Centres of Plant Diversity
This is a three-volume work published by the World Wide Fund for Nature and IUCN, and contains accounts of nearly 250 major sites for conservation of plant diversity. The work is based on the urgent need to highlight and therefore protect areas of prime botanical conservation. The sites covered have been chosen partly on the basis of floristic statistics. There is a Data sheet for each site. These sheets are set within a regional context, outlining threats to plant distribution, conservation efforts and additional sites.
