Nature's Second Chance: Restoring the Ecology of Stone Prairie Farm by Steven Apfelbaum

There are few who have taken to heart Leopold’s vision more than restoration ecologist Steven Apfelbaum, who, over thirty years, transformed his eighty-acre Stone Prairie Farm in Wisconsin into a biologically diverse ecosystem of prairie, wetland, spring brook, and forest. In Nature’s Second Chance, the author captures the intimate relationship he has created with the land and shows how the restored farm is serving as a model for the human community around him.

Opening with his very first walk on the farm, this deeply personal account relates how Apfelbaum and his family worked to restore acres of native wildflowers and wildlife on land he found depleted after years of corn farming. The traditional agricultural community around him was at first deeply suspicious, he explains, but most of them came around to Leopold’s beliefs, as lived by the author, after seeing the benefits of restoration at Stone Prairie Farm. Nature’s Second Chance offers unique insights into the biological world, the processes of ecological recovery, and how humans might play a starring role in healing a planet by implementing Leopold’s land ethic, one farm, lot, or brownfield at a time.
