Brigham Young University's Lichen Air Quality Biomonitoring Program (Herbarium of Non-Vascular Cryptogams) represents one of the largest and longest-running lichen biomonitoring programs worldwide, with nearly 500 permanent reference plots distributed across the Intermountain West. At each reference site, sensitive indicator lichens are selected for elemental analyses of 25 potential pollutants, with the aim of subsequent resampling every five to 15 years for ongoing evaluations of ecological health. Using elemental analysis (EA) data from the past 30 years, a model for large-scale monitoring has been developed with the aim to (i) improve interpretation of air quality using lichen bioindicators, (ii) establish a framework to integrate future EA samples for comparison to historical data, and (iii) develop a platform in the future to more effectively share these data with land management agencies, research groups, and the broader public. The model will be field-tested with new EA samples collected along the Wasatch Front.
