Description Our results suggest that the soil thermal buffer allows fen species to escape frost temperatures in winter, but also high summer temperatures in warm regions, explaining their wide distribution ranges. The warm regeneration niche does not match the cooler soils, but shows variability and potential for adaptation. While these findings support resilience to climate warming, changes in precipitation rather than temperature seem to be the main threat for fen persistence.
