Plates 69-72


GIF - Palustrine System
Plate 69.--Classification: SYSTEM Palustrine, CLASS Emergent Wetland, SUBCLASS Persistent, WATER REGIME Temporarily Flooded, WATER CHEMISTRY Oligosaline, SOIL Mineral, SPECIAL MODIFIER Farmed. All natural vegetation in this wetland has been removed, and water stands in stubble from the previous year's wheat crop. (Stutsman County, North Dakota; March 1967; Photo by H. A. Kantrud)

Plate 70.--Classification: SYSTEM Palustrine, CLASS Emergent Wetland, SUBCLASS Persistent, WATER REGIME Temporarily Flooded, WATER CHEMISTRY Fresh, SOIL Mineral, SPECIAL MODIFIER Farmed. Principal plants include nut sedge (Cyperus sp.), arrow arum (Peltandra virginica), and barnyard grass (Echinochloa crusgalli). (Dade County, Florida; January 1978; Photo by P. B. Reed)

Plate 71.--Two habitats are shown here. Classification of darker zone (edge of water body): SYSTEM Palustrine, CLASS Emergent Wetland, SUBCLASS Nonpersistent, DOMINANCE TYPE Arctophila fulva, WATER REGIME Permanently Flooded, WATER CHEMISTRY Fresh. Classification of lighter zone (foreground): SYSTEM Palustrine, CLASS Emergent Wetland, SUBCLASS Persistent, DOMINANCE TYPE Carex aquatilis, WATER REGIME Seasonally Flooded, WATER CHEMISTRY Fresh. Marsh marigold (Caltha palustris) is also present in the seasonally flooded zone. This wetland lies on coastal tundra within 2 km (1.2 mi) of the Arctic Ocean.

Plate 72.--Classification: SYSTEM Palustrine, CLASS Emergent Wetland, SUBCLASS Nonpersistent, DOMINANCE TYPE Hippuris tetraphylla, WATER REGIME Permanently Flooded, WATER CHEMISTRY Fresh. A semipermanently flooded persistent-emergent wetland dominated by sedge (Carex lyngbyei) surrounds the Hippuris marsh. Burreed (Sparganium hyperboreum) grows in shallow water between the Hippuris and the sedges. (Narokachik River area, Yukon-Kuskokwim Delta, Alaska; July 1985; Photo by F. C. Golet)
