within the next few decades. Endangerment is a complex issue, and the reasons why so many of the world's smaller, less empowered languages are not being passed on to future generations today are discussed in the book's introduction. The introduction is followed by regional sections, each authored by a notable specialist, combining to provide a comprehensive listing of every language which, by the criteria of endangerment set out in the introduction, is likely to disappear within the next few decades. These languages make up ninety per cent of the world's remaining language stocks. Each regional section comprises an introduction that deals with problems of language preservation peculiar to the area, surveys of known extinct languages, and problems of classification. The introduction is followed by a list of all known languages within the region, endangered or not, arranged by genetic affiliation, with endangered and extinct languages marked. This listing is followed by entries in alphabetical order covering each language listed as endangered. Useful maps are provided to pinpoint the more complex clusters of smaller languages in every region of the world. The Encyclopedia therefore provides in a single resource: expert analysis of the current language policy situation in every multilingual country and on every continent, detailed descriptions of little-known languages from all over the world, and clear alphabetical entries, region by region, of all the world's languages currently thought to be in danger of extinction. The Encyclopedia of the World’s Endangered Languages will be a necessary addition to all academic linguistics collections and will be a useful resource for a range of readers with an interest in development studies, cultural heritage and international affairs.
