Some plant species put out their seeds, or fruits, only periodically, and when they do, the seeding event can have far-reaching ecological impacts. In this interactive, explore one of the most well-understood mass seedings—that of oak-tree acorn crops—and its widespread effects on various animals in the ecosystem as well as on nearby human populations.

When oak trees shed huge numbers of acorns every few years, it has ramifications throughout the ecosystem.
