摘要：

Dynamics of vegetation was studied on Stora Alvaret in bland, Sweden, in comparison with precipitation in the May-July part of the growing period. Three data sets representing three main life forms (shrub, dwarf-shrub, and herbs) were collected: species composition eight grassland permanent plots (1969-1993, ass. Veronica spicata-Avenula pratensis), survival and health status of Juniperus communis (1975-1993), and Calluna vulgar's cover at two permanent plots for the same period. Mortality of Juniperus and Calluna and proportion of annual species were synchronized and correlated with severe droughts.
