About Pollen in Richmond
Richmond’s spring allergy season (March-May) has high Oak (Quercus) and Red Maple (Acer rubrum) pollen; Oak is common in the James River Park System; Red Maple is dense in the Fan District. Pine (Pinus) pollen is heavy near Bryan Park and Maymont. Summer (May-August) has Grass (Poaceae) pollen; levels are high near Belle Isle and James River banks. Late summer has Ragweed (Ambrosia) in open fields.
The James River valley traps pollen during periods of high humidity; moisture is a factor in allergen persistence. Autumn and winter have high Mould (Alternaria, Cladosporium) spore counts; spores are from leaf litter in Forest Hill Park and damp river environments.
