"This book is a review of the current scientific knowledge that underpins seed banking, a technology which plays a key role in the conservation of both domesticated and non-domesticated plant speices..."--Publisher description.
As biological diversity continues to shrink at an alarming rate, the loss of plant species poses a threat seemingly less visible than the loss of animals but in many ways more critical. In this book, one of America's leading ethnobotanists warns about our loss of natural vegetation and plant diversity while providing insights into traditional Native agricultural practices in the Americas. Gary Paul Nabhan here reveals the rich diversity of plants found in tropical forests and their contribution to modern crops, then tells how this diversity is being lost to agriculture and lumbering. He then relates "local parables" of Native American agriculture—from wild rice in the Great Lakes region to wild gourds in Florida—that convey the urgency of this situation and demonstrate the need for saving the seeds of endangered plants. Nabhan stresses the need for maintaining a wide gene pool, not only for the survival of these species but also for the preservation of genetic strains that can help scientists breed more resilient varieties of other plants. Enduring Seeds is a book that no one concerned with our environment can afford to ignore. It clearly shows us that, as agribusiness increasingly limits the food on our table, a richer harvest can be had by preserving ancient ways. This edition features a new foreword by Miguel Altieri, one of today's leading spokesmen for sustainable agriculture and the preservation of indigenous farming methods.
Farmers and gardeners have long appreciated a wide variety of plants and have nurtured them for meals, healing, and exchange. But diversity too often has been surrendered to monocultures of fields and spirits, predisposing much of modern agriculture to uniformity and, consequently, vulnerability. Today it is primarily at the individual level—such as growing and saving a strange old bean variety or a curious-looking gourd—that any lasting conservation actually takes place. As scientists grapple with the erosion of genetic diversity of crops and their wild relatives, old-timey farmers and gardeners continue to save, propagate, and pass on folk varieties and heirloom seeds. Virginia Nazarea focuses on the role of these seedsavers in the perpetuation of diversity. She thoughtfully examines the framework of scientific conservation and argues for the merits of everyday conservation—one that is beyond programmatic design. Whether considering small-scale rice and sweet potato farmers in the Philippines or participants in the Southern Seed Legacy and Introduced Germplasm from Vietnam in the American South, she explores roads not necessarily less traveled but certainly less recognized in the conservation of biodiversity. Through characters and stories that offer a wealth of insights about human nature and society, Heirloom Seeds and Their Keepers helps readers more fully understand why biodiversity persists when there are so many pressures for it not to. The key, Nazarea explains, is in the sovereign spaces seedsavers inhabit and create, where memories counter a culture of forgetting and abandonment engendered by modernity. A book about theory as much as practice, it profiles these individuals, who march to their own beat in a world where diversity is increasingly devalued as the predictability of mass production becomes the norm. Heirloom Seeds and Their Keepers offers a much-needed, scientifically researched perspective on the contribution of seedsaving that illustrates its critical significance to the preservation of both cultural knowledge and crop diversity around the world. It opens new conversations between anthropology and biology, and between researchers and practitioners, as it honors conservation as a way of life.
“Empire forestry”—the broadly shared forest management practice that emerged in the West in the nineteenth century—may have originated in Europe, but it would eventually reshape the landscapes of colonies around the world. Melding the approaches of environmental history and political ecology, Colonial Seeds in African Soil unravels the complex ways this dynamic played out in twentieth-century colonial Sierra Leone. While giving careful attention to topics such as forest reservation and exploitation, the volume moves beyond conservation practices and discourses, attending to the overlapping social, economic, and political contexts that have shaped approaches to forest management over time.
A pamphlet describing the contents of the CIMMYT germplasm bank, the conditions of their storage and management, and how to obtain germplasm from the bank.
This publication provides an approach by which conservationists can determine whether or not long-term seed storage is feasible for a particular species, i.e. whether or not that species shows orthodox seed storage behaviour, and provides advice on the implementation of the protocol, examples of ways in which the results from seed storage studies could be misinterpreted due to confounding factors, as well as several alternative approaches for estimating seed storage behaviour prior to carryng out actual investigations with the seeds. In particular, the latter section introduces the concept of a multicriteria approach for estimating seed storage behaviour.

Maintain viability with these techniques for proper seed storage!Healthy, viable seeds are the foundation for sustainable crop production, while poorly kept seeds can result in low germination and crop loss. Seed Storage of Horticultural Crops suggests appropriate strategies to help farmers and breeders store seeds of all kinds.
Substantial progress has been made in seed science during the past few years, emphasizing the important role seed biology plays in advancing plant biotechnology, agriculture and plant resource management and conservation. This book describes the status of seed research and technology.
Approaching the contributions of a world-wide sector of scientific institutions to addressing the extinction crisis, Botanical Gardens and Their Role in Plant Conservation brings together a diversity of perspectives. There are more than 3,600 botanical gardens worldwide, where trees, shrubs, herbs, and other plants are studied and managed in collections. They are foremost among efforts to conserve the diversity of living plant species and ensure that crucial biodiversity is available for the future of humanity. This book is a showcase for plant conservation, restoration, biodiversity, and related scientific and educational work of botanical gardens around the world, featuring both thematic overview chapters and numerous case studies that illustrate the critical role these institutions play in fighting extinction and ensuring plant diversity is available for sustainable use. FEATURES A wide range of case studies derived from practical experience in a diversity of institutional, national, and biogeographical settings, Reviews of topics such as networking amongst institutions, the importance of global policy agreements such as the Convention on Biological Diversity and the Global Strategy for Plant Conservation, Profiles of botanical gardens contributions at the national level to conservation priorities, Real-world examples of programs in plant conservation for both critically endangered wild plant diversity and unique horticultural or cultural germplasm. Botanical Gardens and Their Role in Plant Conservation includes contributions from institutions from Africa, Asia, Australia, Europe, and the Americas, and institutions of all sizes and histories, from long-established national gardens to new gardens offering their perspectives on developing their roles in this vital undertaking.
