Puccinellia nuttalliana Intermittently Flooded Herbaceous Alliance

Plant associations within this alliance are found in saline flats at lower to moderate elevations in the western United States. This alliance is known from salt flats in a large, high-elevation (2900 m) park in the Colorado Rocky Mountains, and possibly in basins (1500 m) in Nevada and South Dakota. Topography is generally flat with poor drainage. Soil moisture is augmented in some areas by groundwater. There is a small microtopography of hummocks which affects the water relations and therefore species composition. The soils are moist, saline and alkaline, derived from calcareous shales. The rain- and groundwater-saturated soils usually dry out during the growing season. These communities form a ring just above the succulent plant associations associated with playas, salt flats, and saline lakes. Puccinellia nuttalliana dominates the graminoid stratum with up to 65% cover. Distichlis spicata or Hordeum jubatum often codominate the graminoid layer. The forb layer is relatively sparse, typically only 30%. It can be composed of Salicornia rubra or Triglochin maritima. |

Ledum glandulosum / Darlingtonia californica / Sphagnum spp. Shrubland

This early-seral association occurs in open mire complexes on floating lake mats and on sandy soils with perched water tables. It is restricted to the central and southern coast of Oregon. Circular or elliptical hummocks 1-3 feet taller than the surrounding mire surface form islands of ombrotrophic vegetation in otherwise minerotrophic mire fed by springs, runoff, or lakewater. Vegetation is similar to Ledum glandulosum / Carex obnupta / Sphagnum spp. Shrubland (CEGL003434), but Darlingtonia californica dominates the herb layer with up to 20% cover, and Carex obnupta is absent. Mature trees are scarce, and reproducing Pinus contorta var. contorta, Tsuga heterophylla, Thuja plicata, and Picea sitchensis are scarce or absent. These trees are slow-growing and stunted, and most die before maturity. The shrub layer is dominated by Ledum glandulosum with 10-60% cover. Vaccinium oxycoccos and Vaccinium uliginosum may be codominant, with up to 40 and 70% cover, respectively. Lesser amounts of Spiraea douglasii and Lonicera involucrata are also present. Two distinct variants occur with either Sphagnum palustre or Sphagnum fuscum dominant in the moss layer. The herb layer in the Sphagnum palustre variant is moderately diverse (up to 16 species), including more hydrophytic species such as Comarum palustre, Carex aquatilis var. dives, and Carex cusickii. The herb layer in the Sphagnum fuscum variant is depauperate and includes only 8 species, has fewer hydrophytic species, and the vegetation is conspicuously dwarfed. These conditions are caused by high acidity and low nutrient status engendered by Sphagnum fuscum. This variant does not form until the underlying peat mat is dense, firm, and sufficiently raised above the groundwater. Hollows between hummocks in both variants are generally wet, species-poor, and consist almost entirely of lawns of Sphagnum angustifolium, Sphagnum pacificum, or bare muddy bottoms if trailed by elk and deer. |

Pinus glabra - Quercus (laurifolia, michauxii, nigra) Temporarily Flooded Forest Alliance

Vegetation in this alliance occurs on natural levees and on infrequently flooded flats in floodplains of Coastal Plain streams, both blackwater and brownwater, from South Carolina south to Florida, and west to Mississippi and possibly to eastern Louisiana. Pinus glabra and sometimes also Pinus taeda are typically mixed with Quercus laurifolia, Quercus phellos, Liquidambar styraciflua, Quercus nigra, and Quercus michauxii. Carpinus caroliniana ssp. caroliniana typically forms a prominent subcanopy stratum. In Mississippi, Sabal minor may be common in some examples. Shrubs may include Hypericum galioides, Hypericum hypericoides, Sebastiania fruticosa, Leucothoe racemosa, Cyrilla racemiflora, Styrax americanus, Crataegus marshallii, and Rhododendron canescens. Vines include Berchemia scandens and Vitis rotundifolia. Herbs may include Chasmanthium laxum, Saccharum baldwinii, Carex joorii, Osmunda cinnamomea, and Mitchella repens. In Louisiana, small, relatively pure stands of Pinus glabra can occur as a natural or artificial small-scale successional type, found in 'slashes' in flatwoods. |
