Seed dispersal
Most nuts, like acorns, walnuts, and pecans are dispersed by both water and animals. The main way that they are dispersed by water is during flood times, or if their plants grow near a river or stream. Many nut trees grow near places that flood quite often. Though water is important for nut trees, it's not as important as it is for other plants, because many trees have roots that can grow a long way from the tree to find good soil and water.
