 abstract={Seedling mortality in natural populations of annual, biennial and perennial psammophyte species was investigated for seven years. The mortality of seedlings was found to vary little from year to year, and to be dependent primarily on the length of the life cycle and mode of reproduction of the particular species. The largest percentage of dead seedlings was recorded for the populations of perennial species, capable of vegetative propagation. A close (in general) relationship was found between the mortality of seedlings and their density. In a high-density_population the most likely to survive were those seedlings which were the first to appear in the population.},
