Chlorophyll a and b analyses of cryptobiotic crusts from burned and unburned sites on the Snake River plain provided an estimate of crust recovery. In less than 3 years, chlorophyll a levels were approximately 50% of the unburned reference site. Chlorophyll a/b ratios indicated that the biotic composition of the recovering cryptobiotic crust consisted largely of eukaryotic algae and bryophytes.
