New locations of rare vascular plant species on cut-over peat lands (on the example of Kirov Region)

Abstract

The paper presents the investigation data of 6 cut-over peat lands in central area of Kirov Region (on the example of Zuev, Orichev, Slobod, Kirov and Chepez areas). The authors found the new locations of 10 rare plant species enlisted in the regional Red Book and species that have limited distribution in a region or have narrow ecological range (Gymnadenia conopsea, Dactylorhiza fuchsii, Epipactis helleborine, Epipactis atrorubens, Platanthera bifolia, Trichophorum alpinum, Botrychium multifidum, Dryopteris cristata, Thelipteris palustris, Huperzia selago). They also describe the process of phytocoenoses. The study shows the development of new typical boggy plant societies as a result of secondary bogging (on the example of Trichophorum alpinum, Drosera rotundifolia, Carex nigra, Eriophorum vaginatum, Parnassia palustris). The paper estimates the state of rare species populations. The authors analyze the ability of the species to inhabit artificial landscapes and anthropogenically modified phytocoenoses. That shows an explerent component of ecological-phytocoenotic strategy. Secondary boggy landscapes can play the role of refugiums for the species which habitats were lost due to industrial impact.
