Sumario:Vegetation dynamics in montane grasslands at Sant Jaume de Frontanya (Eastern Pyrenees). The study of the anual biomass variation of grasslands from Sant Jaume de Frontanya (Alt Bergueda, Barcelona), besides the analysis of phenological differences among communities, show that they are phased out, and adopt different models of development according to the degree of mesophily. The greatest variability in fresh weight among communities is related to exogenous factors, and the constancy in the increase of dry weight, to the combination of both exogenous and endogenous factors.
