Local Environmental Conditions
This site in Bear Valley Springs is surrounded mainly by open grassland, which covers around 79% of the nearby area. With running water close by, riverside vegetation contributes to the local mix. Grass pollen adds noticeably to the overall load. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Across the year, tree flowering starts the season, reaching its height around early spring. Grass flowering starts in mid-spring, is strongest around late spring and winds down by midsummer. Later, weeds flowering on open and disturbed ground keep some pollen in the air from early summer into early fall. Locally, winters average around 10°C and summers around 30°C, with most rain falling in the cooler months.
