Squirrels are responsible for planting more Oak trees than all humans

 

"Tree squirrels are one of the most important animals for helping oaks spread, because they store acorns in the ground, practically planting baby oak trees," says Smallwood. The researchers note that evidence is accumulating that along with blue jays and a few other small animals, squirrels are important in maintaining and regenerating second-growth oak forests, and may even have been responsible for spreading the vast stands of oak throughout North America.
