Name: Picea pungens / Lonicera involucrata Forest
Reference: NatureServe Biotics 2019
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. <i>Picea pungens</i> codominates, and the most important deciduous tree is <i>Populus angustifolia</i>. <i>Populus tremuloides</i> is present in small amounts. The shrub layer is primarily composed of deciduous species, with both tall and short shrubs abundant. <i>Lonicera involucrata</i> is the most abundant and constant, and <i>Alnus incana</i> commonly lines the riverbanks. Other shrubs present in smaller amounts include <i>Amelanchier alnifolia, Cornus sericea, Ribes inerme, Rosa woodsii</i>, and <i>Symphoricarpos rotundifolius</i>. The herbaceous layer is dominated by mesic-site perennial forbs, including <i>Maianthemum stellatum, Equisetum arvense, Geranium richardsonii, Heracleum maximum</i>, and <i>Rudbeckia laciniata</i>. Graminoids are generally sparse. Total herbaceous cover commonly exceeds 35%.
