Pine (Species, Pinus sp.; Family, Pinaceae)
There are a diverse range of Pine trees planted in and around Canberra with over 20 species found in gardens and more extensiveparklands and plantations. They are wind-pollinated and produce copious amounts of pollen during August to November when "dust clouds" of pollen can be seen blowing from the trees or settling in ponds and pools leaving a distinctive yellow "smear" on the surface.
The pollen grains are large with a wing structure that facilitates long-distance dispersal on windy days. Pine pollen allergies are similar to other pollen allergies, and many people with pine pollen allergy are also allergic to grass pollen.
