Local Environmental Conditions
This part of Rancho Tehama Reserve is surrounded mainly by woodland, which covers around 84% of the nearby area, with some open grassland. Close to a stream or river, riverside vegetation contributes to what is in the air. Trees are an important local pollen source, given how much woodland surrounds the area. Grasses add a sizeable share of the local pollen.
Month by month, tree flowering starts the season, reaching its height around early spring. Grasses are next, reaching their height around late spring and tailing off by midsummer. Weeds on open ground add a smaller late peak from early summer into early fall. Locally, temperatures range from around 5°C in the coldest month to around 30°C in the warmest, with most rain falling in the cooler months.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
