Summary of Habitat: Sandy riparian areas areas in subzone C
Described from: Barrow
Common plant functional types and species:
Horsetail: Equisetum arvense;
- Streams in the coastal area near Barrow and along the northern coast of Alaska are incised into low marine terraces and often have deep snow in them during the winter. Slumping peat bluffs, constantly shifting stream channels, and occasional flooding by storm surges creates a mix of rudimentary plant species that are associated with a combination of riparian habitats, deep snowbeds, and saline coastal areas. The sites are often rich in species, but are highly variable in species composition. Equisetum arvense, Cochlearia officinalis, Alopecurus alpinus, Phippsia algida, Ranunuculus pygmaeus, and Stellaria humifusa are common species found in these sites.
