Abstract: Moss cushions were sampled in the Allgäuer Alpen (Bavaria, Germany) during 1995 to compare the pollen assemblages from each site with the vegetational survey of 100 m² plots and the floristic records of bryophytes and vascular plants in a km² around the sites. The ensuing ratio between the two parameters is a raw measure of the degree of pollen representation and contributes together with the make-up of palynomorphs to the study of plant communities in the past and to environmental impact assessments. Some pollen types indicate environmental disturbance due to acid rain and anthropogenic effects, and may be integrated into the landscape-ecology approach.
