Name: Populus tremuloides / Alnus incana / Betula nana - Ribes spp. Riparian Forest
Reference: NatureServe Biotics 2019
Description: This is a valley bottom, riparian forest known only from the Wallowa River valley in northeastern Oregon. The forests are found along the northern boarder of the Wallowa Mountains, in a limestone area known as Alder Slope, extending from Ruby Peak to Mount Howard. All the sites are extremely wet, with limestone substrates and numerous springs. The forest canopy is mixed <i>Populus tremuloides</i> and <i>Alnus incana</i>, which is almost a tree in these stands. The stands have a very diverse understory, dominated by <i>Betula nana</i> at 10-20% cover, but which also includes <i>Ribes</i> species, <i>Rosa woodsii, Cornus sericea</i>, and <i>Salix</i> species. The shrub understory is patchy, interrupted by small <i>Deschampsia cespitosa</i> or <i>Carex</i> openings, streams, and occasional bogs. Occasionally, individuals of <i>Picea engelmannii</i> or <i>Juniperus scopulorum</i> can be found, but these are both rare. Forbs, including <i>Corydalis caseana, Urtica dioica, Dicentra cucullaria, Aquilegia, Caltha</i>, and <i>Ranunculus</i> species, are important in patches under the shrubs.
