I appreciate your concern, but I am not sure it applies to keeping nuts planted in the wild from being eaten by squirrels, or mice, or whatever wild animal. I go around the borders of my plots, not on the cultivated ground, and my production/consumption is pretty much a closed circle anyway.
Thinking about squirrels burying nuts, and then finding them, I don't think other animals think as we do, although it may sometimes appear that way. Magpies bury acorns in rough grass, they return for many of them, but there are enough left that it can be a major factor in reforesting. Close observation revealed that the bird were not remembering where the nuts were buried and forgetting some. Rather they were finding tussocks of grass with a particular appearance and burying and searching there. They would sometimes search the same tussock multiple times, on the other hand if the tussock changed shape from the shape they attended to they would leave it. I wonder if squirrels do something similar.
