The survivorship and reproduction of the annual halophyte Spergularia marina was studied during four years on three different sites on a Baltic seashore meadow. The survivorship showed variation both between years and between sites. The mortality rate was not density-dependent in spite of very high densities in some years. At two of the sites the seed output was related to density, but individuals differed in their reproductive capacity. Limitation of the flower production was the main reason for this difference. At the third site the length of the flowering season determined the reproductive output.
