This forest association is currently only known from Point Reyes National Seashore in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This forest grows on the lower to middle third of moderate to steep slopes. Aspects are generally south-southeast. Soils are moderately fine sandy clay loams, sometimes derived from Franciscan Melange parent materials. This forest forms a two-tiered canopy with <i>Pseudotsuga menziesii</i> dominating the upper canopy. which is intermittent to continuous and generally more than 30 m in height. <i>Quercus agrifolia</i> or <i>Umbellularia californica</i> may dominate the lower tree canopy, though <i>Umbellularia californica</i> is not present in all stands. The shrub layer can be open to intermittent and is highly variable. <i>Corylus cornuta</i> is often present, as are <i>Toxicodendron diversilobum, Rubus ursinus</i>, and/or <i>Rubus parviflorus</i>. The herbaceous layer is open to continuous, and often contains <i>Clinopodium douglasii, Stachys ajugoides, Maianthemum stellatum, Iris douglasiana, Sanicula crassicaulis</i>, and/or <i>Erechtites minima</i>. <i>Dryopteris arguta</i> is important in some stands. |

This alliance is found in still, shallow to moderately deep water of ponds and lakes in the northwestern Great Plains. Associations occur in the permanently inundated, 'deep water' zone of glacial ponds in gentle, rolling, glacial terrain. The underlying parent material is mixed sedimentary (partly calcareous) glacial till. Pond bottoms are typically composed of mud, organic mud, or mud mixed with gravel and stones. All examples are dominated by aquatic macrophytes. ~Potamogeton richardsonii$ is the most prominent and conspicuous plant due to its broad leaves. It dominates the forb layer with up to 50% cover. Other aquatic associates can include ~Utricularia macrorhiza (= Utricularia vulgaris), Potamogeton gramineus, Ranunculus aquatilis, Myriophyllum spicatum$, and ~Polygonum amphibium$. |

This alliance encompasses much of the oak-dominated scrub communities of coarse, dry sands of Florida and is only rarely found in adjacent states. On the Gulf Coast, this alliance is especially represented where coastal terraces reach the Gulf of Mexico, with no barrier island. It includes both coastal and interior oak scrub vegetation, with scrub oaks over and among other smaller shrubs. Associations affiliated with this alliance are found in three different areas: inland on the Florida peninsula; along the Atlantic Coast of Florida; and along the Gulf Coast of Panhandle Florida and a small portion of Georgia and possibly Alabama. This includes examples which are generally referred to as 'coastal scrub' as well as those called 'Florida scrub.' Communities in this alliance generally have several scrub oak species, primarily ~Quercus geminata, Quercus myrtifolia, Quercus chapmanii$, and ~Quercus inopina$ (in Lake Wales Ridge examples). Other sclerophyllous or microphyllous shrubs are often also present, such as ~Ceratiola ericoides, Serenoa repens, Sabal etonia, Lyonia ferruginea$, and others. This phase of Florida scrub vegetation either lacks pines, or has them at very low densities. Scattered individuals of ~Pinus clausa$ or ~Pinus elliottii$ could be present. Some characteristic species in Gulf Coast examples include ~Conradina canescens, Chrysoma pauciflosculosa, Lupinus westianus, Chrysopsis gossypina ssp. cruiseana$, and ~Chrysopsis godfreyi$. The ground cover frequently includes fruticose lichens such as ~Cladonia leporina$ and ~Cladina evansii$. These may form 100% cover in some places. This alliance occurs on various kinds of deep sands; recent coastal or near-coastal dunes, or inland sand ridges and ancient dune systems. The Florida Central Ridge is composed of a variety of eolian, alluvial, and marine deposits of Miocene to early Pleistocene age. These soils are excessively well-drained Quartzipsamments which lack silt, clay, or organic matter and are very low in nutrients. While often associated with deep white sands ('sugar sands'), not all examples of scrub occur on these particular sands. It is inferred that whiter sands are associated with more ancient scrub vegetation. Early successional scrub vegetation occurs on younger, more exposed dune ridges; more protected examples may eventually develop a characteristic open pine overstory. The exposed occurrences tend to have much larger areas of open sand than do their more protected counterparts. |

This forest association is currently only known from Point Reyes National Seashore in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association grows on the middle to upper third of moderate slopes. Aspects are mostly north and east. Stands are found in the inland valleys and prefer medium to fine silt or sandy loams. This forest forms a two-tiered canopy with <i>Pseudotsuga menziesii</i> dominating the upper canopy. The top tier is intermittent, and generally less than 35 m in height. The lower tree canopy is dominated by <i>Umbellularia californica</i>, though <i>Lithocarpus densiflorus, Quercus agrifolia</i>, and/or <i>Aesculus californica</i> may provide minor cover. The shrub layer is open with only minor cover contributed by <i>Vaccinium ovatum, Frangula californica ssp. californica, Rubus ursinus</i>, and/or <i>Rubus parviflorus</i>. <i>Polystichum munitum</i> is the dominant understory species. Other common herbaceous associates may include <i>Pteridium aquilinum, Iris douglasiana</i>, and/or <i>Stachys ajugoides</i>. Generally this is a more mesic forest than ~<i>Pseudotsuga menziesii / Umbellularia californica / Frangula californica ssp. californica</i> Forest (CEGL003167)$$. It occurs on concave slopes or on more northerly aspects than that association. |

This alliance consists of evergreen shrublands of the southeastern Coastal Plain (Atlantic Coastal Plain, East and West Gulf coastal plains, and occasionally adjacent provinces). Cyrilla racemiflora, Ilex coriacea, and Cliftonia monophylla (within its range) are characteristic. Other characteristic shrubs (although some are absent in portions of the alliance's distribution) include Ilex glabra, Ilex myrtifolia, Lindera subcoriacea, Lyonia lucida, Morella cerifera (= Myrica cerifera), Morella caroliniensis (= Myrica heterophylla), Morella inodora (= Myrica inodora), Persea palustris, Smilax laurifolia, Alnus serrulata, Toxicodendron vernix, and Vaccinium formosum. In some situations, stunted Magnolia virginiana may be a component; emergent Pinus elliottii var. elliottii and/or Taxodium ascendens may be present. Communities in this alliance occur in poorly drained flats in the Outer Coastal Plain, along lake- or pondshores, where the water table is maintained in at least a seasonally saturated condition by the water body, and in seepages in rolling hill landscapes of the Coastal Plain (often associated with and adjacent to herbaceous seepage bogs). Some types occur over peats or other sapric soil types. Occurrences expand or contract in size under different fire regimes. |

Vegetation in this alliance occurs on rocky talus slopes in the alpine tundra in the Colorado Front Range. Stands are found in the lower alpine tundra close to and within the krummholz between 3300-3450 m elevation, on warm, dry microsites on stable and unstable, moving scree slopes. The ground is covered with cobbles or boulders and is nearly blown free of snow in the winter. Soils are young and poorly developed due to low soil temperature, low soil moisture during the summer, and a short growing season. ~Rubus idaeus ssp. strigosus$ is the dominant species. ~Aquilegia caerulea var. caerulea, Valeriana edulis var. edulis, Heterotheca villosa, Festuca brachyphylla$, and ~Trisetum spicatum$ are the most common forbs and, when present, occur in low abundance. Moss cover is very sparse due to the dry, rocky substrate of the alliance. |

This graminoid wetland association is the only grass-sedge wetland type in the Oregon interior valleys. It is dominated by Hordeum brachyantherum with 10-20% cover, and Carex species with 30-80% cover. Carex unilateralis is always present with cover varying from 2-60%. Other common Carex species include Carex obnupta, Carex lasiocarpa, Carex utriculata, and Carex pellita. Juncus species are also commonly present and include Juncus balticus, Juncus acuminatus, Juncus oxymeris, and Juncus tenuis. Deschampsia caespitosa is occasionally present, but never dominant. Forbs include Mentha arvensis, Prunella vulgaris, Veronica spp., and Ranunculus spp. Rosa gymnocarpa, Spiraea douglasii, Crataegus douglasii, and Salix sitchensis occasionally occur as patches in this association. With fire suppression, Fraxinus latifolia is a common native invader. In the winter and spring this association is under >10 cm of water, but it is usually dry for 3 months (July-September) each year. This association occurs on heavy clay valley deposits, often in old valley bottom river oxbows or bottomland swamp and lake remnants. |
