Abstract
The temporary variation of seed rain was evaluated in a cloudy forest of the Mamapacha hill in the state of Boyacá (Colombia). they settled 16 plots of 25 x 25 m. each one, covering a total area of 1 ha. in each plot, 5 traps were placed with a surface of harvest of 1.25 m2. the vegetable material was collected monthly during seven months. 51489 seeds were counted distributed in 17 families, 14 genus, 9 species and 7 unidentified. the seed rain was represented by the trees of the dominant canopy, although a great abundance of seeds of the family Orchidaceae was also find. the eight more representative morfospecies were: Miconia sp., Orchidaceae, Weinmannia sp., Asteraceae sp. 2, Clusia sp., Asteraceae sp. 3, Asteraceae sp. 1 and Brunellia occidentalis. the biggest quantity of seeds was presented concluding the dry time (february and march), and the minor in full rainy time (august), demonstrating that seed rain is influenced by the weather conditions of the region.
