Erle Ellis, associate professor of geography and environmental systems, appeared on a Smithsonian Magazine blog this week. The post “Watch How America’s Lands Changes from Forests to Fields” shares maps that Ellis created to depict how land use in the U.S. has evolved over the past 300 years. Ellis maps anthropogenic biomes—”a matrix of human-altered croplands, pastures, towns and cities…’anthromes’ for short” to help readers visualize humanity’s effect on the landscape. This semester, Fall 2013, Ellis is a visiting associate professor of landscape architecture at the Harvard University Graduate School of Design.
