Abstract: Lichens were studied on camphor (Cinnamomum camphora) trees of the same age along the road from Hangzhou airport to the city centre. The number of species declined from 14 close to the airport (13 km) to 0 about 5~6 km from the town centre. The pattern reflects that seen in many European, and North American cities and shown to be correlated with air pollution. It is therefore clear that lichens have considerable potential as cheap biomonitors of air pollution in the People's Republic of China. The most tolerant species was an apparently undescribed species of Lepraria.
