Tree Ecology

As a graduate student exploring the rain forests of Australia, Meg Lowman realized that she couldn’t monitor her beloved leaves using any of the usual methods. So she put together a climbing kit: she sewed a harness from an old seat belt, gathered hundreds of feet of rope, and found a tool belt for her pencils and rulers. Up she went, into the trees. Forty years later, Lowman remains one of the world’s foremost arbornauts, known as the “real-life Lorax.”

America was built on white pine. From the 1600s through the Civil War and beyond, it was used to build the nation's ships and houses, barns, and bridges. Yet this popularity came at a cost: by the end of the nineteenth century, clear cutting had decimated much of America's white pine forests. In White Pine, ecologist and writer John Pastor takes listeners on walk through history, connecting the white pine forests that remain today to a legacy of destruction and renewal.
