Endangered species

The dugong (Dugong dugon) is the only herbivorous mammal that is strictly marine. It has a range spanning some 37 countries, including tropical and subtropical coastal and island waters. This plan presents a global overview of the status of the dugong and its management throughout its range.

The South Asian region can be considered a herpetofaunal "hotspot" with its high degree of species richness and diversity of amphibian and reptilian fauna. Unfortunately, high population density and population growth are putting enormous pressure on the region's natural resources and ecosystems, and as a result five amphibian species and 31 reptilian species from this region are listed as globally threatened in the 2000 IUCN Red List of Threatened Species.

Este constituye el primer libro rojo para un grupo de vertebrados del Ecuador y utiliza de manera comprensiva los nuevos criterios desarrollados por la UICN para categorizar especies amenazadas de extinción, inclusive con las últimas modificaciones aprobadas para esta novedosa metodología por parte del Consejo de la UICN a principios del 2000.

The threatened species categories used in Red Data Books and Red Lists have been in place for almost 30 years. The IUCN Red List Categories and Criteria provide an easily and widely understood system for classifying species at high risk of global extinction, so as to focus attention on conservation measures designed to protect them.

Drawing on the IUCN Red List of Threatened Species, the world's most objective and authoritative inventory of species at risk of extinction, this publication combines awe-inspiring imagery with solid science and factual accounts. The result of a collaboration between industry and science, this dramatic new work conveys to the general public the urgency and scale of the current extinction crisis.
