Nearly 700 species of plants may become extinct by the year 2000. Faced with this overwhelming prospect, plant conservationists must take advantage of every technique available. This unique work summarizes our current knowledge of the genetics and population biology of rare plants, and integrates it with practical conservation recommendations. It features discussions on the distribution and significance of genetic variation, management and evaluation of rare plant germplasm, and conservation strategies for genetic diversity. Case studies focusing on specific problems offer important insights for today's challenges in rare plant conservation. eng
