Cliff Hair Grass

Cliff Hair-grass, Deschampsia cespitosa subsp. or related species within the Poaceae, is a tufted perennial grass adapted to moist, rocky cliff habitats, stream banks, and alpine or subalpine meadows in temperate mountain regions of Europe and North America. The genus Deschampsia, the hair-grasses, includes delicate, fine-leaved grasses with elegant, open panicles of tiny, often silvery or purplish spikelets that catch the light in mountain settings. Cliff-dwelling forms occupy ledges, crevices, and rocky terraces on cliff faces, benefiting from the stability provided by the cliff substrate and reduced competition from larger plants. The leaves are narrow, rough-edged, and rigid, adapted to exposed, windy conditions. Hair-grasses form dense clumps or tussocks that stabilize thin cliff soils and provide habitat for invertebrates. The species is widespread in cool, moist montane habitats across the Northern Hemisphere and is generally not considered threatened. It tolerates a wide range of soil chemistry and is among the first grasses to colonize disturbed mountain terrain. Deschampsia species play important roles in alpine ecosystem dynamics, including interactions with soil crust communities and montane invertebrate fauna.
