This loss was due to changes in agriculture and forestry practices and the elimination of natural fires from the landscape.

The Colors of Autumn Fall is the time of year that several of our native tree species exhibit striking colors. Various shades of reds, oranges, yellows, and browns can be seen in a variety of habitats and on a number of different tree species.
Fall colors can differ from one year to the next.
The most vibrant colors occur in autumns with ample rainfall, warm, clear days, and cool nights. Yellow colors and orange colors are produced by pigments in the leaves called Xanthophylls and Carotenes. These pigments are present in the leaves all of the time, but they only can be seen whenever the chlorophyll in the leaf disappears with the advent of shorter days and cooler weather. Trees with the brightest yellows and oranges include Hickories, Florida Maple, Red Maple, Hophornbeam, American Elm, Yellow Poplar and White Ash. Red colors are present in leaves whenever sugars called Anthocyanins in the leaves are broken down by exposure to cold.
