Forests serve as the lungs of the Earth and are an incomparable cosmos. Their complex biosphere is packed to the brim with versatility and biodiversity, and all of the flora and fauna have their own unique contributions to make to the forest. On that note, did you know that squirrels play one of the most important roles in preserving forests?

These little nut-nibbling animals do more than just being cute! Every year, when they start collecting food for the long winter, they’ll bury nuts and seeds everywhere. And every year, without fail, there’ll be some buried treasures that go forgotten by their owners. When spring finally comes around to displace winter, little trees will start springing up here and there – and the squirrels don’t even know what they’ve achieved!
