Structure and condition of Dactylorhiza fuchsii (Druce) Soo cenopopulations in southern taiga pine forests of sphagnum type

The results of studies conducted during the mass flowering Dactylorhiza fuchsii (Druce) Soo plants are presented in sphagnum pine forests subzone southern taiga Kirov region. Descriptions species’ habitats given. studied cenopopulations (CP) D. were sphagnum-type forests: grass-shift-sphagnum with spruce (CP1), maynik-blueberry-green-moss-sphagnum (CP2). ontogenetic structure populations is shown. have shown that spectrum CP1, predominant group individuals generative period, which accounts for 58 %. age this population right-sided type. In CP2, an approximately equal ratio observed individuals. High values number and renewal index CP2 indicate its stable condition. CP quite numerous, CP1 - 88 individuals, 239 biotopes under consideration, species occurs both as small scattered groups. Further monitoring necessary to assess state forecast their development.
