Аннотация:
В ходе экспедиционных исследований 2012 г. обнаружены и исследованы евтрофные болота, находящиеся вблизи северного берега оз. Воже, по составу и сочетанию растительных сообществ непохожие ни на одно из ранее встреченных болот. На них найдены редкие как для Архангельской обл., так и для России в целом виды Schoenus ferrugineus, Scirpus tabernaemontani, Carex serotina, C. panicea, Utricularia minor. Состав произрастающих на этих болотах растительных сообществ не позволяет отнести многие из них ни к одной из известных ассоциаций.



Ключевые слова: евтрофные болота, Архангельская обл, северный берег оз. Воже, сообщества, образованные Schoenus ferrugineus, Scirpus tabernaemontani, Calluna vulgaris

Название на английском: EXTREMELY RICH FENS OF THE NORTHERN COAST OF VOZHE LAKE

Аннотация на английском:
Three rich fens were found and studied at the northern coast of Vozhe Lake. The central parts of the fens are occupied by ridge-pool and ridge-lawn complexes with rare plant communities. The plant communities with dominance of Scirpus tabernaemontani and Schoenus ferrugineus occur in mire pools and on swampy lawns. There is the first record of Schoenus ferrugineus in the Arkhangelsk Region and the first one of Scirpus tabernaemontani in the southern part of the Arkhangelsk Region. The both plant species are cited in the Red Data Book of Vologda Region for the north-eastern coast of Lake Vozhe, the data used in the Red Book being collected in the late 19th—early 20th century. Scirpus tabernaemontani occurs in the communities formed by Schoenus and pine-herb-sphagnum and hypnum mosses. In addition, recorded in these communities are (1) Carex serotina, known before in the northern part of the Arkhangelsk Region only (Schmidt, 2005); (2) Utricularia minor, abundant in the mire pools and known before in 3 localities in the Arkhangelsk Region (Schmidt, 2005); (3) Carex panicea. We believe that the communities of Schoenus ferrugineus belong to the Alliance Bistorto-Caricion diandrae (Smagin, 2004) rather than the Caricion davallianae, even if some characteristic species of the former one are missing. The communities occurring on ridges and hummock of the mires are noteworthy. Sphagnum fuscum dominates in a moss cover but the communities look unlike those known for Sphagnum fuscum. Growing together are plant species with different ecological gradients, such as Empetrum nigrum, Calluna vulgaris, Comarum palustre, Thelypteris palustris, Epipactis palustris, Bistorta major, Carex panicea. Interestingly, Calluna vulgaris is seen abundantly and constantly, though it is missing on raised bogs in this part of European Russia, its eastern border of distribution on mires going along Onega Lake in Karelia and the Vyg River. Remarkable is an abundance of Thelypteris palustris, a rare species in the Arkhangelsk Region. Also interesting is lack of species typical of all types of minerotrophic mires, such as Menyanthes trifoliata and Equisetum fluviatile. The analysis of peat cores taken from two mires has shown that the mires are young and originated from the lakes. The botanical composition of peat is similar to present species composition of the plant communities.
