Natural Conclusions from the Rockies by David F. Baker Pdf
Rocky Mountain bighorn sheep forage in vegetation they can see over, and they keep to high visibility areas with clear escape routes and topographic relief that enables them to see long distances. Their excellent vision makes them an appropriate role model for Christian living. Christians need to live with eternitys values in view. Were instructed to set our mind on things above. We need to stand where we can look over the top of earthly things to see heavenly things. We need to climb up to those high visibility places where we can see forever. Fifty awesome natural facts Fifty corresponding character-building natural conclusions Natural history background material with scientific definitions Personal illustrations for children and youth Reinforcing projects and activities Bible study section for instructors Adult application sections
The Rockies are familiar to everyone in North America, yet few appreciate the true diversity of these mountains. This book covers the Rockies from sagebrush flats to icy tundra, and explores the range’s geological formation; its role in shaping the West; the plants and animals that form its many ecosystems; and the complex relationship between humans and the Rockies. Written in a lively, engaging style, the book features spectacular color photographs, elegant line drawings, and interesting sidebars.
Natural Regeneration of Engelmann Spruce After Clearcutting in the Central Rocky Mountains in Relation to Environmental Factors by Robert R. Alexander Pdf
The Rocky Mountain West is largely arid and steep, with ecological scars from past human use visible for hundreds of years. Just how damaging were the past 150 years of activity? How do current rates of disturbance compare with past mining, grazing, and water diversion activities? In the face of constant change, what constitutes a "natural" ecosystem? And can a high quality of life be achieved for both human and natural communities in this region. Rocky Mountain Futures presents a comprehensive and wide-ranging examination of the ecological consequences of past, current, and future human activities in the Rocky Mountain region of the United States and Canada. The book brings together 32 leading ecologists, geographers, and other scientists and researchers to present an objective assessment of the cumulative effects of human activity on the region's ecological health and to consider changes wrought by past human use. This combined view of past and present reveals where Rocky Mountain ecosystems are heading, and the authors project what the future holds based upon current economic and social trends and the patterns that emerge from them. The book: examines the biogeographic and paleoenvironmental setting and historical climate that have shaped Rocky Mountain ecosystems traces the direct human influences on landscapes and ecosystems over the past 150 years explores the cumulative effects of past, present, and projected future human activities on tundra, subalpine and montane forests, valleys, grasslands, and waters offers case studies that illustrate specific examples of human influence and current efforts to restore the environment Case studies focus on northern New Mexico; Summit County, Colorado; Flathead Valley, Montana; and Alberta, Canada. Among the contributors are Craig D. Allen, N. Thompson Hobbs, Linda L. Joyce, Robert E. Keane, David Schindler, Timothy R. Seastedt, David Theobald, Diana Tomback, William Travis, Cathy Whitlock, and Jack Stanford. The United Nations has proclaimed 2002 as the International Year of Mountains to increase international awareness of the global importance of mountain ecosystems. The case-based multidisciplinary approach of this book constitutes an important new model for understanding the implications of land-use practices and economic activity on mountains, and will serve a vital role in improving decisionmaking both in the Rocky Mountains and in other parts of the world that face similar challenges.

Fire, Native Peoples, and the Natural Landscape by Thomas Vale Pdf
For nearly two centuries, the creation myth for the United States imagined European settlers arriving on the shores of a vast, uncharted wilderness. Over the last two decades, however, a contrary vision has emerged, one which sees the country's roots not in a state of "pristine" nature but rather in a "human-modified landscape" over which native peoples exerted vast control. Fire, Native Peoples, and the Natural Landscape seeks a middle ground between those conflicting paradigms, offering a critical, research-based assessment of the role of Native Americans in modifying the landscapes of pre-European America. Contributors focus on the western United States and look at the question of fire regimes, the single human impact which could have altered the environment at a broad, landscape scale, and which could have been important in almost any part of the West. Each of the seven chapters is written by a different author about a different subregion of the West, evaluating the question of whether the fire regimes extant at the time of European contact were the product of natural factors or whether ignitions by Native Americans fundamentally changed those regimes. An introductory essay offers context for the regional chapters, and a concluding section compares results from the various regions and highlights patterns both common to the West as a whole and distinctive for various parts of the western states. The final section also relates the findings to policy questions concerning the management of natural areas, particularly on federal lands, and of the "naturalness" of the pre-European western landscape.
Manufacturing National Park Nature by J. Keri Cronin Pdf
National parks occupy a prominent place in the Canadian imagination, yet we are only beginning to understand how their visual representation has shaped and continues to inform our perceptions of ecological issues and the natural world. J. Keri Cronin draws on historical and modern postcards, advertisements, and other images of Jasper National Park to trace how various groups and the tourism industry have used photography to divorce the park from real environmental threats and instead package it as a series of breathtaking vistas and adorable-looking animals. Manufacturing National Park Nature demonstrates that popular forms of picturing nature can have ecological implications that extend far beyond the frame of the image.
The Memory of Nature in Aboriginal, Canadian and American Contexts by Françoise Besson,Claire Omhovère,Héliane Ventura Pdf
This volume engages the reader’s interest in the relationship that binds man to nature, a relationship which makes itself manifest through certain literary or visual artefacts produced by Native or non-Native writers and artists. It ranges from the study of literatures (mainly from Canada – including Quebec and Acadia – but also from Britain, the United States of America, France, Turkey, and Australia) to the exploration of films, photographs, paintings and sculptures produced by Aboriginal artists from North America. Thanks to a relational paradigm founded on spatial and temporal enlargement, it re-imagines the critical outlook on indigenous production by instigating a dialogue between endogenous and exogenous scholars, novelists and artists, and by weaving together interdisciplinary approaches spanning anthropology, geology, ecocriticism and the study of myths. From the writings by Scott Momaday to those by Tomson Highway, from Pauline Johnson to Louise Erdrich, or from the photographs by William McFarlane Notman and Edward Burtynsky or the films by Randy Redroad to the paintings by Emily Carr, it explores art as the sedimentation of nature. It simultaneously interrogates the representation of nature and the nature of representation as a geological and generic process inscribed in the history of mankind. Without eclipsing differences and imposing a reified Eurocentric critical discourse upon indigenous productions, this volume does not colonize indigenous texts or indulge in cultural appropriation of works of art, but looks for historical, mythological or geological traces of the past; a past characterized by the intimacy between man and animal, man and rock, or man and plant, a past which is allowed to resurface through the creative and critical outlooks that are bestowed upon its subjacent or subterranean existence. It resurfaces, not as nostalgic memory but as an interactive fertilization giving the present a new life in which the non-human provides a key to the understanding of the human bond to nature.
Much has been written about the girl sleuth in fiction, a feminist figure embodying all the potential wit and drive of girlhood. Her male counterpart, however, has received much less critical attention despite his popularity in the wider culture. This collection of 11 essays examines the boy detective and his genre from a number of critical perspectives, addressing the issues of these young characters, heirs to the patriarchy yet still concerned with first crushes and soda shop romances. Series explored include the Hardy Boys, Tow Swift, the Three Investigators, Christopher Cool and Tim Murphy, as well as works by Astrid Lindgren, Mark Haddon and Joe Meno.

The Economics of Natural Environments by John V. Krutilla,Anthony C. Fisher Pdf
In this pioneering study, Krutilla and Fisher put the amenity resources of natural environments into an analytical framework comparable to that for the extractive resources. The models and theoretical background of their techniques are illustrated by case studies which include the controversial Hells Canyon dam, the Mineral King ski resort, and the Trans-Alaska pipeline. The authors point out that resource development activities undertaken on public lands often receive financial advantages---preferential tax treatment, subsidized capital, and access to public resources---that are not taken into account in the costs of the project. True evaluation of the costs and benefits of a development project often tips the balance in favor of preserving an area in a natural state.

The Early Writings of Harold W. Clark and Frank Lewis Marsh by Ronald L. Numbers Pdf
Originally published in 1995, The Early Writings of Harold W. Clark and Frank Lewis Marsh is the eighth volume in the Creationism in Twentieth Century America series, reissued in 2019. The book is a collection of original writings by the prominent creationist Harold W. Clark, and the biologist, educator and young Earth creationist Frank Lewis Marsh. Although both were significant figures in the anti-evolutionist movement of the early 20th century, unlike other members of the movement, both Marsh and Clarke were trained scientists studying under eminent evolutionists of the time. Both writers struggled to reconcile new scientific understandings of geology, botany and palaeontology, supported by Darwin’s theory of evolution, with their own creationist beliefs in genesis and flood theory. Both scientists as such began to develop their own theories of evolution that remained in line with creationist beliefs. This compact and unique collection includes the writings of Marsh and Clark from this period, featuring some of their well-known works on the subject including ‘Back to Creation’ and ‘Fundamental Biology’. This volume of original sources will be of interest to academics of religion, natural history and historians of the 19th century.
Southern Rockies Wildlands Network Vision by Southern Rockies Ecosystem Project,Wildlands Project,Denver Zoo Pdf
World-renowned for their striking beauty and high mountain topography, the Southern Rockies are one of North America's gems. The Southern Rockies Ecoregion contains a diversity of life. From alpine tundra to ponderosa pine forests and sagebrush grasslands, over 500 vertebrate species find their home in the Southern Rockies as well as a rich variety of plants and invertebrates including over 270 species of butterflies and 5,200 species of moths. It is able to obtain this abundance partially because of its continuous stretches of wild, remote and undeveloped lands. And yet, this biodiversity is threatened, as are many wild places in North America, due to human expansion and development: native species have been extirpated; old growth forests logged, wild and powerful rivers dammed and polluted, and land degraded. The Southern Rockies Wildlands Network Vision calls for ecological restoration that is based on healing these ecological wounds: the Vision identifies these wounds to the land and then considers anthropogenic causes for each, addressing not only the symptoms and the disease, but also the root cause(s) of the illness. The injuries to the Southern Rockies that have been identified by the Vision include: * Loss and Decline of Native Species * Loss and Degradation of Terrestrial and Aquatic Ecosystems * Loss and Alteration of Natural Processes * Fragmentation of Wildlife Habitat * Invasion of Exotic Species * Pollution and Climate Change The current state of the Southern Rockies indicates that conservation planning and work is imperative. This Vision is a comprehensive look into that work, which is based in rewilding. It provides six goals and tangible implantation tactics relating to those goals in order to make the Vision a reality. These goals include protecting and recovering native species and their habitats, reducing pollution, controlling and removing exotic species, maintaining ecological and evolutionary processes and restoring landscape connectivity. The Vision is a prescription for the future. It recognizes that national parks, wilderness areas, and wildlife refuges have accomplished a great deal for nature. But over time, protected areas have been surrounded by roads and degraded landscapes. Now, the protected areas are too isolated to sustain viable populations of large animals, let alone many ecological and evolutionary processes. The Southern Rockies Wildlands Network Vision is a conservation blueprint and collaborative effort of the Southern Rockies Ecosystem Project, the Denver Zoo, and the Wildlands Project for the Southern Rockies of Colorado, Wyoming and New Mexico.
