Name: Fraxinus latifolia - Populus balsamifera ssp. trichocarpa - Alnus spp. Riparian Forest Alliance
Reference: NatureServe Biotics 2019
Description: This alliance comprises streamside riparian forests dominated by <i>Populus balsamifera ssp. trichocarpa</i> and/or <i>Fraxinus latifolia</i> in the upper canopy. Stands can be composed of pure <i>Populus balsamifera ssp. trichocarpa</i> or <i>Fraxinus latifolia</i> or a mix of the two and may be codominated by other deciduous trees such as <i>Acer macrophyllum</i> and/or <i>Alnus rubra</i>. <i>Populus balsamifera ssp. trichocarpa</i> is always present and characteristic. This alliance is found in coastal lowlands from south-central Alaska to northern California. Elevation ranges from low to mid elevations (around sea level to 1000 m). Stands occur on active floodplains on well-drained alluvial soils that either experience overbank flooding or high water tables during the snowmelt or rainy seasons. Stands may also occur on higher terraces that are less likely to flood. This alliance may be found along large channels along the Columbia and Willamette rivers, to smaller channels. Stands may be far from an active channel, but are well within the active 100-year floodplain. This alliance does not include isolated hillside springs or seeps.
