Keeping Track of Seasonal Events

Aldo Leopold was a keen observer of nature and kept journals recording the timing of many seasonal events, including those at his “shack,” the setting for many essays in “A Sand County Almanac.” Leopold’s phenological observations provide unparalleled historical records that help us understand how climate change is affecting the timing of seasonal events. For those who love nature and take time to observe it, keeping records enhances the value of our time enjoying nature.
