Abstract: 9 tables. 5 figures. [Authors report a 50% decline in lichen diversity since the early 1900's, and "...at sites with high oxidant levels, marked morphological deterioration of the common species Hypogymnia enteromorpha was documented." Transplants showed marked deterioration after a year's exposure in the San Bernardino Mountains.]
