Parque Nacional Noel Kempff Mercado, located in eastern Bolivia where the moist forests of the Amazon meet the dry forests of the Cerrado, contains numerous unique ecosystems and exceptionally high levels of biodiversity. This book presents the results not only of an intensive biological survey of the area conducted in 1991, but also of long-term research conducted from 1987 to 1995. Among other findings, the survey discovered 26 new species of plants, one new mammal species, and three new species of reptiles. This report, with text in both English and Spanish, includes extensive data appendices, a large fold-out satellite map of vegetation, and conservation recommendations for the region.
