AbstractRecently, forest seed banks were proven to not only reflect former (decades-old) but also ancient (centuries-old) land use. Yet, as land-use intensity determines the magnitude of seed-bank changes in recent forests, this study aims to identify whether an ancient land-use gradient would also be reflected in the seed bank. On a forested 1600-year-old archaeological site, five different land-use intensities were mapped and sampled. Apart from seed density, species richness and composition, functional seed-bank types, defined by nine seed-bank-related plant traits, were related to the land-use intensity gradient. The land-use gradient from gardens to undisturbed sites was still clearly reflected in the soil seed bank. Six emergent functional seed-bank types, characterized by specific plant traits, changed significantly in abundance, parallel to the land-use gradient. In particular, dispersal agent (and related traits) proved an important explanatory trait of present (functional) seed-bank patterns. Poor dispersers (large and heavy seeds) were not found in the intensively used areas, contrary to animal-dispersed species. Wind-dispersers may have been inhibited in the extension of their distribution by recruitment bottlenecks (low seed production) and/or competitive exclusion. Additionally, the agricultural land-use probably introduced ruderal species into the seed bank of the most intensively used areas, yielding a simultaneous increase in vegetation–seed-bank dissimilarity with land-use intensity, eliminating present vegetation as a driver behind the differences over the seed-bank gradient. We conclude by arguing how coppice-with-standards management possibly maintained the seed-bank gradient.

In order to study the characteristic of soil seed bank in saline wetlands,samples from different land-use types of wetlands were selected.After the germination test,the results showed that the reserves of SSB in the four plots are huge,but the species composition is uncomplicated,the germinated seedlings are all coastal indicating halophytes.The differences between the four plots are obvious, P-value is almost less than 0.05.Artificial landscape wetlands have the largest variance coefficient.Compared with artificial wetlands,natural conservation wetlands show unique characteristic,it has the highest species richness,it has the stablest vegetation community structure,but the density of SSB is lowest for the low interference.Natural conservation wetlands have played important role in maintaining biodiversity.Therefore, the wetland ecosystem services should be fully taken into consideration when using wetlands.Appropriate protection of wetlands are needed,for it can helps to improve the ability of SSB in vegetation recovery.

The natural restoration capability of vegetation along the expressway is of vital importance for the slope revegetation and maintenance. The Margalef 's richness indexes (DMA), Shannon-Wiener's diversity index (Hp), Pielou's evenness (Jsw), Simpson Index (C), Importance Value Index (IVtr), Vegetation coverage and soil seed bank were used to assess the vegetation restoration capability of the expressway 25, Lu-Su section in China. Seventy-four quadrats ranged from 1 m X 1 m to 20 m X 20 m were studied and the analytical results indicated that Digitaria sanguinalis, Setariaviridis and Gramineae are the dominant species in the expressway slopes. Texture is the most important factor influencing the α diversity and vegetation coverage. Cinnamon soil is more suitable for the restoration compared with slopes the other kind of texture. The land use type and alien species invasion along the expressway are also vital important for the natural restoration. The soil seed bank in filling slope is more abundant than that of excavation slope. The natural restoration of vegetation along the expressway varies according to the site types and land use and most of the slopes have strong recovery ability.

Abstract Background: Wild radish (Raphanus raphanistrum L.) is an invasive weed in Ethiopia and hurting different land use types in the Horro district of the study area and fact, more research has not been done yet on the weed is highly infested and persisted for three decades. Therefore, this study was conducted to assess the weeds flora and seed bank status across different land use types in the Horro district of western Oromia, Ethiopia. Three locations and from each location five different land use were purposively selected and a 1m2 area of quadratic sampling techniques was used to record weed flora. From each quadrat, soil samples were taken having two soil depth levels (0-15cm and >15-30cm) to evaluate the soil seed bank of weeds. Results: The data of wild radish weed in different location and different land use types both field survey and greenhouse experiments were found a statistically significant difference (p<0.05) among the target action of land use types but there was found no significant difference among soil depths. More all less, the highest wild radish population was recorded from grazing land land followed by wheat crop land and among the locations, Gitilo Dale has the highest weed density. Among the weed flora, again wild radish was highly dominated weed species than the other weed species in all land use types and locations. From soil seed bank status of soil depth, high weed population was recorded at 0-16cm of second season weed emergence from pot and Gitilo Dale was the highest infected location at this season, while barley crop land was the highest infected among land use types in first season of weed emergence from pot. Among the weed species were recorded from soil depth, again wild radish was highly dominated in both seasons. The population of weed flora per quadrat was directly proportion with population recorded from soil depth that emerged from pot. Conclusions: This study has highly verified that this area has highly infected by wald radish (Raphanus raphanistrum) and there could be a source of weed seed. Generally, the concerned bodies should have to be given attention which should need immediate intervention strategies to mitigate the negative impacts of weed otherwise the area will be out of production soon. Therefore, an extensive integrated weed management strategies should be applied in all phases of cropping systems to sustain environment and reduce this weed in the future.
