Through the seedling emergence method we studied the effects of fi re on the soil seed bank of a xerophytic shrubland in two consecutive years. We compared its composition and abundance in two sites, one burned and one unburned. An important proportion of seeds died due to the high temperatures reached by fi re. In addition, species richness and, diversity were also negatively affected. These variables showed statistical differences between sites and years. After one year, seed bank abundance and diversity reached higher values. Dominant species were perennial herbs in terms of species number, and in terms of seedling abundance the dominant life form was a tree. However, fi re was not a determinant factor in terms of species composition. These results are important to explain the changes in vegetation after a fi re, specially if we consider that this site is a natural preserve immersed in an urban area. |
