Biodiversity, Australia State of the Environment Report 2001 (Theme Report): The meaning, significance and implications of biodiversity (Megadiverse countries) Australia State of the Environment Report 2001 (Theme Report) Prepared by: Dr Jann Williams, RMIT University, Authors Published by CSIRO on behalf of the Department of the Environment and Heritage, 2001 ISBN 0 643 06749 3 Megadiverse countries Australia is identified as a megadiverse country. The concept of megadiversity is based on the total number of species in a country and the degree of endemism at the species level and at higher taxonomic levels. The World Conservation Monitoring Centre recognised 17 megadiverse countries in July 2000 including Australia, Brazil, China, Colombia, Democratic Republic of the Congo (DRC) (formerly Zaire), Ecuador, India, Indonesia, Madagascar, Malaysia, Mexico, Papua New Guinea, Peru, the Philippines, South Africa, the United States of America (USA) and Venezuela.

Together, these 17 countries harbour more than 70% of the earth's species (Figures 1 and 2). Source: Conservation International (2000) Tree of Life Web Project. The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny).

Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things. ‪Biodiversity - from "The Wild Classroom"‬‏ Biodiversity - Vancouver Film School.
