Abstract This study was carried out in Tarmaber district north shewa zone Ethiopia to determine the effect of plantation forest with management intervention on woody plant species diversity, regeneration and soil seed bank species composition in five different forest types, which are adjacent natural forest, managed Cupressus lusitanica, unmanaged C. lusitanica, managed Eucalyptus globules and not managed E. globules plantation forests. A total of 75 circular sample plots of 314 m2 were established along a transect lines. Soil seed bank analysis was done from soil samples collected in each of the plots (225 samples) to examine the similarity between the soil seed bank and aboveground flora. Different diversity index and ANOVA was used in SPSS software for analysis. The result showed that a total of 51 woody plant species was recorded in adjacent natural forest (41), managed C. lusitanica (27), not managed C. lusitanica (9), managed E. globules (22) and not managed E. globules (13) species. Regeneration of seedlings were 3538, 5567, 707, 1462 and 2524 mean stems ha− 1 for natural forest, managed C. lusitanica, not managed C. lusitanica, managed E. globules and not managed E. globules respectively. Unmanaged C. lusitanica plantations had significantly lower densities of mature tree stems ha− 1 as compared to managed C. lusitanica, managed E. globules and adjacent natural forest (F = 14.03, p < 0.05).Similarly in terms of sapling density ha− 1 unmanaged C. lusitanica was significantly lower from other forest types (F = 7.37, p < 0.05). However managed C. lusitanica had significantly higher seedling regeneration (stem density ha− 1) than other plantation and adjacent natural forests (F = 16.11, p < 0.05). Generally mean stem densities including tree, sapling and seedling of woody species among different forest types managed C. lusitanica was significantly higher among different forest types (F = 13.01, p < 0.05). From the soil seed bank a total of 22 plant species (20 native and 2 exotic) species were recovered. In different forest types the number of species recorded was in adjacent natural forest (19), managed C. lusitanica (11), unmanaged C. lusitanica (4), managed E. globules (7) and unmanaged E. globules (5). The similarity of the oil seed bank was more or less similar to the above ground flora with maximum Sorenson’s similarity values of 0.633. Generally with appropriate management intervention undergrowth vegetation and soil seed bank status in plantation forest had good species composition and diversity.

Different Seasons

Although exploring soil seed bank characteristics and dynamics is conducive to plant diversity protection and restoration, few investigations have been undertaken in the rocky mountainous area of North China. To address this research gap, qualitative and quantitative changes in soil seed bank characteristics over different seasons and elevations as well as potential causes for differences were examined, using data from 25 secondary forest communities in the Songshan area of Beijing, China. Nonmetric multidimensional scaling (NMDS) was used to test the similarity of the composition of the seed bank and the understory vegetation during different seasons. In addition, the structural equation model (SEM) was used to explore the direct and indirect effects on seed bank density. The results indicate that abundance and species richness decreased with elevation, with seed density reaching its maximum and minimum levels in April and July at all elevation levels, respectively. In terms of species composition, the understory vegetation was significantly different from the seed bank, and the proportion of herbaceous plants species in the seed bank was higher. Soil total nitrogen, available phosphorus and available potassium all changed with elevation, directly or indirectly affecting seed bank density. The application of seed banks present in topsoil from the rocky mountainous area of North China can be potentially used for ecological restoration. It is important, however, to consider the elevation and the season related to the removal of the topsoil to achieve optimal effects.
