ДИНАМИКА ЗАРАСТАНИЯ БОЛОТ ПРЕДКАРПАТЬЯ

В статье поданы результаты десятилетнего мониторинга флористической структуры современных болот Прикарпатья. Авторами сделан вывод, что негативные изменения связаны с влиянием как внешних климатических условий, так и внутренних фитоценотических и антропогенных факторов.

Ключевые слова: болотные угрупования, гигрофиты, лучные виды, семейство, вид

THE DYNAMICS OF OVERGROWING OF THE BOGS OF THE PRECARPATHIAN REGION

The article shows the results of the ten years monitoring of the floristic structure of current bogs in the Precarpathian region. The most typical sign of the disturbed floristic structure is overgrown the bogs’ territory with the meadow anthropochorous ruderal species and weeds. They intensively penetrate into highland cenosis from the neighbouring territories. These species are: Angelica sylvestris L., Rumex alpinum L., Senecio nemorensis L., Poa alpina L., Chamaenerion angustifolium (L.) Holub, Anthriscus sylvestris (L.) Hoffm. etc. The highland meadow-forest species also are widespread. Such species are: Solidago alpestris Waldst. et Kit. ex Willd., Doronicum austriacum Jacq., Senecio subalpinus Koch., Adenostyles alliariae (Gouan) A. Kerner, Heracleum carpaticum Porc., Luzula sylvatica (Huds.) Gaudin, Athyrium filix-femina (L.) Roth, Aconitum moldavicum Hacq., Symphytum cordatum Waldst. et Kit. ex Willd., Geranium alpestre Schur etc. The last ones take periphery plots of the bogs’ cenosis. They actively spread because of the process of alluvium soils out of the surrounding slopes. It makes positive conditions for seeds germination. The most competitive invasive species produce a large quantity of seeds, have a powerful root system and are able to the vegetative reproduction. The gradual penetrating of some shrubs and trees (Salix caprea L., Alnus incana (L.) Moench, Pinus mugo Turra, Picea abies (L.) Karst. etc.) indicates the changes of ecological conditions. Our investigation shows the changes of the vegetation: Phragmites australis (Cav.) Trin. ex Steud and Carex flava L. supplanted such species as Typha latifolia L. and T. аngustifolia L. Such meadow species, as Veronica longifolia L., Geranium prаtense L. and G. sylvaticum L., Galium verum L. form about 60 – 80%; 3-5 % – Lythrum salicaria L.; 2-3 % – Thalictrum lucidum L. The hygrophyte species (Myosotis palustris L., Orchis palustris Jacq., Gladiolus imbricatus L.) grow solitary or sporadically and form 2-3%. The authors made the conclusions that negative changes of the bogs’ flora are connected with outer climatic conditions and inner phytocoenotic and anthropogenic factors.
