Summary of Habitat: Stable dry to moist acidic sandy ridge crests in Northern Alaska
Described from: Atqasuk (Komárková and Webber 1980).
Common plant functional types and species:
- This type is common on dry acidic stabilized dune crests in the sand region of northern Alaska. It covers 3% of Komárková's Map 2 at Atkasuk. However, it is poorly described at present, with no good relevés. The only characterization is from Atqasuk where a summary table presents the range of cover values from an unknown number of relevés (Komárková and Webber 1980). Characteristic species are abundant Cassiope tetragona, Salix phlebophylla, Diapensia lapponica and abundant acidiphilous lichens.
