Pollen grains are particles released by plants that fertilize flowers on the same or other plants and cause them to produce seeds. While pollen is essential to many plants' survival, it can be a potent irritant for allergy suffers.  The American Academy of Allergy, Asthma, and Immunology classifies pollen levels as Low (only individuals extremely sensitive to these pollens will experience symptoms), Moderate (many individuals sensitive to these pollens will experience symptoms, High (most individuals with any sensitivity to these pollens will experience symptoms), and Very High (almost all individuals with any sensitivity at all to these pollens will experience symptoms; extremely sensitive people could have severe symptoms).  The numbers which characterize these levels are: 

Low: Grasses 1-4 grains/m3; Trees 1-14 grains/m3; Weeds 1-9 grains/m3.
Moderate: Grasses 5-19 grains/m3; Trees 15-89 grains/m3; Weeds 10-49 grains/m3.
High: Grasses 20-199 grains/m3; Trees 90-1499 grains/m3; Weeds 50-499 grains/m3.
Very High: Grasses >200 grains/m3; Trees >1500 grains/m3; Weeds >500 grains/m3.
