CEGL007372 Tsuga mertensiana - Abies lasiocarpa / Eucephalus ledophyllus - Lupinus arcticus Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Mountain Hemlock - Subalpine Fir / Cascade Aster - Arctic Lupine Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association typically occurs as tree islands or ribbons in subalpine parkland. The tree canopy is dominated by Tsuga mertensiana and/or Abies lasiocarpa. Either can be absent. Abies amabilis is sometimes prominent to codominant. Pinus albicaulis sometimes occurs but does not codominate. A shrub layer is largely absent. The very well-developed herb layer is dominated by Eucephalus ledophyllus, Lupinus arcticus ssp. subalpinus, Lupinus latifolius, and/or Polemonium pulcherrimum. Eucephalus ledophyllus and Lupinus arcticus ssp. subalpinus, and/or Lupinus latifolius are at least prominent. Luzula glabrata var. hitchcockii is usually present to prominent. Phlox diffusa is sometimes prominent. Vahlodea atropurpurea is often present. If Festuca viridula is present, it not abundant. This association occurs on northeastern slopes of Mount Rainier at high elevations and in Oregon. Sites are above continuous forest and below upper treeline, with well-drained, mesic to moist soils.
