Bryophyte vegetation of the rock outcrops of "Chortova Skelia" forest reserve
and its anthropogenic dynamics
A study of bryophytes cover of the rock outcrops of the "Chortova Skelia" forest reserve was carry
out. It was established that a significant variety of natural conditions of the studied object is a factor
of structural and functional differentiation of bryocommunities. The bryophyte vegetation was
represented by 6 eco-floristic groups, which depend on the phanerogamous vegetation, microclimate
and underlying substrates by varying degrees. Prodromus of moss vegetation, consisting of 4 classes,
7 unions, 20 associations (3 of which we consider as extinct) and 6 communities was compiled. It was
established that anthropogenic transformation of rock outcrops leads to significant changes in the
structure of the moss cover. It was investigated that serious changes were caused by the breaching of
the forest tent over the rock outcrops as well as the transformation of rocks with following destruction
of the humus layer. Outcrops complex of "Chortova Skelia" and its associated microhabitats are in
need of protection measures, aimed to preserve the beech forest and rocks. These protection measures
would help to provide living conditions for nemoral and petrophylic moss vegetations.
Key worlds: moss vegetation, rock outcrops, anthropogenic transformation, prodromus,
microhabitats.
