In two experimental nature gardens a strong increase of Rhytidiadelphus squarrosus (Hedw.) Warnst. was observed over the period 1980-2000. The species expanded on several soil types and in various grassland communities. Data on R. squarrosus from other parts of the Netherlands suggest that this is not only a local phenomenon. In various places a clear increase of the species was observed. The formation of a thick layer by the species seems to be a new phenomenon. Atmospheric deposition of nutrients may be an important factor in the increase of R. squarrosus.
