Centres of plant diversity : a guide and strategy for their conservation, v.2. Asia, Australasia and the Pacific
1995
The rationale for this three-volume work covering nearly 250 major sites for conservation of plant diversity worldwide is concern about rapid global loss and degradation of natural ecosystems. By highlighting areas of prime botanical importance, it is hoped that their conservation will be ensured by an adequate commitment of resources. Selection of the sites is based both on floristic statistics and on detailed first-hand knowledge of numerous botanists.
