Local Environmental Conditions
The landscape around the heart of Shire of Colac Otway is heavily wooded, with some open grassland. The surrounding woodland makes trees an important local pollen source. Grass pollen is significant here, and plantain contributes weed pollen. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Tree pollen comes first, peaking in early spring. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. The season closes with plantain from mid-spring into early fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen.
