Biological Assessment and Criteria presents a state-of-the-art overview of the applications of biological assessments and biocriteria for water quality management in fresh waters. The book presents case studies which illustrate how bioassessment has been used to identify and diagnose water quality problems. It also provides examples of the use of qualitative and quantitative biocriteria as regulatory tools to complement water quality criteria and standards. The first book to present the technical foundation, rationale, program and policy relevance, and legal basis for the most accurate tools used to assess freshwater natural resource and regulatory efforts, this book provides useful and timely information for water quality managers.

Liberia s national forests are among the last refuges in West Africa for large migrating mammals. This volume summarizes the findings of a biodiversity survey of three forests as part of the Liberia Forestry Initiative, an effort to rehabilitate and reform Liberia s threatened woodlands. The survey found each forest to harbor a wealth of biodiversity and a significant number of species of conservation concern. Researchers here document the discovery of six species new to science, report eighteen newfindings for Liberia, and present conservation recommendations based on survey results."
