By studying fish in streams and by closely observing the natural water cycle, Viktor Schauberger (1885-1958) was able to solve basic problems of energy transformation. He saw that modern man, without realizing it, was destroying the earth and sabotaging his own cultures by working against Nature. All the prevailing methods of energy generation - from hydro-electric to nuclear fission - produce harmful long-term effects on the environment and encourage disease. Schauberger had a clear vision of how fertility could be restored to the earth. As an inventor Schauberger developed a number of ingenious machines which would revolutionize farming, horticulture, forestry and aircraft propulsion. He developed water purification systems, and showed how air and water could be harnessed as fuels for many machines. His discovery of implosive energy and diamagnetism had many practical applications, most of which have yet to be developed.

    Originally published and presented to Congress last fall, this book serves as a valuable introduction to the current crisis America faces.

    This personal narrative is thoroughly documented and includes maps and scores of rare, old photographs.

    It is divided into four forms of classification: drawings of 'perfect' tracks matched with photographs of the same tracks in sand or mud; color illustrations depicting scats of 128 species of mammals--with a distribution maps and habitat information--along with pellets and scats of birds, reptiles and invertebrates; detailed descriptions and over 70 color photographs of the distinctive traces of mammals at shelters and feeding sites; and 40 full page plates of skulls, lower jaws, humeri and femurs covering the more commonly found species, plus a detailed guide covering all mammal groups. Naturalists are becoming increasingly aware of the value of the indirect methods of finding and identifying mammals. This handbook of detection will be an essential companion to be kept in the pocket, backpack or car for constant ready reference.

    Instructions for identifying 40 species of ducks, geese and swans.

    Almost all ecological and conservation work involves carrying out a census or survey. This practically focussed book describes how to plan a census, the practical details and shows with worked examples how to analyse the results. The first three chapters describe planning, sampling and the basic theory necessary for carrying out a census. In the subsequent chapters international experts describe the appropriate methods for counting plants, insects, fish, amphibians, reptiles, mammals and birds. As many censuses also relate the results to environmental variability, there is a chapter explaining the main methods. Finally, there is a list of the most common mistakes encountered when carrying out a census.

    

    An insider's critique of endangered-species policy in action, Prairie Night combines an understanding of the biology and natural history of North America's most endangered mammal with a record of the often controversial decisions on how to save it.

    This reflects a realization of the importance of heritage as a major industry, particularly in tourism, as well as the essential support it gives to cultural and social identities. This study attempts to identify and examine the heritage industry, offering a better understanding of the nature of heritage, its various uses and important economic, social, cultural and political impacts.

    Nerburn's essays range broadly from deeply personal narratives of the author's experiences among the Ojibwe, to dark meditations on the uncompromising winters of northern Minnesota, to mystical celebrations of water and light. Throughout, Nerburn writes with an incandescent radiance and intellectual passion that are at once elemental, provocative, and startling. Deeply grounded in the struggle for authentic spiritual awakening - a path based on awareness rather than explanation - Nerburn's words illuminate the intricate subtleties of nature with intimacy and power.
