The Grinnell resurvey project. Surveys of the vertebrates of Yosemite National Park, California, were initiated by Joseph Grinnell in 1914 and continued by James L. Patton and colleagues in 2003. Using Grinnell’s detailed specimen locality data, field notes, and photos, researchers were able to replicate closely his sampling efforts nearly a century later. The result is an unprecedented look at biotic responses to nearly a century of environmental change
