The methodology describes instructions for monitoring of 3 lichen species (Bryoria bicolor, Bunodophoron melanocarpum, Sphaerophorus fragilis) which primarily occur on mossy boulders and rocky outcrops; for Solorina saccata occurring primarily in calciferous rocky fissures, and for Physconia muscigena in case of saxicolous occurrence. 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.
Recommended forms for recording of monitoring data are also attached to this methodology.
