- Observation Four plant taxa characterize Tucson airborne pollen.
- Observation Mountain pollen of three taxa was transported to the study area.
- Method / resource Annual pollen capture was similar between Burkard and Tauber samplers.
- Observation Atmospheric pollen varied seasonally but had low annual variability.
- Observation Spatial variability in pollen among sites was low.
- Observation Pollen concentrations varied widely among sites.
- Observation Pollen taxonomic composition remained constant among sites.
- Observation Reentrained soil pollen made up 11% of airborne pollen.
- Observation Gramineae and Chenopodiaceae-Amaranthus made up 90% of reentrained pollen.
- Observation Pollen reentrainment varied seasonally.
- Association High temperatures, low dew point, and moderate wind were associated with maximum atmospheric pollen concentrations.
- Association Winds before summer storms increased pollen concentrations.
- Observation Pollen from soils showed deterioration.
- Observation Four plant pollen taxa were commonly found in soils.
- Observation Morus pollen was rarely found in soils.
- Observation Four taxa with thick pollen walls were present in low numbers and resisted destruction.
- Observation Seasonally collected soil samples had similar pollen spectra.
- Observation Inoculated soil pollen was initially well preserved but was rapidly lost.
- Observation After one year, seven of eight inoculated pollen taxa approached background concentrations, while Solidago remained an order of magnitude higher.
