White mountain-avens may cover entire ridges in the Alaska Range, associated with moss campion, black oxytrope, arctic sandwort, lichens, grasses, and sedges.
Today, introduced annual grasses, including various species of avens, brome, fescue, and barley, occupy most of the remaining grassland areas.
In the Arctic, extremely steep environmental gradients are frequent on a microtopographical scale and ecotypic differentiation has been demonstrated over such short distances for alpine timothy (Phleum alpinum ), Carex aquatilis , mountain avens , and purple saxifrage , all widely distributed plant species in the Arctic.
Genetic responses of arctic species to changes in climate and ultraviolet-B radiation levels
Polar semi-desert dominated by mountain avens ( '' Dryas octopetala ''), Ny Ålesund, Svalbard.
Effects of changes in climate and UV radiation levels on structure of arctic ecosystems in the short and long term
Such an effect was demonstrated for mountain avens ( '' Dryas octopetala '') on Svalbard during a warm period in early winter  (see previous subsection on projected temperature responses).
Phenotypic responses of arctic species to changes in climate and ultraviolet-B radiation
Alpine vegetation is also characterized by heather (Ericaceae) with sedges (Carex spp.) and mountain avens (Dryas hookeriana) on warmer sites.
The dwarf scrub communities are dominated by crowberry (Empetrum nigrum) and include other ericads (Vaccinium spp.), arctic willow (Salix arctica), and white mountain-avens (Dryas octopetala).
In the colder alpine regions, mountain avens (Dryas hookeriana), dwarf shrubs, forbs, grasses, and lichens constitute the main vegetative cover.
The alpine vegetation is typically tundra, and includes discontinuous patches of low-growing heather (Ericaceae), sedge (Carex spp.), and mountain avens (Dryas hookeriana).
Surface material deposits from glaciers and icefields form moraines which are colonized by lichens and mosses, horsetail Equisetum sp., willows Salix spp., fire weed Epilobium sp., and mountain avens Dryas drummondii.

"There was a trail of tiny black ants.... I flicked them off with a few stern swipes of my apron, and made a mental note to see about finding some avens root for repellent."
