Local Environmental Conditions
This location in Lysterfield South is surrounded mainly by woodland, which covers around 77% of the nearby area, with some open grassland. A stream or river nearby means riverside trees such as willow and plane tree are part of the local pollen picture. Among allergenic trees nearby, ash leads, followed by maple and oak. Grasses also feature strongly, alongside pigweed and plantain among the weeds.
Tree pollen peaks in early spring, when the weather warms to around 10°C and ash, maple and oak are in full flower. Grass pollen follows, peaking in early summer and easing off by early fall. The season closes with pigweed and plantain from early summer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels.
