The epiphytic lichen Parmelia caperata collected in San Rossore park was analyzed for trace elements. Metal deposition in the park was found to be low throughout the year. A slight increase in Cu, Co, and Ni occurred at the east-southeastern edge of the park adjacent to Pisa. Lichens ware not affected by the sea-spray which has destroyed the coastal vegetation. The contrast with the results of previous pine needle biomonitoring is discussed.
