Abstract
In the Cairngorm Mountains of north-eastern Scotland the present tree-line, dominated by Pinus sylvestris and frequently running at 1600 ft. (490 m), is largely artificial and well below its potential level. Along one small section only does it appear natural. Here it reaches 2100 ft. (640 m). Tree seedlings showed a marked reduction in numbers above 2300 ft. (700 m). The natural (potential) tree-line is postulated at between 2000 ft. (610 m) and 2250 ft. (685 m), varying with topography and local shelter. Man, especially between the 16th and 19th centuries, has reduced the forest margins to their present level. Wind exposure, measured by simple experiments, is severe at and above the present tree-line. This, and biotic pressure, are preventing upward extension of the forest.
