This is a personal account of Carl and Jane Bock's studies of ecological changes in an Arizona grassland following livestock removal in 1968. The Bocks summarize the results of 30 years' field work aimed at placing the ecological lessons learned at the ranch in a broader context of how humans are impacting the contemporary landscape of the American West.
