Hydrology: Fed primarily by precipitation (ombrotrophic), not groundwater or streams. Water is stagnant, acidic (low pH), and low in oxygen and nutrients.
Vegetation: Dominated by Sphagnum peat moss, which further acidifies the environment. Specialized plants include carnivorous species (pitcher plants, sundews), cranberries, and stunted black spruce.
Location: Cool, boreal regions; often in glacial depressions.
Hydrology: Fed by surface water (streams, runoff, tides). Water level fluctuates seasonally; can be fresh, brackish, or saline. High nutrient and oxygen levels.
Vegetation: Dominated by emergent herbaceous plants—grasses, sedges, rushes, cattails, water lilies, pickerelweed. Few trees or shrubs.
Location: Floodplains, river deltas, lake margins, estuaries.
Hydrology: Fed by surface and groundwater; water stands for most or all of the year. Can be fresh or saltwater.
Vegetation: Dominated by woody plants—trees (cypress, tupelo, mangrove, willow) and shrubs. Understory includes ferns, mosses, liverworts.
Location: Low-lying areas near rivers, coastal plains (bayous), floodplains.
| Feature | Bog | Marsh | Swamp |
|---|---|---|---|
| Water Source | Rain (precipitation) | Surface water (streams, tides) | Surface & groundwater |
| Water Chemistry | Acidic, low nutrients | Neutral/alkaline, high nutrients | Variable, often nutrient-rich |
| Dominant Plants | Sphagnum moss, carnivorous plants | Grasses, sedges, cattails | Trees, shrubs (cypress, mangrove) |
| Typical Setting | Glacial depressions, boreal | Floodplains, deltas, shores | River corridors, coastal plains |
