In mid to late spring, here in upstate New York we have an approximately three-week-long pine pollen season when the predominant local conifers release an annual epic flood of pale yellow, microscopic pollen grains into the air. Depending on time of day and environmental conditions, the male pollen particles have evolved methods to protect their gamete cells while traveling great distances in a brief time, maximizing deposition over vast areas.
