Bryophlora of the surveyed undergrowth was mainly represented by only species-moss Brachythecium salebrosum (Hoffm. ex
F. Weber & D. Mohr) Schimp. It occurred only near the soil on stem bases of the investigated understory. The bryophyte cover was
independent from the species identity of the undergrowth, but depended on the local level of anthropogenic impact, which expressed
mainly in removing of died adult trees. It was revealed that the moss occurred on the undergrowth only on the experimental plots
(each of 0,01 ha), where during last three years no less than 4 trees had died and were removed. So, it may be a good test of the level
of anthropogenic pressure in a managed forest coenosis.
