We sampled 32 “encenillo” trees Weinmannia tomentosa16 in each fragment, using three subsamples per tree at three height levels, for a total of 32 samples trees and 96 subsamples. Relationship between epiphytic lichens, trace elements and gaseous atmospheric pollutants.

In conclusion, a protocol using biotypes instead of species can be implemented by non-specialists to monitor and quickly evaluate the conservation of these Andean forests.
