Aldo Leopold and the Mark of the Wolf's Tooth

By Cristina Eisenberg / On August 4th, 2011
In the early 1900s, while cruising timber as a young forester, American conservationist Aldo Leopold, founder of the science of wildlife biology, encountered a female wolf with her pups. The common wisdom of that era was that the only good predator was a dead one, so he and his crew opened fire. But as he stood there watching the “fierce green light” fade in the wolf mother’s eyes, he felt a sharp, surprising pang of remorse. It would take him decades to parse out his feelings about her death.

Three springs ago I visited the Leopold Memorial Reserve—the depleted Wisconsin sand county farm Aldo Leopold bought in 1930 known as the “shack.” In the 1940s he recorded in his field notes that without large predators such as wolves to regulate their numbers, deer were eating aspens and other trees and shrubs to death. I wanted to see whether this was still so.

And Winter Broke

By Cristina Eisenberg / On March 31st, 2011
In March I participated in a University of Nebraska literary retreat at the Platte River Whooping Crane Maintenance Trust. It was the climax of spring migration on the river, where sandhill cranes pause to feed during their 5,000 mile journey from Mexico to as far as Siberia. I spent my time there ensconced in a primitive blind with several eminent poets, bearing witness to the cranes' sempiternal return. Fossil evidence suggests that cranes have been stopping at this place on their journey north for the past 10 million years.
