I am seeing pollen floating around in the air. Why are you not reporting it?

Pollen is microscopic and typically unable to be seen with the naked eye when it is floating through the air. However, some seeds can be seen floating in the air. Cottonwood is a common example. However, by the time a cottonwood tree distributes it's "fluffy cotton" or seeds, it has actually wound down its actual pollination period. The cottonwood trees release the allergenic pollen before the seeds are produced and blown into the air.
