Swamps Sometimes trees come to dominate swamps. Just because a tree species can live under these swampy conditions does not necessarily mean it cannot live elsewhere. Bald Cypresses does quite well under considerably drier upland conditions. Another example of swamps dominated by trees are the White Cedar swamps of the eastern seaboard of the United States from New England to the Gulf Coast. Bogs A bog is a standing body of water typically without drainage and without a source of water except drainage from the surrounding forest.
Bogs often form in the holes created by melting blocks of ice left by receding glaciers.
Bog water is typically cold, very acidic, and low in oxygen. A form of moss called sphagnum moss, over time, develops a floating mat of vegetation. This mass of vegetation can support shrubs and small trees. Within these bogs you can find tree and other plant species typical of the Northern Boreal Forest such as Black Spruce and Tamarck but found no where else in the Eastern Deciduous Forest. The vegetation of bogs, in general, is unique because of its unusual physical conditions.
