Book Description
Crop wild relatives (CWR) are plant species which are more or less closely related to crops. They are a vital resource by providing a pool of genetic variation that can be used in breeding new and better adapted varieties of crops that are resistant to stress, disease, drought and other factors. They will be increasingly important in allowing crops to adapt to the impacts of climate, thus safeguarding future agricultural production. Until recently, the main conservation strategy adopted for CWR has been ex situ - through the maintenance of samples as seed or vegetative material in various kinds of genebank or other facilities. Now the need to conserve CWR in their natural surroundings (in situ) is increasingly recognized. Recent research co-ordinated by Bioversity International has produced a wealth of information on good practices and lessons learned for their effective conservation. This book captures the important practical experiences of countries participating in this work and describes them for the wider conservation community. It includes case studies and examples from Armenia, Bolivia, Madagascar, Sri Lanka and Uzbekistan, which are important centres of diversity for crop wild relatives, and covers four geographical regions - the Caucasus, South America, Africa and the Asia-Pacific Region. It provides practical, relevant information and guidance for the scaling-up of actions targeting CWR conservation around the world.

Book Description
This study, prepared within the ambit of The State of the World’s Forest Genetic Resources, reviews issues related to the development of indicators for tree genetic diversity. It includes a historical account of the development of science-based indicators for tree genetic diversity that embrace ecological surrogates for genetic diversity, the genealogical approach, genetic monitoring of management units, the use of molecular markers, as well as relevant experience from other organisms and policy processes. It also includes a section on relevant data, data sources, and databases. Finally, the study proposes a set of four operational indicators for monitoring tree genetic diversity. The proposed indicators could support efforts towards sustainable forest management, as well as the development of indicators for the post-2020 global biodiversity framework.

Book Description
This book provides complete, comprehensive, and broad subject-based reviews for students, teachers, researchers, policymakers, conservationists, and NGOs interested in the biodiversity and conservation of woody plants. Forests cover approximately 31 percent of the world’s total landmass; 93 percent is natural forest and only 7 percent consists of planted trees. Forest decline is progressing at an alarming rate worldwide. In addition to human activities (logging, deforestation, and exploiting forest lands for agriculture and industrial use), a number of other factors – including pests and diseases, drought, soil acidity, radiation, and ozone – are cumulatively contributing to global forest decline. The present situation forces us to focus on forest conservation strategies for the present and future. Gene conservation and maintaining genetic diversity in forest ecosystems are crucial to the preservation of forest genetic resources. This calls for integrated action to implement both the in situ (on site) preservation of forest stands and ex situ (distant from the original site) strategies for the conservation of woody plants’ genetic resources. Selected priority areas include: 1) assessing patterns of genetic diversity and threats, 2) understanding the biological processes regulating genetic diversity, 3) assessing the impact of human activities and climate change on genetic diversity, and 5) finding methods for prioritizing species and populations for the conservation of forest trees genetic resources. All chapters were written by leading scientists in their respective fields, which include: woody plant diversity, ecology and evolution; assessment of genetic diversity in forest tree populations; conservation planning under climate change; and in situ and ex situ strategies, including biotechnological approaches, for the conservation of woody plants genetic resources.
