Ecology v. 69, no. 2, p. 497-507615023Summary: Examination of the spatial pattern of the seed bank of an old field in Maryland showed that it was composed primarily of annual and short-lived perennial species dominated by Juncus tenuis and Fragaria virginiana. Seed abundance decreased with depth in the soil. The seeds of all species generally had clustered distributions in the soil. However, there was no trend in mean cluster size within or among species, or at different soil depths. The lack of definite trends indicated that the spatial distributions of seeds are governed primarily by environmental factors, and to a lesser degree by biological factors.
