This book was released on 2018-03-17 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Number of Plots Required for Measuring Productivity on Mountain Grasslands in Montana The purpose of this Research Note is to show the relationship between sample size (number of plots) and precision of measuring production on 12 mountain grassland and shrubland habitat types2 common to western Montana. This information should help the range manager obtain a more realistic view of the validity of his production determinations on these and similar habitat-types, i. Information presented in table 1 was developed from data obtained during a study to determine forage productivity and variability on important habitat types. Ten of the 12 habitat types are represented by three stands selected to span the range in productivity potential for the respective habitat type; the remaining two habitat types are represented by only two stands in each. A sampling technique combining estimation (40 plots) and clipping (10 plots) was used to determine production. The 10 clipped - ft2 circular plots were randomly distributed within each stand. These clipped plots provided an estimate of the coefficient of variation (cv) by vegetation classes and species in each stand. The CV in turn forms the basis for determining the number of plots required to achieve given levels of sampling precision. The formula used to compute the number of plots (n) needed for the specified levels of sampling accuracy (freese 1967) shown in table 1 is.

This book was released on 2018-09-10 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Plant Development and Yield on Mountain Grasslands in Southwestern Montana Annual differences in plant growth and production are among the most commonly observed phenomena on our native rangelands. In addition, knowledge of growth and production are fundamental to understanding the dynamics of the grassland ecosystem. Despite their conspicuousness and importance, these phenomena have not been documented for all range types. Mountain grasslands of western Montana are among those areas where information is generally lacking on yearly variations in plant development and herbage yield.

Download or read book High Mountain Conservation in a Changing World written by Jordi Catalan and published by Springer. This book was released on 2017-08-03 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.
Download or read book This Land written by Christopher Ketcham and published by . This book was released on 2019 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The public lands of the western United States comprise some 450 million acres of grassland, steppe land, canyons, forests, and mountains. It's an American commons, and it is under assault as never before. Journalist Christopher Ketcham has been documenting the confluence of commercial exploitation and governmental misconduct in this region for over a decade. His revelatory book takes the reader on a journey across these last wild places, to see how capitalism is killing our great commons. Ketcham begins in Utah, revealing the environmental destruction caused by unregulated public lands livestock grazing, and exposing rampant malfeasance in the federal land management agencies, who have been compromised by the profit-driven livestock and energy interests they are supposed to regulate. He then turns to the broad effects of those corrupt politics on wildlife. He tracks the Department of Interior's failure to implement and enforce the Endangered Species Act--including its stark betrayal of protections for the grizzly bear and the sage grouse--and investigates the destructive behavior of U.S. Wildlife Services in their shocking mass slaughter of animals that threaten the livestock industry. Along the way, Ketcham talks with ecologists, biologists, botanists, former government employees, whistleblowers, grassroots environmentalists and other citizens who are fighting to protect the public domain for future generations. This Land is a colorful muckraking journey--part Edward Abbey, part Upton Sinclair--exposing the rot in American politics that is rapidly leading to the sell-out of our national heritage"--
