This association is only known from the Santa Monica Mountains region. This woodland association occurs on moderately steep to very steep slopes with variable aspects at low elevations between 58 and 869 m. It is dominated by <i>Quercus agrifolia</i> and <i>Juglans californica</i> in the tree layer. <i>Toxicodendron diversilobum</i> is characteristic in the understory shrub layer. A variety of grasses and forbs occur in the herbaceous layer with <i>Leymus condensatus</i> most frequently occurring. |

This association represents young, monospecific planted stands of <i>Pinus taeda</i>. Due to the commercial value of this species, this type is widely distributed across much of the southeastern United States from the Interior Highlands to the Coastal Plain, including areas outside the natural range of the species. The core concept of stands attributable to this type are those which support dense, often perfect rows of planted <i>Pinus taeda</i> or otherwise dense, young stands which are established, managed, and/or maintained for the extraction of forest products (usually pulpwood). In most cases these stands support almost no other tree species in the overstory. Understory composition and density can vary widely depending upon location, management history, and stand age. Stands are typically established with mechanical planting, but may also be established through other means. This association rarely exceeds 20-40 years of age on most timberlands. Excluded from this association are plantation stands which have "broken up" with age or thinning to approximate a more natural structure. Dense planting in rows, if successful, tends to result in nearly complete canopy closure which persists until the stand has either been regenerated or transitions into a different association. Herbaceous ground cover of any kind tends to be sparse due to reduction during site preparation, the typically dense canopy cover, and to the fact that many young plantations are infrequently burned at best. |

This generally defined association covers seasonally flooded wetland depressions, often strongly dominated by <i>Woodwardia virginica</i>, which occur in acidic sands of the Coastal Plain. Vegetation is tall, up to 1.5 m in height. Additional associates include <i>Triadenum virginicum, Carex striata, Hypericum mutilum</i>, and <i>Decodon verticillatus</i>. Woody associates typically occur at the periphery of the pond, and may include scattered and stunted individuals of <i>Acer rubrum, Pinus taeda, Liquidambar styraciflua, Clethra alnifolia, Rhododendron viscosum</i>, or <i>Vaccinium corymbosum</i>. More information is needed on this vegetation type. It is attributed to various states in the Atlantic Coastal Plain from Delaware to Florida. |

These are wet flatwoods of <i>Pinus serotina</i> with a small amount of <i>Pinus elliottii</i>. The shrubs <i>Ilex glabra, Quercus minima</i>, and <i>Quercus pumila</i> occur along with nearly complete coverage of <i>Aristida beyrichiana</i>. <i>Amphicarpum muehlenbergianum</i> is also an important grass. |
