Local Environmental Conditions
Around 43% of the area near the center of Barstow, Texas is scrubland, with a good deal of bare ground and some open grassland. A nearby park adds mown lawns and planted trees to the local pollen mix. Locally, scrubland contributes pollen from shrubs, grasses and herbs. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Grass pollen follows, peaking in mid-spring and easing off by early fall. A smaller weed peak follows from early summer into early fall. In this dry climate, pollen can linger in the air for long spells without rain. By midwinter, as temperatures fall to around 10°C, pollen levels are low again.
