Monitoring air quality with lichen: A feasibility study

  • Author(s) / Creator(s)
  • A study was undertaken in 1975 to determine the scientific, technical and economic feasibility of establishing air pollution effect gradients using lichenological methods on a radially arranged pattern of observation sites. The data acquired from 12 lichen sample plots indicate that the flora is sufficiently rich and widespread to allow establishment of a lichen air quality monitoring system. A grid network, containing 56 permanent plots, will provide adequate coverage of the region. Partial resurveys should be conducted annually, at least during the first years of the Syncrude plant's operation. Complete resurveys will only be required if a partial resurvey indicates adverse changes are occurring.
