Resumen
Persistence, distribution and dynamics of Astragalus nitidiflorus soil seed bank, a critically endangered
species of southern Spain, were studied during four consecutive years to determine their importance
to regenerate locally extinct patches of the only known A. nitidiflorus population worldwide. The
spatial distribution of seeds on the ground was highly influenced by the presence or absence of adult
plants and by the indehiscent character of the fruit. Results showed that most seeds were present in
the surface layer, inside fruit and close to the mother plant. Seed longevity was low in general, but
higher for seeds protected by fruit than for single ones after two years of burial. We discuss our results
in relation with other patterns of seed dispersal or viability in arid environments, that are generally
characterized by high spatial and temporal variability with a short–range dispersal. We concluded that
this species is able to form a short–term persistent soil seed bank ...
