ABSTRACT. Four-year observation on growth of Pleurozium schreberi in Moscow Province and nearby are summarized. The species is characterized by explosive growth in the periods of continuous rains, whereas dew and even short-term strong rains do not affect its growth. In rainy periods within 3-5 days the increment sometimes exceeds 10 mm. Obtained data of annual increment of 16-75 mm are much higher than previously reported values for this species. Autumn growth is continuous before the temperature drops below +5°С, whereas in spring the growth delays up to and during late May and June. Growth in different habitats differs in its values, but the overall pattern of increment dynamics is the same.
