How were the new pollen trap locations chosen?

The new pollen trap locations were chosen by the department, in consultation with experts from the University of Melbourne, Deakin University and the Bureau of Meteorology. They considered factors including levels of rye grass, expected wind directions and likely distribution patterns of pollen, historical peaks in asthma presentations to emergency departments, population size, and the availability of appropriate locations to house, operate, maintain and staff daily pollen counts seven days a week from 1 October to 31 December.
