ABSTRACT
Seedbank dynamics, seedling emergence and survival of herbaceous species were studied in four successional plots each of dimension 25×25 m in Ile-Ife, Southwestern Nigeria between 1999 and 2001 using seedling emergence method in the screenhouse. The result of the study shows that, species belonging to the families: Euphorbiacea, Poaceae, Asteraceae and Urticaceae dominated the seed bank of the study plots. Total Seedbank density ranged from 1986 seedlings (14115 seed m-2) in older secondary forest plot to 3650 (21420 seed m-2) in managed plots. The mean seedling density also ranged from 8.95±8.03 to 71.72±3.42 seedling m-2. Seedbank density of the herbaceous species reduced significantly as the successional age of the plots increases and also across the 3 seasons in which soil was sampled: March, June and October. Two pattern of seedbanking were shown by the herbaceous species: transient and persistent. There was however no significant difference in species composition among the plots and across the seasons.
