In response to a need for biological data on the virtually-unexplored forests of Irian Jaya, scientists surveyed the Waponga River Area and discovered many new plant and animal species, highlighting the importance of the area for conservation and illustrating the scientific world's limited knowledge of the region's flora and fauna. This book provides the results of that intensive survey, which included vegetation, aquatic insects, ants, fish, amphibians, reptiles, birds, and mammals.
