Name: Populus tremuloides / Alnus incana / Betula nana - Ribes spp. Forest
Reference: Western Ecology Working Group of...
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 Populus tremuloides and Alnus incana, which is almost a tree in these stands. The stands have a very diverse understory, dominated by Betula nana at 10-20% cover, but which also includes Ribes species, Rosa woodsii, Cornus sericea (= Cornus stolonifera), and Salix species. The shrub understory is patchy, interrupted by small Deschampsia caespitosa or Carex openings, streams, and occasional bogs. Occasionally, individuals of Picea engelmannii or Juniperus scopulorum can be found, but these are both rare. Forbs, including Corydalis caseana, Urtica dioica, Dicentra cucullaria, Aquilegia, Caltha, and Ranunculus species, are important in patches under the shrubs.
