Name: Pinus albicaulis - (Picea engelmannii) / Dryas octopetala Woodland
Reference: NatureServe Biotics 2019
Description: This northern Rocky Mountain woodland association is described from mountains in Alberta, Canada. Stands of this woodland association are found at subxeric sites, thinly covered with colluvial deposits. They are located at high elevations, between 2060 and 2290 m (6750-7510 feet), on the upper portions of moderate to steep slopes, and occur on west-, northeast-, and south-facing slopes. Soils tend to be rapidly draining Orthic Regosols composed of at least 50% small rocks. Ground cover of rock and bare soil is relatively high (50-65%). This woodland association is codominated by a pole to mature, open tree canopy (&lt;20% cover) of <i>Pinus albicaulis, Picea engelmannii</i>, and <i>Abies lasiocarpa</i>. Heights of these species are between 5 and 15 m. The tree regeneration layer consists of <i>Pinus albicaulis, Picea engelmannii, Larix lyallii</i>, and <i>Abies lasiocarpa</i> with less than 20% cover. <i>Juniperus communis</i> is found in the sparse short-shrub layer, and <i>Dryas octopetala</i> dominates the dwarf-shrub layer with an average cover of 30%. The herbaceous layer is represented by a diversity of species that contribute moderate canopy cover (50%) and reflect the subxeric conditions. Common species include <i>Sedum lanceolatum, Anemone multifida, Festuca brachyphylla</i>, and <i>Saxifraga bronchialis</i>. Numerous nonvascular species and a few epiphytic species are found in these stands as well and make up&lt;20% total cover. Diagnostic of this associations is the <i>Pinus albicaulis</i>-codominated tree canopy with the understory dominated by the dwarf-shrub <i>Dryas octopetala</i> and subxeric herbaceous species <i>Saxifraga bronchialis</i>.
