Wow...our tree count has surged into the VERY HIGH range, courtesy of area oak pollen and host of other trees at 2123.96 grains/cubic meter. The oak constitutes some 67% of our total annual tree pollen yield and when the oaks start flowering our tree count shoots up. This looks to be the highest March reading 1998-2011 for tree pollen due to an early oak surge this year.
The count of about 2,124 is almost a four-fold increase from yesterday’s count of 568 grains / cubic meter. The highest tree pollen count on record is 4,539, set April 25, 2009. April tends to have the highest counts of any month.
