Tree and Grass Pollen and Mold counts for May 22, 2015. Grass 2, low. Weed, nettle, 2, low. Alder 37, moderate. Pine 80, moderate. Cedar 15, moderate. Ash 15, moderate. Mold 978, low. Note: The cotton fluffs flying through the air and collecting on the ground are the seeds from cottonwood trees that pollinated earlier in the year. Allergy symptoms now are caused by grass pollen, some residual tree pollens, early weed pollens and mold spores which are microscopic. The cotton fluffs are not allergenic and don't cause allergy symptoms, but could trap other allergens that could trigger allergic symptoms.
