Depending on grazing intensity and growing conditions, disturbances caused by large herbivores have strong effects on vascular plant communities. However, it is not well known how sheep grazing activity affects bryophyte communities in tundra ecosystems. The aim of this study was to assess the impacts of sheep grazing activity on the structure and composition of bryophyte communities in Iceland. Bryophyte communities were compared in three grazed and three ungrazed valleys, in two regions in Northwest and North Iceland. Sampling was stratified to allow for an investigation of different growing conditions with respect to exposure, elevation, and landform. Bryophyte layer depth, species diversity and abundance were measured, and species we...
