CEGL007281 Robinia pseudoacacia - Celtis occidentalis - (Fraxinus americana, Liriodendron tulipifera) Ruderal Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Black Locust - Common Hackberry - (White Ash, Tuliptree) Ruderal Forest
Colloquial Name: Ruderal Black Locust Calcareous Forest
Hierarchy Level: Association
Type Concept: A dry-mesic to mesic successional slope forest of the Ridge and Valley, with Robinia pseudoacacia (up to 50%) and Celtis occidentalis (5-50%) making up most of the total canopy cover; Fraxinus americana or Liriodendron tulipifera may contribute 1-75% of the total canopy cover. Other common canopy species are Acer saccharum and Ulmus rubra. The subcanopy is typically dominated by Acer saccharum and Asimina triloba. This differs from the Ruderal Black Locust Forest (CEGL007279) in having a more mixed canopy, in occurring over calcareous substrates, and in having calciphilic species. This successional forest is found on calcareous shale ridges and knobs, and at least some stands are thought to have resulted from clearcutting.

Classification Comments: This association is described from Tellico Pilot Project (Ridge and Valley of Tennessee, northeastern Monroe County; 43 stands sampled), where this successional forest is found on calcareous shale ridges and knobs, and at least some stands are thought to have resulted from clearcutting (Andreu and Tukman 1995).
