A long-term monitoring program is needed. Floodplain forests also tend to have a higher component of plant species that prefer these hydrologic conditions (see characteristic species above), whereas northern hardwood swamps have a higher prevalence of species preferring saturated soils such as marsh marigold (Caltha palustris), swamp raspberry (Rubus pubescens), orange jewelweed (Impatiens capensis), purple-stemmed aster (Symphyotrichum puniceum), lake sedge (Carex lacustris), blue-joint grass (Calamagrostis canadensis), and groundwater-loving species like bristle-stalked sedge (Carex leptalea), American golden saxifrage (Chrysosplenium americanum), and swamp saxifrage (Micranthes pensylvanica).
