“…To decrease the costs of surveys, it should be tested if technical staff could be trained to sample macrolichens reliably in the field. So far, there is somewhat controversial evidence of the success of such an approach (McCune et al 1997;Will-Wolf et al 2002). Species determination could still be done by specialized taxonomists later in the laboratory.…”

“…The high costs thus associated with the assessment of microlichens is probably the main reason why they are frequently neglected. Macrolichens, on the other hand, are often assessed, sometimes even by trained technicians (McCune et al 1997;Will-Wolf et al 2006). It seems therefore obvious to test if macrolichen richness may serve as an indicator for microlichen richness.…”

“…Blind-checked plots are usually surveyed by a lichenologist within 1 month of the crew, without knowledge of the crew's data, and provide a measure of data quality. Air quality estimates from FIA gradient models have been found to be highly repeatable as long as the 65 percent criterion is met (McCune et al 1997). Uncommon (4 to 10 thalli) 3 Common (>10 thalli; species occurring on less than 50 percent of all boles and branches in plot) 4 Abundant (>10 thalli; species occurring on greater than 50 percent of boles and branches in the plot) To help build gradient models for air quality or climate bioindication, additional lichen surveys may be conducted at temporary plots off the regular FIA grid (i.e., off-frame plots).…”

“…A drawback to this approach is that different surveyors are likely to be more attuned to different taxa and habitats; were the same plot visited by multiple surveyors, they would likely result in somewhat different species lists. The same problem has been more thoroughly studied using the FHM method in forests and has been found to be sufficiently consistent to allow large-scale comparisons (McCune et al 1997); however, future research should determine whether this is also true for soil crusts.…”
