Ormosia hosiei (Papilionaceae) is a rare and endangered plant native to China. Currently, it is not understood how seed predation and dispersal by animals affect natural regeneration of the species. During the autumn of 2009, we investigated patterns of predation and hoarding by Edward’s long-tailed rats (Leopolda-mys edwardsi) and Chinese white-bellied rats (Niviventor confucianus) of Ormosia hosiei seeds using large semi-natural enclosures in Dujiangyan City of Sichuan Province, southwest China. Both rodent species ate Ormosia hosiei seeds, but their hoarding patterns differed. Chinese white-bellied rats larder-hoarded more seeds in the nest and thus may have a negative impact on seed dispersal while Edward’s long-tailed rats scat-ter-hoarded more seeds and thus may have a positive impact on seed dispersal. In conclusion, our study indi-cates that compared with other rodent species as seed predators, scatter-hoarding rodents as seed dispersers may play a significant role in seed dispersal and subsequent establishment of this endangered plant.
