The methodology describes instructions for monitoring of 42 epiphytic, epixylic and saxicolous species. For every species, a map of historic and recent distribution, based on herbarium revision, literature excerption and field survey of selected localities, was made.
A card containing information about biology, ecology, distribution, and endangering factors, was compiled for every species. These cards are attached to the methodology.
Two recommend forms for recording monitoring data are another appendix of this methodology.
