Name: Acer saccharum - Juglans cinerea / Carpinus caroliniana / Matteuccia struthiopteris Forest
Reference: NatureServe Biotics 2019
Description: These rich floodplain forests are found on slightly elevated alluvial terraces of calcareous river settings in northwestern New England. They may be successional. The canopy is typically closed, and a subcanopy and/or small-tree layer is often present. Shrubs are sparse. The herb layer is very well-developed. As with most floodplain forests, the bryoid layer is essentially absent. The canopy is dominated by <i>Acer saccharum</i>, with <i>Fraxinus americana</i> sometimes abundant. Less common, but characteristic, trees are <i>Juglans cinerea, Tilia americana</i>, and <i>Carpinus caroliniana</i>. <i>Ulmus americana</i> and <i>Acer negundo</i> are often present; <i>Quercus rubra</i> may be common in better-drained soils. Vines, such as <i>Parthenocissus quinquefolia, Vitis riparia</i>, and <i>Toxicodendron radicans</i>, are sometimes common. The species-rich herb layer is dominated by <i>Matteuccia struthiopteris</i>; associates include <i>Solidago flexicaulis, Ageratina altissima, Elymus hystrix, Arisaema triphyllum, Asarum canadense, Carex sprengelii</i>, and <i>Carex hirtifolia</i>. Common and locally abundant spring ephemerals include <i>Allium tricoccum</i> and <i>Sanguinaria canadensis</i>. These forests are often invaded by exotic plants such as <i>Lysimachia nummularia, Polygonum cuspidatum, Lonicera morrowii, Rhamnus cathartica</i>, and <i>Glechoma hederacea</i>. This association is similar to ~<i>Acer saccharum - Fraxinus</i> spp. - <i>Tilia americana / Matteuccia struthiopteris - Ageratina altissima</i> Floodplain Forest (CEGL006114)$$, but is distinguished by its richer flora. Additional work may be needed to determine whether it is an earlier successional variant of that type or whether it is a distinct type found on more calcareous substrates.
