Soil seed bank is significant breeding source for vegetation restoration[11] and species-rich vegetation restoration,[12] as they provide memories of past vegetation and represent the structure of future population.[13] Soil seed bank did not very differ in overall seed density or species diversity,[14] and there was little relative between the species composition of the seed bank and the composition of the aboveground vegetation.[7][15] These two facts could lead to the conclusion that the species composition of the aboveground vegetation and the soil bank can differ.[16] Additionally, it is a key point that the relationship between soil seed bank and original potential to measure the revegetation potential.[17][18] In endangered habitats, such as mudflats, rare and critically endangered species may be present in high densities within the soil seed bank and survive between 50 years or a century.[19]
