Descripción
Sumario:[EN] The structure of forest-alpine tundra ecotone is studied, by means of the analysis of data taken along five slopes in Central Pyrenees. Four growth forms are typified on Mountain Pine (Pinus uncinata Ramond): pyramidal-trees, flagged-trees, open-mats and closed mats. Pyramidal-trees and closed-mats are zonal phenomena, being the extremes of the altitudinal·sequence; nevertheless, flagged-trees and open-mats are local phenomena not subjected to a clear zonality. The stunted growth forms (closed and open-mats) show differences in ecology and structure among themselves. The name "elfin wood" is proposed for former and the term "krummhotz" for the latter.
