Abstract
Dynamics of vegetation was studied on Stora Alvaret in Öland, 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 ofJuniperus communis (1975–1993), andCalluna vulgaris cover at two permanent plots for the same period. Mortality ofJuniperus andCalluna and proportion of annual species were synchronized and correlated with severe droughts. *** DIRECT SUPPORT *** A02DO006 00003
