Seed Conservation

"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.

Faced with widespread and devastating loss of biodiversity in wild habitats, scientists have developed innovative strategies for studying and protecting targeted plant and animal species in "off-site" facilities such as botanic gardens and zoos. Such ex situ work is an increasingly important component of conservation and restoration efforts. Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr., Kayri Havens, and Mike Maunder, is the first book to address integrated plant conservation strategies and to examine the scientific, technical, and strategic bases of the ex situ approach. The book examines where and how ex situ investment can best support in situ conservation. Ex Situ Plant Conservation outlines the role, value, and limits of ex situ conservation as well as updating best management practices for the field, and is an invaluable resource for plant conservation practitioners at botanic gardens, zoos, and other conservation organizations; students and faculty in conservation biology and related fields; managers of protected areas and other public and private lands; and policymakers and members of the international community concerned with species conservation.

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.

Across the United States, millions of acres of land have been so disturbed by human activities or severe climate events that significant portions of their native plant communities have been lost and their ecosystems have been seriously compromised. Restoring impaired ecosystems requires a supply of diverse native plant seeds that are well suited to the climates, soils, and other living species of the system. Native seeds are also in demand for applications in urban land management, roadside maintenance, conservation agriculture, and other restorative activities that take into account the connection between native plant communities and the increasingly urgent need for resilient landscapes. Given the varied climatic and environmental niches of the more than 17,000 native plant species of the United States, supplying the desired seed types and species mixes for this wide range of activities is a challenge. As the first phase of a nationwide analysis of the full scope of needs for native plant seeds, this interim report describes the participants in the native plant seed supply chain, makes preliminary observations, and proposes an information-gathering plan for the second phase of the assessment.

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.

Community seed banks first appeared towards the end of the 1980s, established with the support of international and national non-governmental organizations. This book is the first to provide a global review of their development and includes a wide range of case studies. Countries that pioneered various types of community seed banks include Bangladesh, Brazil, Ethiopia, India, Nepal, Nicaragua, the Philippines and Zimbabwe. In the North, a particular type of community seed bank emerged known as a seed-savers network. Such networks were first established in Australia, Canada, the UK and the USA before spreading to other countries. Over time, the number and diversity of seed banks has grown. In Nepal, for example, there are now more than 100 self-described community seed banks whose functions range from pure conservation to commercial seed production. In Brazil, community seed banks operate in various regions of the country. Surprisingly, despite 25 years of history and the rapid growth in number, organizational diversity and geographical coverage of community seed banks, recognition of their roles and contributions has remained scanty. The book reviews their history, evolution, experiences, successes and failures (and reasons why), challenges and prospects. It fills a significant gap in the literature on agricultural biodiversity and conservation, and their contribution to food sovereignty and security.
