Tallgrass Prairie—Heritage & Innovation
The Persistence of Prairie and People: The Emergence of the Native Seed Industry in the Upper Midwest
Andy Olson explores the emergence of the native seed industry from the Dust Bowl until present day. A wide array of individuals - including growers, scientists, and government officials - have persistently utilized and advocated for the use of native vegetation in a political and cultural landscape often hostile to the idea. Only in the face of environmental and financial crises have farmers, private-industry, and government turned towards prairie as a solution.
Aldo Leopold, Paul Johnson, and a Land Ethic for Iowa (and Beyond)
Iowa has been home to many conservationists who have shaped the state’s landscape, and whose influence has reached far beyond the state’s borders. These include Burlington native son Aldo Leopold and Decorah farmer Paul Johnson. Curt Meine wrote the first biography of Leopold, and has just published a collection of Paul Johnson’s writings, We Can Do Better: Collected Writings on Land, Conservation, and Public Policy (Ice Cube Press). Curt will share stories of his work on these two conservation leaders and the connections between them—and what their legacies hold for Iowa today.
