What is the state of the planet's forests? Dr. Joan Maloof, author, ecologist and environmental advocate summarizes the condition of our forests from global and national perspectives.

She focuses particularly on forests that have never been logged -- "old-growth forests." How many of these forests are left? Where are they? And why do they matter?

Maloof has traveled the nation inspecting the remaining old-growth forests; in her book, Among the Ancients: Adventures in the Eastern Old-Growth Forests, she includes reflections on these questions as well as detailed directions to one old-growth forest in each of the twenty-six states east of the Mississippi River.

Going beyond mere documentation, in this lecture Maloof describes her vision of an Old Growth Forest Network -- a nationwide attempt to reverse past destruction and reconnect average families with the beauty and biological abundance found only in the ancient forests.

This was part of the 2012 Cornell Plantations Lecture Series.
