Aerial Photography for Assessment of Black-tailed Prairie Dog Management on the Buffalo Gap National Grassland, South Dakota
Author: Conservation of the Black-Tailed Prairie Dog
Author: John HooglandPublisher: Island Press
ISBN: 1597268526

Pages : 368
Book Description
The prairie dog is a colonial, keystone species of the grassland ecosystem of western North America. Myriad animals regularly visit colony-sites to feed on the grass there, to use the burrows for shelter or nesting, or to prey on the prairie dogs. Unfortunately, prairie dogs are disappearing, and the current number is only about 2% of the number encountered by Lewis and Clark in the early 1800s. Part I of Conservation of the Black-Tailed Prairie Dog summarizes ecology and social behavior for pivotal issues such as when prairie dogs breed, how far they disperse, how they affect other organisms, and how much they compete with livestock. Part II documents how loss of habitat, poisoning, plague, and recreational shooting have caused the precipitous decline of prairie dog populations over the last 200 years. Part III proposes practical solutions that can ensure the long-term survival of the prairie dog and its grassland ecosystem, and also are fair to private landowners. We cannot expect farmers and ranchers to bear all the costs of conservation while the rest of us enjoy all the benefits. With 700 references, 37 tables, 75 figures and photographs, and a glossary, Conservation of the Black-Tailed Prairie Dog is a unique and vital contribution for wildlife managers, politicians, environmentalists, and curious naturalists.

Category : Photography
Languages : en
Pages : 216
Book Description
The Aerial Photo Sourcebook is an illustrated reference for the novice. It has a complete bibliography of over 800 books and articles for those looking for more details on aerial photography. Collins provides the most comprehensive listing available of federal government sources, state and regional sources, and commercial sources and collections. All contact information (names, offices, addresses, phone, and fax) is included. The sourcebook begins with an overview of the field and with basic instruction in photographic interpretation. The fundamentals section explores the variety of aerial photography: color infrared, black and white, and color. It also explains the difference between oblique and vertical views. Collins discusses formats, tools, and map skills in clear, non-technical terms. She summarizes the traditional roles of aerial photography, as well as the new customers that aerial photography will serve in the future. A bibliography of more than 800 items from over 40 subject areas is included. The bibliography consists primarily of English or English-translated works related to aerial photography in the United States, augmented by a few international perspectives are included.The bibliography lists information and research in aerial photography in the fields of agriculture, balloon and kite photography, geology, history, intelligence, mapping and cartography, aerial photo interpretation, remote sensing, transportation, soil studies, urban problems, wetlands, and more. The Aerial Photo Sourcebook offers numerous ideas for using aerial photography to solve a wide range of problems, to enhance presentations, and to facilitate research.

Spatial Optimization in Ecological Applications
Author: John G. HofPublisher: Columbia University Press
ISBN: 0231125453
Category : Nature
Languages : en
Pages : 287
Book Description
Whether discussing habitat placement for the northern spotted owl or black-tailed prairie dog or strategies for controlling exotic pests, this book explains how capturing ecological relationships across a landscape with pragmatic optimization models can be applied to real world problems. Using linear programming, Hof and Bevers show how it is possible for the researcher to include many thousands of choice variables and many thousands of constraints and still be quite confident of being able to solve the problem in hand with widely available software. The authors' emphasis is to preserve optimality and explore how much ecosystem function can be captured, stressing the solvability of large problems such as those in real world case studies.
