This volume investigates the status and ecological significance of protected nature reserves across the Himalayan and Central Asian mountain ranges. The author, Michael J.B. Green, utilizes extensive field data and regional reports to document the biodiversity and conservation challenges within these high-altitude environments. The text provides a systematic framework for understanding how protected areas function as essential buffers for wildlife and ecosystems in Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal, Pakistan, and the former USSR.

Experts recognize this work as a foundational reference for conservationists and geographers focusing on Asian mountain ecosystems. Readers frequently note the technical density of the data, which serves as a vital historical record for environmental researchers.
