Fall coloration publications
Why Leaves Change Color is a colored brochure developed by the USDA, Forest Service. It provides information on the following questions. How does autumn color happen? Where do autumn colors come from? How does weather affect autumn color? What triggers leaf fall? What does all this do for the tree? What happens to all those fallen leaves? Where can I see autumn color in the United States? When is the best time to see autumn color? This brochure unfolds as a 23 x 9-inch sheet that could be used as two posters (both sides include information and photos).
