Epiphytic macrolichens in Estonian forests

Martin, L.; Martin, J.

Some 116 random sample plots were studied in Estonian forests to estimate epiphytic macrolichen distribution frequency: 57 lichen species were recorded 1164 times on 2328 trees (14 species, with the most frequent species Pinus sylvestris, found in 71 of the plots). Lichen species were divided into 7 frequency classes. Frequency class 1 (1-15 records) contained most of the species - 42 species belonging to 5 geographical elements.
