Name: Argyroxiphium sandwicense - Coprosma ernodeoides - Tetramolopium humile Alpine Scrub Group
Reference: NatureServe Biotics 2019
Description: This sparse to open alpine scrub group occurs on Maui and Hawai`i and is characterized by scattered dwarf-shrubs (5-20%) of <i>Argyroxiphium</i> spp., <i>Coprosma ernodeoides, Dubautia menziesii, Geranium</i> spp., <i>Silene struthioloides, Styphelia tameiameiae, Tetramolopium humile</i>, or <i>Vaccinium</i> spp. Also present may be scattered grasses <i>Agrostis sandwicensis, Deschampsia nubigena, Trisetum glomeratum</i>, forbs <i>Pseudognaphalium sandwicensium</i>, ferns <i>Pellaea ternifolia, Asplenium adiantum-nigrum, Asplenium trichomanes</i>, lichens <i>Lecanora melaena</i>, and mosses <i>Grimmia haleakalae, Racomitrium</i> spp. Stands occur on dry alpine slopes from near 3000 to 3400 m (9835-11,150 feet) elevation and may extend down into the upper subalpine zone. The wet tradewinds frequently do not rise above 1900 m, being suppressed by the tropical inversion layer, leaving this alpine zone too dry to support wet vegetation. Annual precipitation is generally 750-1250 mm and falls from October to March, often as snow. Sites are wind-exposed. Frost is frequent, even during summer months. Substrates are well-drained and gravelly and derived from cinder and ash, and they can include glacial moraine.
