On one of the days of the symposium, field excursions to the mires of southern Karelia are planned. At the moment, two notable objects in the Pryazhinskiy district of Karelia are supposed to be chosen for the excursion.
Uchebnoe mire and adjacent landscape complexes of the Shuya river basin are located 50 kilometers from Petrozavodsk near the village of Matrosy (61°45’17” N, 33°43’22” E).
A landscape profile of about 3 kilometers length passes through coniferous forest on fluvioglacial and lake deposits, crosses the small oligotrophic bog Sosnovoye, a small eutrophic fen Klyuchevoye, confined to the outlets of ferruginous springs, and ends on the Uchebnoe mire with an area of about 140 hectares. This is a mesoeutrophic mire massif at the foot of the esker with a high variety of open and afforested communities. The landscape complex has been fairly well studied; 158 species of vascular plants (more than half of the flora of the Karelian marshes) and 56 species of bryophytes (approximately 40% of the Karelian bryoflora) were recorded in the marshes.

Rich fens of Kolatselga area. The old Karelian village of Kolatselga is located 130 kilometers west of Petrozavodsk (61°40’43” N, 32°14’09” E). About 30 small, 1-2 to 30 hectares of eutrophic fens are scattered around the village. During World War II, these mires were examined by Finnish botanists Jukka Lounamaa and Harry Waris; those studies were published after the war (Lounamaa, 1961). Kolatselga fens are characterized by high biodiversity and the occurrences of many rare species, which is due to the lining of these fens with carbonate rocks (dolomites). 180 species of vascular plants and 53 species of bryophytes were recorded from these mires. Here is the oldest mire of Eastern Fennoscandia, here is the easternmost occurrence of Sweetgale Myrica gale in Europe.
