scatter hoarding
n.— «Every year, the squirrels plant a forest of pecan trees for me. They observe a practice called “scatter hoarding.” That means they harvest nuts and such and bury them all over the place. That way, no single raid by a competing nut eater can decimate an entire hoard at one time.» —“Pecans love extra rainfall” by Jessie Gunn Stephens Herald Democrat (Sherman, Texas) Sept. 13, 2007.
