Airborne pollen is a health concern for many residents in Clark County. The Clark County School District (CCSD) and UNLV established the Pollen Monitoring Program to provide local pollen and mold spore counts in Las Vegas. The county-wide distribution of the sites is a unique feature of the program and makes it possible to monitor important data for the west, northwest, southeast, and UNLV ZIP codes. Regular monitoring and reporting of airborne pollen concentrations continues to help the community prepare for or avoid exposure.
