Local Environmental Conditions
The landscape around this location in Howitt Plains is heavily wooded. Macalister Springs keeps the ground around it moist, supporting dense vegetation that adds to local pollen. In the immediate area, the surrounding woods make trees an important source. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. Rain is heaviest in spring, often giving short breaks from high pollen levels. By late fall, as temperatures fall to around 10°C, pollen levels are low again.
