Abstract. Belguidoum A, Haichour R, Lograda T, Ramdani M. 2021. Biomonitoring of air pollution by lichen diversity in the urban area Setif, Algeria. Biodiversitas 23: 970-981. The use living organisms quality monitoring has received increasing attention recent years. Lichens, pioneer and colonizing organisms, are directly sensitive to environmental changes. This results a loss vitality or complete destruction thallus. objective this study is assess map Setif region, Algeria lichens, using bio-indication indices. For assessment, species frequency, Shannon-Wiener index, Atmospheric Purity Index (IAP), Air Quality (IAQ) were used. Sixty stations sampled across representing various level landscape factors anthropogenic activities. recorded 54 areas belonged 29 genera 19 families, which crustose foliose, most common region. indicators (IAP, IAQ) showed an important correlation between them difference rural ecosystems. Anthropized very high pollution. probably due industrial agricultural activities, but especially gas emissions from vehicles. majority studied with atmospheric In addition, presence Xanthoria parietina all facilitates it as reliable biomonitor plant tolerance pollutants
