Bayhead (original) (raw)
A bayhead or baygall is a specific type of wetland or swamp habitat. The name baygall is derived from sweetbay magnolia (Magnolia virginiana) and sweet gallberry holly (Ilex coriacea). Baygalls are recognized as a discrete ecosystem by ecologists and the swamps have been described as "distinct wetland communities in the Natural Communities of Louisiana". Baygall swamps are most often found in the low lying margins of floodplains and bottomlands with little or poor drainage to the main creek, bayou, or river channel. Baygall or bayhead swamps found on slopes and hillsides are sometimes referred to as a forest seep or hanging bogs. Hanging bogs are typically found in hardwood-pine forests. Most baygall swamps are semi-permanently saturated, or flooded.

| dbo:abstract | A bayhead or baygall is a specific type of wetland or swamp habitat. The name baygall is derived from sweetbay magnolia (Magnolia virginiana) and sweet gallberry holly (Ilex coriacea). Baygalls are recognized as a discrete ecosystem by ecologists and the swamps have been described as "distinct wetland communities in the Natural Communities of Louisiana". Baygall swamps are most often found in the low lying margins of floodplains and bottomlands with little or poor drainage to the main creek, bayou, or river channel. Baygall or bayhead swamps found on slopes and hillsides are sometimes referred to as a forest seep or hanging bogs. Hanging bogs are typically found in hardwood-pine forests. Most baygall swamps are semi-permanently saturated, or flooded. The characteristics of a bayhead swamp are mostly broad, shallow drains, which can be found near margins of bottomlands and floodplains with little or no drainage. They most often receive a slow, but steady supply of water from seepage at the base of slopes and bluffs. Baygalls are relatively shallow wetlands, ranging from wet and saturated soils and leaf litter, to a few inches of stagnate or very slowly moving water, although some may occasionally be deeper depending on topography and rainfall. Most are also under closed or nearly closed canopies. Occasionally, larger and deeper baygalls may have open water at the center with floating vegetation such as the fragrant water-lily (Nymphaea odorata). High acidity levels distinguish baygalls from other wetlands and they often support plant communities that are distinct form adjacent areas. Sphagnum is often associated with baygalls. Sometimes referred to as acid bog baygalls, baygalls typically have very low pH levels. Levels as low as 4.5 are not uncommon in the baygalls of the Big Thicket region of Southeast Texas, USA. The acidic waters that drain from baygalls can contribute significantly to blackwater rivers and creeks in the bottomlands. A baygall may be no more than a small pool or they can be a mile across. The Jack Gore Baygall Unit of the Big Thicket National Preserve at 12 square miles is said to be is the largest in the world. (en) |
