(a) Source: Johnson and Temple (1980, p. 38, Table 1).
(b) Wetland classification as described in Wetlands of the United States -
Ci rcul ar 39 (FW S 1971, pp. 20 -22) :
Type 1 - Seasonal ly fl ooded basi n or fl at; soil covered w ith water or
waterlogged during variable seasonal periods but usually well
drained during much of the growing season.
Type 3 - Shallow fresh marsh; soil usually waterlogged during the growing
season, often covered with 6 inches or more of water.
Type 4 - Deep fresh marsh; soil covered with 6 inches to 3 feet or"more of
water during the growing season.
Type 5 - Open fresh water; shallow ponds and reservoirs usually less than
10 feet deep and fringed by a border of emergent vegetation.
Note: Wetland classification categories were combined in some cases because
certain wetlands were on the borderline between two types or had
characteristics of both types.
