Is that why pollen counting is only done for part of the year?

Correct. We begin counting in November when grasses start flowering when levels of grass pollen in the air start to rise. Most grasses in Queensland are the subtropical types that flower throughout summer and autumn giving Brisbane an extended grass pollen "season". Often the airborne grass pollen levels peak around February, depending on the weather. During the grass pollen season the count is done daily and the information distributed through various media outlets, this website and our twitter feed (@BrisbanePollen) and Facebook page.Correct. We begin counting in October when grasses start flowering when levels of grass pollen in the air start to rise. By January and February, the levels of grass pollen in the air begin to fall as the flowering season ends and the grasses start dying off.
