Swamps in Dwarf Fortress
Swamps suffer much of the same problems as marshes. Generally the water table is too high, resulting in an aquifer at or near ground level. Carving out a fort becomes difficult and most rock will need to be imported in the form of blocks at embarkation or from the periodic traders that visit. Surface water is arguably slightly more common than in marsh biomes.
Saltwater marshes tend to lack drinkable water; it will be more difficult to survive.
All swamps and marshes, whether fresh or salt water, contain willow, with the exception of mangrove swamps, which, not surprisingly, contain mangrove trees.
