But predicting fall color is no easier than forecasting the weather. That's why the Arkansas Department of Parks and Tourism has a network of fall color spotters in every region who have volunteered to supply weekly updates. You can also order a fall Arkansas Vacation Planning Kit by calling either of these numbers. Travel consultants at the 13 Arkansas Tourist Information Centers located at major entry points into Arkansas also have fall color information in hand to advise travelers. Specific areas and highways are identified when possible.
Many people wonder what causes the leaves to begin changing color in the fall.
Contrary to popular belief, frost does not trigger this transformation. Most of the time, the first heavy frost does not occur until the period of color is nearly over. Leaves serve as factories where the tree's food is made. Chlorophyll gives leaves their green color. They use sunlight, carbon dioxide, water and other nutrients from the soil to provide the tree with food.
