Another way for animals to help in seed dispersal is for the animals to actually plant the seeds themselves. Animals like mice, squirrels, and jay birds collect fruits and nuts during the spring and summer, and they store them for the coming winter. Many times, they save up these fruits and nuts by burying them in the ground - often more than they need. When they come to take their fruits and nuts away, they leave a few buried. The ones that are left buried become plants.
