Name: Populus angustifolia - Picea pungens / Alnus incana Riparian Woodland
Reference: NatureServe Biotics 2019
Description: This plant association is a common riparian woodland in Colorado. Elevation ranges from roughly 1950-2925 m (6400-9600 feet). Stands occur along moderate-sized meandering streams and rivers in narrow to moderately wide mountain valleys and deep canyons with moderate stream gradients. It occurs on floodplains, active channel margins, and stream terraces. The shallow soils are derived from cobbly alluvium. Stands have an open to moderately dense (20-60% cover), mixed deciduous-evergreen tree canopy with <i>Populus angustifolia</i> and <i>Picea pungens</i> codominant. Frequently, other conifer trees are present, but not as abundant as <i>Picea pungens</i>. The shrub understory is typically dense and diverse. <i>Alnus incana</i> is always present. The moderate herbaceous layer is diverse, provides up to 30% cover, and is dominated by various graminoids with low cover of often diverse forbs.
