‘TIS THE SEASON: Bad news for allergy sufferers. The drought’s over, so trees in Orange County are back to filling the air with enormous amounts of pollen (E1). . . . The worst offender is still relatively dormant, however. Olive trees in this region cause more allergy misery than any other tree, says Dr. Mark H. Ellis of Orange, adding: “Olive season is not fully upon us. It peaks around April, and it’s going to be very heavy this year.”
These five trees last week produced the most pollen units per cubic meter of air in Orange County:
Tree Units % of O.C. pollen Oak 150 22 Mulberry 130 19 Sycamore 120 18 Pine 70 10 Liquidambar 70 10
