Conservation Biology
• • • John Harper • • • Nature conservation has changed from an idealistic philosophy to a serious technology. Ecology, the science that underpins the technol ogy of conservation, is still too immature to provide all the wisdom that it must. It is arguable that the desire to conserve nature will in itself force the discipline of ecology to identify fundamental prob lems in its scientific goals and methods. In return, ecologists may be able to offer some insights that make conservation more practicable (Harper 1987). The idea that nature (species or communities) is worth preserv ing rests on several fundamental arguments, particularly the argu ment of nostalgia and the argument of human benefit and need. Nostalgia, of course, is a powerful emotion. With some notable ex ceptions, there is usually a feeling of dismay at a change in the sta tus quo, whether it be the loss of a place in the country for walking or rambling, the loss of a painting or architectural monument, or that one will never again have the chance to see a particular species of bird or plant.
Introduction to California Plant Life
California's remarkably diverse plants range in size from the stately coast redwoods to the minute belly plants of the southern deserts. This is the only concise overview of the state's unique flora, its plant communities, and the environmental factors that shape them. 156 illustrations.
Federal Ecosystem Management
For the better part of the last century, "preservation" and "multi-use conservation" were the watchwords for managing federal lands and resources. But in the 1990s, amidst notable failures and overwhelming needs, policymakers, land managers, and environmental scholars were calling for a new paradigm: ecosystem management. Such an approach would integrate federal land and resource management across jurisdictional boundaries; it would protect biodiversity and economic development; and it would make federal management more collaborative and less hierarchical. That, at any rate, was the idea. Where the idea came from—why ecosystem management emerged as official policy in the 1990s—is half of...
Theological Foundations for Environmental Ethics
This book asks whether religion can make a positive contribution to preventing further destruction of biological diversity and ecosystems and threats to our earth. The author reconstructs the teachings of Augustine, Thomas Aquinas and other classic thinkers to reflect our current scientific understanding of the world.
Transpecies Design
In May 2019, the United Nations released the Global Assessment Report on Biodiversity and Ecosystem Services which warned that human activities will drive nearly one million species to extinction in a few decades. The primary reasons for this are habitat loss and biodiversity demise caused by changing climate, pollution, introducing nonindigenous species, clearing land, over population, and consumption. Given this situation, humans must change course as both human wellbeing and the wellbeing of other-than-human species are imbricated in one another. One way humanity can accomplish the needed transformation is to move beyond an anthropocentric view of life by embracing a transpecies approach ...

The Ecological Basis of Conservation
From its inception, the U.S. Department of the Interior has been charged with a conflicting mission. One set of statutes demands that the department must develop America's lands, that it get our trees, water, oil, and minerals out into the marketplace. Yet an opposing set of laws orders us to conserve these same resources, to preserve them for the long term and to consider the noncommodity values of our public landscape. That dichotomy, between rapid exploitation and long-term protection, demands what I see as the most significant policy departure of my tenure in office: the use of science-interdisciplinary science-as the primary basis for land management decisions. For more than a century, ...
