Abstract: The vegetation constitutes barriers against the gas emitions and polluting sources promoted by the human activity. The scarce arboreal vegetation and the constructions establishmented at Universidad Pedagógica y Tecnológica de Colombia (UPTC) Tunja building lots, it brings up the reduction in air quality. About that, the lichenical flora in green areas of the UPTC, was used such as atmospheric contamination indicator, IAP (Index of Atmospheric Purity) was made, from the coverings of eleven species of lichens finding in 36 forofites (trees), of nine stations represented in an isocontamination map. The covering species representative is for example: Heterodermia albicans (67243 cm2) present in exposed roads areas; otherwise, with smaller covering Teloschistes flavicans (29 cm2). The IPA, indicate that less polluted station was three with (44.29) and the most polluted station was eight with (27.29). These data demonstrate that due to the recent constructions the lichenical vegetation hasn%B4t strengthened yet, further, the low forofites diversity doesn't allow the lichens growth. The result shows that UPTC campus is highly polluted, due to the lack of trees that flank the pollutants impact.
