Lichens are not found in populated area as Delhi is populated area whereas the hills are not much populated so this is the reason behind that lichens do not occur in Delhi whereas they commonly grow in hills

Anashuman Singh 7 years, 1 month ago

Lichens are perfect indicators of air pollution. Excessive air pollution kills them. Therefore, they grow commonly in hills where air pollution is negligible and not in delhi where the air is filled with pollution.
