ABSTRACT
The seed bank and seed rain can be used as indicators to evaluate the recovery potential of an anthropic area. Our aims were quantify the number of viable seeds and estimate species diversity of bank and seed rain to assess the recovery potential of an area surrounded by agriculture. We installed 40 collectors to evaluate seed rain and collected soil samples for seed bank quantifications. We found 2,079 seeds in seed rain, comprising 43 species, being Lauraceae and Fabaceae the most abundant families. Seed bank was represented by 69 seeds of 23 species, predominating Asteraceae family. We observed high species diversity in seed rain (H’= 2.34 nats ind-1). Secondary species predominated in seed rain, while pioneer species in seed bank. In conclusion, forested area is in an advanced successional stage indicating a potential capacity of system under anthropogenic pressures.
