Characteristic, dynamics and limiting factors of growth of Neckera pennata Hedw.in the vicinity of the Cherepovets industrial complex

The paper provides information on the locations of the populations of the protected epiphytic moss Neckera pennata Hedw. and a number of their characteristics in the vicinity of the Cherepovets industrial complex (Vologda region). The monitoring data (change in the number and projective cover of turfs) in two locations were analyzed. It revealed that the main limiting factor for the growth of moss is the microclimate conditions in the places where populations exist: air humidity (indirectly, soil moisture, undergrowth development) and illumination.
