Summary Interannual variability of seed production, masting, has far‐reaching ecological impacts, including effects on forest regeneration and the population dynamics consumers. It is important to understand mechanisms driving masting predict how plant populations ecosystem may change into future, for short‐term forecasting production aid management. We used long‐term observations individual flowering effort in snow tussocks ( Chionochloa pallens ) European beech Fagus sylvatica test endogenous resource levels weather variation interact masting. In both species, there was an interaction between cue resources. If reserves were high, even weak temperature cues triggered relatively high reproductive effort, depleted resources suppressed reproduction presence strong cues. Resource played dual roles suppressant prompter reproduction, allowing plants fine‐tune length intervals large seeding years regardless variable frequency. The immediate application mast models increasingly global afforestation efforts. Moreover, role response will dictate responses climate change.
