General flowering (GF), a supra‐annual, irregular fluctuation in flowering and seeding at the community level, is a phenomenon unique to the tropical rainforests of South‐East Asia. To test the animal pollination and predator satiation hypotheses, which are the main hypotheses that attempt to explain the ultimate cause of GF, we conducted a bagging experiment after the flowering of Shorea pilosa (Dipterocarpaceae). Seed survival at the predispersal stage was divided into two stages (1–30 days and > 30 days after flowering) and we compared the results between treatments and between GF and non‐GF periods using a survival analysis. Survival during the GF period at both stages was significantly higher than during non‐GF periods, suggesting that both hypotheses were supported and that synchronous flowering with GF benefits the reproductive success of S. pilosa .
