This study examines the relationship between air quality and lichen diversity on trees in the median strip at Ban Khuan Intersection, Mueang Trang District, Trang Province. The objectives of this study are 1) To investigate the relationship between air quality and the number of lichen species found. 2)To analyze the diversity of lichen species growing on trees in the area.Three tree species were studied Palm, Indian Oak, and Sri Trang. From the study, different tree species had varying numbers and types of lichens. A total of six types of lichens were found, categorized into high-tolerance and tolerant groups. One species belonged to the high-tolerance group, while five species belonged to the tolerant group.Among the trees studied, the Palm tree had the highest diversity of lichens, with four species: Dirinaria picta, Dirinaria aegialita, Parmotrema praesorediosum, and Parmotrema grayanum. The Indian Oak had two species, both in the tolerant group: Dirinaria picta and Pyxine subcinerea. The Palm tree had the highest number of lichens, and the area surrounding the Palm tree was found to have the lowest air quality. Meanwhile, Sri Trang had the lowest lichen diversity, indicating the best air quality. The relative humidity was found to be highest in areas around the Palm tree.
