Crop wild relatives (CWR) are species closely related to crop plants which can contribute beneficial traits, such as pest or disease resistance and yield improvement. These species are critical for improving agricultural production and increasing food security. They are also essential components of natural and semi-natural habitats as well as agricultural systems, and are therefore vital in maintaining ecosystem health. However, CWR, like any other group of wild species, are subject to an increasing range of threats: habitat loss, degradation and mismanagement, over-collection and climate change. Through an examination of the national, regional and global context of CWR, these authoritative studies present methodologies and case studies that review and provide recommendations for global conservation and use. Topics range from the establishment of conservation priorities and strategies, threat assessment and genetic erosion and pollution.

Conservation in protected areas has focused on preserving biodiversity of ecosystems and species, whereas conserving the genetic diversity contained within species has historically often been ignored. However, maintaining genetic diversity is fundamental to food security and the provision of raw materials and it is best preserved within plants' natural habitats. This is particularly true for wild plants that are directly related to crop species and can play a key role in providing beneficial traits, such as pest or disease resistance and yield improvement. These wild relatives are presently threatened due to processes of habitat destruction and change and methodologies have been adapted to provide in-situ conservation through the establishment of genetic reserves within the existing network of protected areas. Providing a long-awaited synthesis of these new methodologies, this book presents a practical set of management guidelines that can be used for the conservation of plant genetic diversity of crop wild relatives in protected areas.
