Summer drought and warmer temperatures lasting well into the fall in Maine have caused unpredicatability in the leaf peeping season. Warmer temperatures have delayed the onset of fall in Maine, pushing the color peak later. Other factors are also stressing Eastern forests. More intense storms, rainfall and invasive species harm trees and their leaves, and may already be reducing the vibrancy of fall colors and shortening the season. Scientists refer to fall as the most understudied season in climate change research. There are still a lot of unknowns. Yet, understanding the effects of climate change on fall phenology are critical for regions like Down East Maine, where fall tourism is a billion-dollar industry. Scientists and conservationists want Down East visitors to share that sense of stewardship, because the shifting leaves are a visible sign that change is already here.
