A cypress dome is a type of swamp, typically dominated by pond cypress (''Taxodium ascendens''). The trees at the center of the swamp grow higher than the trees at the edge, which forms a dome-like shape of treetops when viewed from a distance. Cypress domes form in flatland depressions in the Gulf coastal plain and southern Atlantic coastal plain, in the states of Georgia, Florida, Alabama, Mississippi, and Louisiana.〔(【引用サイトリンク】title=Dome Swamp )〕〔(【引用サイトリンク】Southern Coastal Plain Nonriverine Cypress Dome )〕〔(【引用サイトリンク】South Florida Cypress Dome )〕 Cypress domes form when pond cypress grow in shallow standing water. The ground level in the center of the dome may be several inches to a few feet lower than at the edge of the dome, but tree growth is more vigorous at the center of the dome. Thus, the treetops are higher at the center than at the edge of the dome.〔(【引用サイトリンク】title=Types of Florida Swamps )〕〔 Cypress domes are the most common swamp habitat in Florida. Most abundant in Central Florida, they also occur in other areas of Florida above the Florida Keys. Southern coastal plain nonriverine cypress domes are found throughout the southern coastal plains. Swamp tupelo (''Nyssa biflora'') and sweetgum (''Liquidambar styraciflua'') sometimes grow along with cypress.〔 These domes can be found in Eglin Air Force Base, and in numerous preserves including Cypress Creek Preserve and Conner Preserve. In North Florida, domes can contain pondspice (''Litsea aestivalis''), panhandle spiderlily (''Hymenocallis henryae''), and small-flowered meadow beauty (''Rhexia parviflora'').〔 South Florida cypress domes are found in southern Florida, in particular in and around the Everglades and the Big Cypress National Preserve. They are distinguished from southern coastal plain cypress domes by the presence of tropical understory species.〔 These domes can have many-flowered catopsis (''Catopsis floribunda''). 〔 Dome swamps also provide breeding habitat for rare animals such as flatwoods salamanders (''Ambystoma'' spp.), white ibis (''Eudocimus albus''), and wood storks (''Mycteria americana'').〔 The University of Central Florida's literary magazine ''The Cypress Dome'' was established in 1990; a cluster of cypresses forms such a dome in the arboretum on campus. ==List of species== Plant species that occur in cypress domes include: ; Herbaceous species〔 * toothed midsorus fern (''Blechnum serrulatum'') * false nettle (''Boehmeria cylindrica'') * sawgrass (''Cladium jamaicense'') * Carolina redroot (''Lachnanthes caroliana'') * taperleaf waterhorehound (''Lycopus rubellus'') * maidencane (''Panicum hemitomon'') * knotweeds (''Polygonum'' spp.) * beaksedge (''Rhynchospora'' spp.) * lizard’s tail (''Saururus cernuus'') * cinnamon fern (''Osmunda cinnamomea'') * royal fern (''Osmunda regalis'' var.
