Name:
Robinia pseudoacacia - Liriodendron tulipifera - Acer platanoides Ruderal Forest Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This ruderal forest macrogroup is found in eastern temperate North America, and shows evidence of former and heavy human disturbance, such as through plowing, grading, skidding, etc., followed by plantings, but has been allowed to succeed more-or-less spontaneously. The tree layer is dominated (>80% cover) by "weedy" or generalist native tree species, or exotic invasive tree species. The list of ruderal tree species are as follows: <u>Conifers</u>: <i>Juniperus ashei, Juniperus virginiana, Pinus rigida, Pinus strobus, Pinus virginiana</i>. <u>Hardwoods</u>: <i>Acer negundo, Acer rubrum, Amelanchier</i> spp., <i>Betula populifolia, Crataegus</i> spp., <i>Crataegus crus-galli, Crataegus mollis, Diospyros virginiana, Fraxinus americana, Gleditsia triacanthos, Gymnocladus dioicus, Juglans nigra, Liquidambar styraciflua, Liriodendron tulipifera, Malus fusca, Morus rubra, Populus tremuloides, Prunus pensylvanica</i>, and <i>Prunus serotina</i>. Naturalized exotics include the conifer <i>Pinus thunbergii</i> and hardwoods <i>Acer platanoides, Ailanthus altissima, Catalpa bignonioides, Malus</i> spp., <i>Morus alba, Paulownia tomentosa</i>, and <i>Robinia pseudoacacia</i> (although a native in the central hardwoods region, it is so widely planted outside of its range that it is essentially exotic in character). Common conifer planted tree species in old or abandoned plantations include <i>Larix decidua, Picea abies, Picea glauca, Pinus banksiana, Pinus resinosa, Pinus strobus, Pinus sylvestris</i>, and <i>Pinus virginiana</i>. In these stands, trees may still show evidence of being planted in rows and be of uniform age. Regeneration of tree species in abandoned plantations rarely consists of the current overstory. Understory shrub and herb species can be sparse in old conifer plantations, and typically are native generalists or exotics. Understory shrub and herb species in all stands vary from exotic invasives to native generalists. Invasive shrub species include a variety of honeysuckles (<i>Lonicera japonica, Lonicera morrowii, Lonicera tatarica, Lonicera x bella</i>), <i>Rhamnus cathartica</i>, and others.
