San Diego County Mammal Atlas

The diversity of mammals in San Diego County is greater than any other county in the United States, yet there has been no synthesis of their identification, distribution, natural history, or the conservation challenges they face—until now. The San Diego County Mammal Atlas will serve as the definitive guide to the mammals of San Diego County. More than a decade in the making, the 432-page, and full-color book covers the biology of all 91 terrestrial species and 31 inshore marine visitors known to have occurred here during recorded history (since 1769). Species covered in the book range from the desert bighorn sheep to the abundant California ground squirrel seen in neighborhoods across the county to the immense blue whale found along our shorelines.
