Name: Tsuga mertensiana - Abies lasiocarpa / Eucephalus ledophyllus - Lupinus arcticus Woodland
Reference: NatureServe Biotics 2019
Description: This association typically occurs as tree islands or ribbons in subalpine parkland. The tree canopy is dominated by <i>Tsuga mertensiana</i> and/or <i>Abies lasiocarpa</i>. Either can be absent. <i>Abies amabilis</i> is sometimes prominent to codominant. <i>Pinus albicaulis</i> sometimes occurs but does not codominate. A shrub layer is largely absent. The very well-developed herb layer is dominated by <i>Eucephalus ledophyllus, Lupinus arcticus ssp. subalpinus, Lupinus latifolius</i>, and/or <i>Polemonium pulcherrimum</i>. <i>Eucephalus ledophyllus</i> and <i>Lupinus arcticus ssp. subalpinus</i>, and/or <i>Lupinus latifolius</i> are at least prominent. <i>Luzula glabrata var. hitchcockii</i> is usually present to prominent. <i>Phlox diffusa</i> is sometimes prominent. <i>Vahlodea atropurpurea</i> is often present. If <i>Festuca viridula</i> 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.
