ABSTRACT
The current study describes the composition and density of seed rain in one hectare of Caatinga vegetation. Forty seed traps of 0.25 m2 each were set, and visited monthly during one year. Were sampled 76 seeds m2 and 26 species. Tillandsia spp. (Bromeliaceae) contributed with the majority (49%) of seed deposition. There was no significative correlation between density of deposition of seeds and precipitation monthly. The seeds of woody plants (tree and bushes) were preferentially autochoric.
