Lichen Diversity in Two Locations with Different Air Quality in Bogor Regency

Abstract

Lichen, commonly called crustal moss, is a symbiosis between algae and fungi resistant to extreme temperatures. The purpose of this study was to assess the diversity of lichen species, composition of lichen species, and lichen response in two research locations with different air quality. The selected locations were determined by knowing the environmental characteristics including air temperature, air humidity and CO₂ air quality. The value of lichen species diversity in Agatis Street (2.03) was higher than KSR Dadi Kusmayadi Street (1.86). The composition of lichen found on Agatis Street is 8 species from 6 families, and 6 species from 3 families on KSR Dadi Kusmayadi Street. Lichen living on Jalan Agatis showed a brighter and clearer coloured talus response, the talus grew well and intact and formed colonies so that it had a wider talus cover. Lichen growing on KSR Dadi Kusmayadi Street has a paler and faded colour, the talus does not grow optimally so it grows in fragments and does not form large colonies so it has a smaller talus cover area.
