In mountainous regions, the slope or side of a mountain that faces the sun and receives the most sunlight.
From French 'adret,' derived from 'à droit' (to the right), referring to the sun-facing slope, used especially in Alpine geography.
The adret versus the 'ubac' (shady slope) creates two dramatically different ecosystems on opposite sides of the same mountain—the sunny side is warmer, greener, and supports different plants and animals.
