The aims of this study were to describe the composition of seed bank from a relictic area of Espinal, to classify the seed bank according to the persistence of the seeds within, to compare between the seed bank and established vegetation of the area and to present pictures of the seeds that were found. According to our results, there are 44 species in the seed bank, representing 18 families. The best represented families are Poaceae with 12 species, and Asteraceae with seven species. When the comparison between the seed bank and established vegetation was carried out, we found that the occurrence of exotic species was great in theprior, being Chenopodium album the most frequent species and it also has the highest density. We also found 19 species in the transient seed bank, 14 species in the short-term persistent seed bank and 11 in the long-term persistent seed bank. The majority of species that comprise the persistent banks are native. The high frequency of native species in the persistent banks could be an important factor during the regeneration of the area.
