Name: Picea pungens / Lonicera involucrata Forest Reference: Western Ecology Working Group of... Description: This association occurs along rivers and streams of the west-central and southwestern slope of the Rocky Mountains in Colorado. Elevations range from roughly 2285-2625 m (7500-8600 feet). The valleys where it is found are narrow to moderately wide. It occurs on narrow alluvial terraces and benches adjacent to the channel, usually 1-2 m above the high-water mark. Parent materials are gravel and cobble alluvial material, usually within 1 m of the soil surface. Soils are highly stratified due to depositional events. This is a riparian forest association, characterized by a mixture of deciduous and evergreen trees in the canopy. Picea pungens codominates, and the most important deciduous tree is Populus angustifolia. Populus tremuloides is present in small amounts. The shrub layer is primarily composed of deciduous species, with both tall and short shrubs abundant. Lonicera involucrata is the most abundant and constant, and Alnus incana commonly lines the riverbanks. Other shrubs present in smaller amounts include Amelanchier alnifolia, Cornus sericea, Ribes inerme, Rosa woodsii, and Symphoricarpos rotundifolius. The herbaceous layer is dominated by mesic-site perennial forbs, including Maianthemum stellatum (= Smilacina stellata), Equisetum arvense, Geranium richardsonii, Heracleum maximum (= Heracleum lanatum), and Rudbeckia laciniata. Graminoids are generally sparse. Total herbaceous cover commonly exceeds 35%.  Accession Code: VB.CC.21470.PICEAPUNGENSLON Plot-observations of this Community Concept: 0
