Why Do Squirrels Bury Their Nuts (And Forget)?

That frantic digging and burying you see in autumn is a squirrel’s version of stocking the pantry. Squirrels practice ‘scatter hoarding,’ burying thousands of nuts in individual caches to retrieve later when food is scarce. But they don’t just rely on memory. They use a sophisticated spatial memory system, remembering landmarks to find their caches. However, they are not perfect. The nuts they forget are not a loss for the ecosystem; they are a gain. Those forgotten acorns often grow into oak trees. So while the squirrels might curse their memory, they are actually playing a crucial role as accidental foresters.
