Fall Is The Riot Of Colors

Fall Season : Take deep breath and enjoy nature at its best . Trees take beautiful Avatar 

It is fall season. This is the best season for watching trees gradually changing colors in US . These autumn colors are seen everywhere :  parks and woodlands, in the cities, countryside, and mountains. 

One can see the reds, oranges, golds, and bronzes of the mixed deciduous woodlands in Eastern part and in the West the bright yellows of aspen stands and larches contrasting with the dark greens of the evergreen conifers. 

The timing of color changes and the onset of falling leaves is primarily regulated by the calendar as nights become longer. None of the other environmental influences – such as temperature, rainfall, food supply – are as unvarying as the steadily increasing length of night during autumn. As days grow shorter, and nights grow longer and cooler, biochemical processes in the leaf begin to paint the landscape with Nature's autumn palette.

Different trees gives different colors , for example Oaks: red, brown, or russet,Hickories: golden bronze,Aspen and yellow-poplar: golden yellow, Dogwood: purplish red, Beech: light tan, Sourwood and black tupelo: crimson. The color of maples leaves differ species by species: Red maple: brilliant scarlet, Sugar maple: orange-red, Black maple: glowing yellow, Striped maple: almost colorless.
