Ecological Indicator Information

A very shade-intolerant, sub­alpine to alpine, circumpolar evergreen dwarf shrub (trans­continental in North America). Occurs in alpine tundra and subalpine boreal climates on fresh to moist, nitrogen-poor soils (Mor humus forms); its occurrence increases with in­creasing latitude and duration of snow cover. Sporadic to scattered in heath communi­ties and parkland forests on water-shedding sites. Usually associated with Barbilophozia j1Derkeiand ericaceous shrubs. An oxylophytic species characteristic of alpine and subalpine communities.
