What the predator plague cycle diagram shows:
- Summer: When beech seed flowers heavily, much seed is produced.
- Autumn: When seed is abundant, the rodent population increases rapidly.
- Winter: Stoats feed on abundant rodents.
- Spring: When the seed rots or germinates, plagues of rats turn to bird eggs and nestlings.
- Summer onwards: Stoat numbers explode and they also turn to birds for food.
