What causes this yearly cycle, and what e o e F , n s A m , , i C d l determines which color the leaves turn? C C m m 9 A R A 3 A COLOR During spring and summer, leaves e 5 9 e C 9 r 1 9 3 c c o 3 4 actively produce foods necessary for plant 3 5 r e 5 m e 5 4 2 4 6 a m growth. This food-making process takes a 6 6 t n i i o s place in the numerous cells within the leaf. d n s V i Within these cells are Chloroplasts, which o D i s n e GUIDE contain the chlorophyll pigments that are i t p o a r responsible for the green color of plants. r s t m The leaves also contain lesser amounts of B e u n other pigments, primarily xanthophylls r e t (yellows) and carotenoids (yellows, oranges a and reds). u Most of the year, these other pigments are masked by the greater amounts of chlorophyll present in the leaves. But in fall, when changes in temperature and the period of daylight occur, the leaves stop their food-producing activity. Soon the chlorophyll begins to break down, the green color disappears, and the yellows, oranges and reds slowly begin to emerge, giving the leaves their fall splendor. The intensity of color is determined by the plant’s response to complex gradients of temperature and moisture. Fall weather conditions favoring formation of brilliant autumn color are warm, sunny days followed by cool nights with temperatures below 45˚F (7˚C). Sugar production increases during the daytime, but cool nights prevent movement of sugar from the leaves. From the sugars trapped in leaves, the red pigment called anthocyanin is formed. When fall weather is consistently cloudy or rainy, and the nights warm, the leaves usually have less intense coloration. The smaller amounts of sugar made during periods of less sunlight moves out of the leaves during the warm nights, reducing the conversion of excess sugars into pigments. Before the leaves gracefully spin from their leafstalk, a special layer of cells devel - ops and gradually severs the tissues that support the leaf. A small leaf scar is the only evidence that leaves once adorned these deciduous plants. —Anne Halford, Botanist Bureau of Land Management, Bishop Resource Office CALIFORNIA he Eastern Sierra region is laced with rugged canyons carved by rushing streams, and home to some of the finest fall color viewing anywhere. Autumn displays of golden aspen mingle with pine forest and contrast with T stark granite walls. Cottonwood and willow line stream banks and border alpine meadows. Above it all looms the towering Sierra Nevada mountain range jutting into the azure sky. The trees generally begin their annual color show in mid-September and, depending on Mother Nature and elevation, can extend into late October. Warm days and cool evenings mark this time of year in the region, making it not only perfect for viewing and photographing the fall splendor, but also taking part in the many recreational activities and events the entire Eastern Sierra region is famous for. A wide choice of accommodations and dining opportunities completes the picture. The Eastern Sierra in the fal l— a special time in a special place.
