Abstract
The tree line is the upper margin of the subalpine forest where the trees become dwarfed or are absent (Howard &,Mitchell 1985). On topographic maps, the tree line divides the landscape into two uniform regions which are often referred to as ‘above’ and ‘below’ the tree line. The teminology implies a notion of the tree line as the physical manifestation of a continuous surface describing a potential tree level. The tree level exists globally, while the tree line only appears as a contour line where the tree level intersects the topography. The tree level can be thought of as a continuous but invisible surface. This surface cuts through the landscape along the tree line. The area below this surface is described as ‘below the tree line’, while areas above the surface are ‘above the tree line’.
