The spatial structure of coenopopulations of Prunus armeniaca L. depending on the steepness and exposure of the slopes was studied in the Intramountain Dagestan at three high-altitude levels. The greatest density of apricot massifs are on the gentle slopes of the Northern exposures and in areas adjacent to the river valleys. The density of the apricot trees (r=-0.45), and a variety of other woody species (r=-0.91) decrease on the southern slopes compared to the northern slopes as they are more eroded and steep, that leads to the formation of monodominant apricot forests. With increasing density and joint growth with other tree species, the apricot crown acquires a pyramidal shape, and at low density a hemispherical shape.
