84 SOIL SEED BANK AT WAGOMUWA NATIONAL PARKgrassland despite that it was not statisticallysignificant (Fig. 4).A total of 42,054 seeds germinated from all soilsamples, 64% of which were grasses. The meandensities of seeds of grass species weresignificantly higher in the grassland and at theecotone (Fig. 3; one way ANOVA: P < 0.001). Thedensities of seeds of other species except grasses,(i.e., other herbs, shrubs and trees) also variedsignificantly with the distance along transects(Fig. 5; one way ANOVA: p = 0.003 for herbs; P
