Light can interfere with nocturnal hunting, birdsong, vegetation.*

Light and Leaf Abscission and Plant Dormancy - Calgary Center
The length of nighttime darkness is a critical trigger for many deciduous plants to start the process of losing leaves in the fall (abscission) and entering a period of dormancy. Phytochromes mediate abscisic acid, which is responsible for these two actions. Artificial nighttime light can "fool" a tree into retaining the chlorophyll in its leaves too late in the season when deep frosts kill the leaves. Instead, the tree should be turning the various compounds of leaves into sugars and bringing these nutrients down into the roots for storage prior to the leaves being killed off. Trees and shrubs continue growing into autumn because of artificial daylight and fail to harden properly before winter. To properly cope with winter extremes, trees need to create special leaf-like structures to safeguard next year's growth locales. We know these as buds. The protective covers on the leaf buds are actually highly modified leaves coaxed into growing that way by high concentrations of abscisic acid produced by the tree and controlled by phytochromes.
