The soil m usually waterlogged during the growing season, and is ofte.*' covered with as much as 6 inches of water Vegeiation includes alders, willows, but- tonbush, dogs ood]^. and swamp*pnvet. Shrub swamps occur mostly along sluggish streams and occasionally on flooj plains. They are used to s limited extent for nesting and feeding in the North and for roosting and feeding m some of the Missiasippi Alluvial Valley States. Else where, shrub swamps are little used except in a few special situations. Flywsy area: 1. Paetfle north..................... 2. Paeiie south..................... 3.

The soil is waterlogged at least to within a few inches of its surface during the growing season, and is often covered with as much as 1 foot of water. Wooded swamps occur mostly along sluggish streams, on flood plains, on flat uplands, and in very shallow lake basins. In the North, trees include tama rack, arborvitae, black spruce, balsam, red maple, and black ash. In the South, water oak, overcup oak, tupelo gum. swamp black gum, and cypress are dominant. In the Northwest, western hem lock, red alder, and willows are common. North ern evergreen swamps usually have a thick ground covering of mosses. Deciduous swamps frequently support beds of duckweeds, smart- weeds, and other herbs. Wooded swamps often occur in association with shrub swamps, and waterfowl often use the i■: ' '3' ■two types intersliAiifeably. Ia the Southeast^ Type 7 swamps become particttlariy importart ia yean when lack of suificienl fall aad early winter raias leave overflow areas dry. At such times, aooded e^.^raps reprsaent the only shallow water available over wide areas. This type is partkulariy useful to the wood duck throughout the range of this species. rtywsy sr^a Am 1.

These are often called pocoains, bays, and savannahs in the South. The soil is usually waterlogged and supports s spongy covenng of mosses. Bogs occur mostly in shallow lake basins, on flat uplands, and ^ng sluggish streams. Vegetation is woody or herbaceous, or both. Typical plants are heath shrubs, sphagnum moss, and sedges In the North, leather-leaf, Labrador-tea, cranberries, carex, and cottongrass are often present. In the South, cvrilla, persea, gordonia, sweetbay, pond pine, Virginia chainferu, and pitcher-plants are common. Scattered, often stunted, black spruce and tamarack may occur in northern bogs. Bogs have the lowest waterfowl rating, country wide, of all the 20 types. In northern New Eng land, however, they assume considerable signif icance. In Marne alone, 25,500 acres are classed as being of primary importance to waterfowl. Fly way area: Am 1. Pacific north......................................... 1, 400 2.

The soil is without standing water except after periods of heavy precipitation, but it is waterlogged to within at least a few inches of the surface during the growing season. Vegetation (often sparse or patchy) consists of salt-tolerant plants such as seabiite, saltgrass, Nevada bulrush, saltbush, and burro-weed. Type 9 wetlands occur in un drained sumps in many parts of the arid West. Sometimes they cover extensive areas. gill n Af •dl '3 I i IfM R 0 3 er> ( V 'W.- srr in mm 1-1 , r% I-, ■‘yx.
