Conceived in 1976, Urban Wilderness is part of an ambitious project aimed at documenting New York City's special natural features and diversified ecological sites. Joel Greenberg's photographs of these sites in various seasons have a quality not unlike images by Ansel Adams, creating a new and surprising view of various regions in the five boroughs of New York City. Jean Gardner's text discusses the history of areas pictured, borough by borough. This book is both beautiful and unique.
