Abstract: 2 tables. [Three-year study carried out at Anaktuvuk Pass, Alaska, using Cladonia stellaris, C. rangiferina and Cetraria cucullata. "The lichen vegetation which had experienced the greatest SO2 stress during the 1978 fumigation remained photosynthetically inactive. Significant photosynthetic recovery was discovered in the test species which had experienced sublethal concentrations of SO2; however, their photosynthetic capacities remained less than controls."]
