Author @ the Library presents: "Mannahatta: A Natural History of New York City," with landscape ecologist, Eric Sanderson.

By geographically matching an 18th-century map of Manhattan's landscape to the modern cityscape, combing through historical and archaeological records, and applying modern principles of ecology and computer modeling, the author is able to re-create the forests of Times Square, the meadows of Harlem, and the wetlands of downtown. View breathtaking illustrations that show what Manhattan looked like 400 years ago.
