Name: Agrostis sandwicensis - Pellaea ternifolia - Racomitrium spp. Alpine Bedrock & Scree Group
Reference: NatureServe Biotics 2019
Description: This barren to sparsely vegetated group is found on alpine slopes of higher mountains of Maui and Hawai`i. Vegetation, if present, is sparse and may include scattered grasses <i>Agrostis sandwicensis, Trisetum glomeratum</i>, ferns <i>Pellaea ternifolia, Asplenium adiantum-nigrum, Asplenium trichomanes</i>, lichens <i>Lecanora melaena</i>, and mosses <i>Grimmia</i> spp. and <i>Racomitrium</i> spp. Stands occur in alpine zones from 3000-4590 m (9835-14,000 feet) elevation. Sites are generally very dry and cold. Precipitation occurs infrequently during the winter months of October-March. Snow is typically present on summits during winter months and can occur down to 3000 m. Snow can remain year-round on higher-elevation northerly slopes. Nightly frosts are common and can occur down to 3000 m. Sites are wind-exposed with high solar radiation. Substrates include cinder, volcanic ash, and basaltic lava, but can include glacial moraine. Ground surface is mostly gravel and barren rock.
