Name:
Liriodendron tulipifera - Juglans nigra - Robinia pseudoacacia Ruderal Forest Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance includes deciduous forests dominated by <i>Gleditsia triacanthos, Juglans nigra, Liriodendron tulipifera</i>, or <i>Robinia pseudoacacia</i> primarily in areas which were once clearcut, old fields, or cleared by fire or other natural disturbances, and then planted to these species, but with no regular maintenance. Three suballiances are recognized based on dominant species: (1) <i>Liriodendron tulipifera</i> stands occur on old clearcut sites and old fields. This suballiance includes pure, often even-aged stands of <i>Liriodendron tulipifera</i>. Associated species vary with geographic location. Throughout most of the range of this suballiance <i>Acer rubrum, Robinia pseudoacacia, Betula lenta, Acer saccharum</i>, and <i>Acer negundo</i> are common components. (2) <i>Juglans nigra - Gleditsia triacanthos</i> stands are often associated with former homesites or other disturbances on fertile alluvial deposits. Associated canopy trees vary from site to site and can include <i>Liriodendron tulipifera, Juglans cinerea, Robinia pseudoacacia, Fraxinus americana, Ulmus americana, Platanus occidentalis, Acer saccharum, Acer nigrum</i>, and <i>Morus rubra</i>. The shrub layer may or may not be well-developed; common species include <i>Asimina triloba, Viburnum prunifolium, Lindera benzoin, Corylus americana</i>, and the exotic invasive <i>Rosa multiflora</i>. (3) <i>Robinia pseudoacacia</i> stands occur in pure stands or makes up the majority of the canopy. These are short-lived forests that typically result from planting or invasion following land abandonment or fire, or from other severe disturbance.
