Fraxinus latifolia / Carex deweyana - Urtica dioica Forest

This mid-seral association occurs on floodplains along the middle reaches of the lower Columbia River in Oregon and Washington, and perhaps other large rivers in western Washington. It was probably widespread on bottomlands between Longview and Skamania, and may have also occurred in the Willamette Valley. Soils are hydric silt loams and are subject to extended winter flooding and midsummer drying. Topography is flat with broad depressions. Historically these sites were inundated for half the summer, but now only deeper depressions retain water until late spring or early summer. <i>Fraxinus latifolia</i> is the dominant tree, with few or no <i>Populus balsamifera ssp. trichocarpa</i> present. The herb and shrub layers are sparse and reflect the long residence time of seasonal floodwater. <i>Urtica dioica, Carex leptopoda (= Carex deweyana ssp. leptopoda)</i>, and <i>Carex obnupta</i> dominate the understory. |

This forest type is restricted to the montane zone of the Transverse and Peninsular ranges of southwestern California, from the Mt. Pinos region in Kern County, south into San Diego County. Occurrences are found from 275-2400 m elevation, usually on slopes facing the coast rather than the desert. Annual precipitation increases with elevation and ranges from 70 cm to over 100 cm, with a distinct summer dry season. Most stands are restricted to steep slopes of mesic (northern) exposures and canyon sides at lower elevations, but are found on warmer aspects at the upper elevational limits. Pseudotsuga macrocarpa is the only or dominant tree in the canopy of these stands. Other conifers that may be present include Abies concolor, Calocedrus decurrens, Pinus coulteri, Pinus lambertiana, Pinus monophylla, and Pinus ponderosa. Broad-leaved trees may also occur, including the evergreen Quercus chrysolepis and Umbellularia californica, and the deciduous Quercus kelloggii. The tree canopy is typically less than 30 m in height and is structurally composed of only one layer, with no subcanopy. Canopy cover may be continuous (on flatter sites) or intermittent (on steep slopes). Shrubs are infrequent, and the herbaceous layer is sparse. |
