Pinyon Pine

Pinyon trees do not produce pine nuts every year. These delicious nuts can only be harvested every three to seven years. This irregular schedule prevents animals from adapting to an abundance of pine nuts and guarantees that at least some nuts will become new trees instead of a quick meal.
