Environmental surveys

The Siwalik (Churiya) range is a fragile land system formed from sediments during the raising of the greater and lesser Himalaya. The area is considered one of the world's most important sources of the later tertiary fossils of mammals and provides a basis for much of our current knowledge about the evolution of fauna, especially primates and reptiles. The Siwaliks, ranging east to west, occupy an estimated 13; of Nepal's total land area.

A new millenium is a fine opportunity to reflect on humanity's relationship with the rest of life on Earth - its biodiversity. Are natural ecosystems and species essential to our own success? And are we destroying them? The answers lie within this unique volume. An essential read for environmentalists, businesses and students alike, this publication contains colour maps, tables and figures summarising the state of the planet.
