Air Quality: Anchorage Pollen and Mold Reporting

Date this count was performed:
May 5, 2015 


Tree pollen*  99 grains/cubic meter air High
Weed pollen  2 grains/cubic meter air Low
Grass pollen     absent
Mold spores Uncounted - low levels on slide 

* Tree pollen included populus (aspen/cottonwood group) and a small amount of willow and birch. Weeds, grass and many trees are yet to pollinate (see link for calendar below).

Mold spores become abundant during rainy periods, especially in the fall when plants are decomposing, providing good media for mold growth.     

Pollen and mold sampling and reporting is performed on Tuesday and Friday afternoons. Counts are avaialble also by calling the Air Quality Hotline at (907) 343-4899. The Department of Health and Human Services has developed a pollen calendar based on data collected in Anchorage in previous years. The calendar provides a general idea of when particular types of pollen are released and most prevalent in Anchorage. Click here for the Anchorage Pollen and Mold Calendar.
