CEGL007334 Platanus occidentalis - Acer saccharinum - Juglans nigra - Ulmus rubra Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: American Sycamore - Silver Maple - Black Walnut - Slippery Elm Floodplain Forest
Colloquial Name: Sycamore - Silver Maple Calcareous Floodplain Forest
Hierarchy Level: Association
Type Concept: This sycamore - silver maple floodplain forest occurs along riverfronts in calcareous areas of the east-central United States, including forests along small streams. Stands are dominated by Platanus occidentalis, with a mixture of other species, including Acer negundo, Acer saccharinum, Fraxinus americana, Fraxinus pennsylvanica, Juglans nigra, Ulmus americana, and Ulmus rubra. Shrubs include Asimina triloba and Lindera benzoin. Vines may be abundant, including Parthenocissus quinquefolia and Toxicodendron radicans. Herbaceous species include Arisaema triphyllum, Asarum canadense, Boehmeria cylindrica, Elymus virginicus, Pilea pumila, Polygonum virginianum, and others.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This type could be in Illinois and Missouri. It is not well characterized yet and may be difficult to distinguish from other floodplain forests where Platanus is conspicuous without being dominant. For example, see ~Acer saccharinum - Fraxinus pennsylvanica - Ulmus americana Floodplain Forest (CEGL002586)$$, ~Fraxinus pennsylvanica - Celtis spp. - Quercus spp. - Platanus occidentalis Floodplain Forest (CEGL002410)$$, ~Fraxinus pennsylvanica - Ulmus americana - Celtis laevigata / Ilex decidua Floodplain Forest (CEGL002427)$$, and ~Fraxinus pennsylvanica - Ulmus spp. - Celtis occidentalis Floodplain Forest (CEGL002014)$$. It is possible that CEGL002410 could be merged with this type, depending on level of dominance required for Platanus. Related vegetation in Virginia is treated as ~Platanus occidentalis - Acer negundo - Juglans nigra / Asimina triloba / Mertensia virginica Floodplain Forest (CEGL004073)$$.

Floristics: Stands are dominated by Platanus occidentalis, with a mixture of other species, including Acer negundo, Acer saccharinum, Fraxinus americana, Fraxinus pennsylvanica, Juglans nigra, Ulmus americana, and Ulmus rubra. Shrubs include Asimina triloba and Lindera benzoin. Vines may be abundant, including Parthenocissus quinquefolia and Toxicodendron radicans. Herbaceous species include Arisaema triphyllum, Asarum canadense, Boehmeria cylindrica, Elymus virginicus, Pilea pumila, Polygonum virginianum, and others (Van Kley et al. 1995, Weakley et al. 1998). Acer saccharinum may be a differential species in relation to some of the other associations in this alliance, as it is apparently absent from the southeastern Atlantic Coastal Plain and at the edge of its range in the southern Piedmont.
Dynamics: No Data Available
Environmental Description: This association occurs along riverfronts in calcareous areas, including forests along small streams (Weakley et al. 1998). The creation in 2000 of ~Platanus occidentalis - Celtis laevigata - Liriodendron tulipifera / Lindera benzoin - Arundinaria gigantea / Amphicarpaea bracteata Floodplain Forest (CEGL008429)$$ may dictate that the use of this type (CEGL007334), at least in their range of overlap, would be more appropriate for large rivers rather than "small streams."
Geographic Range: This association occurs on river and large stream floodplains in calcareous areas of the east-central United States from Indiana and Kentucky and possibly Ohio, south to Tennessee. Range extent may be approximately 300,000 square km.
