Dr. Stanley A. Temple, senior fellow at the Aldo Leopold Foundation, will give two presentations on Wednesday, March 21, both in CNS C101.

At 11 a.m., he will discuss “Aldo Leopold and ‘the Oldest Task in Human History'” (which Leopold defined as “living on a piece of land without spoiling it.”)

At 7 p.m., he will speak on “Aldo Leopold, Phenology and Climate Change.”

Aldo Leopold, the father of wildlife management who was best known as the author of A Sand County Almanac, was a keen observer of the natural world. Throughout his life he kept daily journals recording observations of seasonal events, especially those occurring at his beloved “shack” on the Leopold farm, which was the setting for many essays in A Sand County Almanac.

Leopold’s meticulous observations provided an unparalleled record of when plants bloomed, birds migrated and other natural events. Comparing his observations of hundreds of natural events to recent records helps us understand how climate change is affecting the ecological community.

These talks are supported by the Beach Lewis Fund of the Biology Department and are cosponsored by the Biology Department, the Environmental Studies program and John Wesley Powell Audubon Society.
