This forest association is found at low to mid elevations of the <i>Abies grandis</i> zone, as a minor type, in northern Idaho and northwestern Montana. Stands are relatively warm and located on bottomlands, moist benches, and toeslopes with seasonally high water tables. The tree layer is codominated by <i>Abies grandis</i> and <i>Picea engelmannii</i>, with <i>Abies grandis</i> showing a greater reproductive capacity under heavy shading. <i>Pseudotsuga menziesii</i> and <i>Larix occidentalis</i> may be present on the edges or drier portions of the type. Medium-tall shrubs, such as <i>Acer glabrum</i> and <i>Menziesia ferruginea</i>, may be present but with low cover. <i>Athyrium filix-femina</i>, a fern, is usually present with greater than 50% constancy. The understory is represented by a diversity of moist-site forbs that include <i>Asarum caudatum, Clintonia uniflora, Coptis occidentalis, Galium triflorum</i>, and <i>Senecio triangularis</i>. |

This forest community type of Oregon and Washington has been sampled on the Wallowa-Whitman and Malheur national forests of the eastern Blue Mountains Ecoregion. Geomorphic surfaces are floodplains and terraces in narrow to moderately steep, moderately wide, V-, flat- and trough-shaped valleys with moderately steep sideslopes. Valley aspects range from southwest- to north- and northwest-facing. Overstory vegetation is characterized by shade-tolerant <i>Abies grandis</i>; common seral tree species include <i>Picea engelmannii, Pseudotsuga menziesii, Pinus ponderosa, Pinus contorta</i>, and <i>Populus balsamifera ssp. trichocarpa</i>. <i>Symphoricarpos albus</i> dominates the shrub layer, with <i>Ribes lacustre, Alnus incana, Acer glabrum, Rubus parviflorus, Amelanchier alnifolia, Philadelphus lewisii, Cornus sericea, Spiraea betulifolia</i>, and <i>Crataegus douglasii</i> occasionally associated. Herbaceous species commonly encountered include <i>Arnica cordata, Circaea alpina, Adenocaulon bicolor, Maianthemum stellatum, Achillea millefolium, Elymus glaucus</i>, and <i>Festuca occidentalis</i>. |

Baccharis halimifolia - Iva frutescens - Morella cerifera - (Ilex vomitoria) Shrubland

This shrubland, dominated by the nominal species, occurs in slightly elevated areas within salt flats and salt marshes as well as in marsh edges throughout much of the East Gulf, South Atlantic, and Mid-Atlantic coastal plains. This community is usually best developed at the upper limit of non-storm tidal inundation, on natural levees deposited by above-normal tides. The most common species are typically Baccharis halimifolia, Morella cerifera (= Myrica cerifera), Iva frutescens ssp. frutescens, Yucca gloriosa, Juniperus virginiana var. silicicola, Lycium carolinianum, Baccharis angustifolia, and Ilex vomitoria. Other species which may be present include Borrichia frutescens, Fimbristylis castanea, Limonium carolinianum, and Solidago sempervirens. |

Abies grandis - Tsuga heterophylla / Polystichum munitum Forest

Giant <i>Pseudotsuga menziesii</i> old-growth trees dominate the overstory of these closed-canopy, valley bottom and river terrace forests. <i>Abies grandis, Tsuga heterophylla</i>, and <i>Thuja plicata</i> are the dominant understory trees, usually with a few individuals in the canopy. Giant (>6 feet tall) <i>Polystichum munitum</i> dominate the understory, usually with over 60% cover. <i>Corylus cornuta, Oemleria cerasiformis, Taxus brevifolia</i>, and <i>Acer macrophyllum</i> can form a subcanopy in moist alluvial soils or rocky areas. <i>Vaccinium parvifolium, Mahonia nervosa (= Berberis nervosa)</i>, and <i>Gaultheria shallon</i> are occasional low shrubs, while <i>Oxalis oregana, Trillium ovatum, Maianthemum dilatatum, Rubus ursinus</i>, and <i>Prosartes smithii (= Disporum smithii)</i> are forbs which can be locally important. In seeps and wet areas along streams, <i>Adiantum pedatum</i> is found. <br><br>Both fire and flooding are important processes in these habitats, although both occur infrequently. The terraces are usually well above the river, impacted only by 100+ year flood intervals, but dependent on the deep alluvial deposits for their productivity. Most of the old-growth trees present have evident fire scars, although the presence of 100-200 year old, fire-sensitive <i>Thuja plicata, Tsuga heterophylla</i> and <i>Abies grandis</i> individuals is evidence of a fairly long fire-return interval. This type is known from medium streams to large rivers, but rarely along small or seasonal streams. |
