| Plate 12. Slightly brackish pond, cover type 1 (III-B-1) showing temporary reversal of usual spatial relationship of shallow-marsh and deep-marsh zones resulting from shallow reflooding of central bare mud flats following drought conditions. Common spikerush (Eleocharis palustris) is the dominant species in the central shallow-marsh zone, and hybrid cattail (Typha "glauca") is the dominant in the peripheral deep-marsh zone. August 4, 1961, Stutsman County, N. Dak. |
