Detailed descriptions of three patterned rich fens, located along the Hyland River, approximately 155 km north of the town of Watson Lake, are reported for the first time. Similar to rich fens farther south in boreal and montane Alberta, these fens are characterized by high species richness and a ground layer dominated by Scorpidium scorpioides and S. revolvens. Despite the similarities in dominant ground layer species, these northern cordilleran rich fens differ in water chemistry and in having a number of species characteristic of northern or coastal locations, and lack many of the characteristic rich fen species found to the south. Therefore, these Yukon rich fens represent a unique variation within rich fen peatlands and indicate that S. scorpioides and S. revolvens are not strictly confined to high Ca2+ conditions. This distinct combination of water chemistry and plant composition not only sets these Yukon fens apart ecologically, but also underscores their importance as habitat for rare and specialized plant communities. Protecting these fens would ensure these distinctive wetlands continue to serve as refuges for species with specialized habitat requirements. Additionally, The locations of 425 patterned fens in the Yukon are documented using SPOT 5 imagery, ESRI world imagery, and Google Earth Pro. Less than 10 of these patterned fens have been visited and surveyed and little is known about their vegetation and chemistry.
