A cypress dome is a type of freshwater forested wetland, or a swamp, found in the southeastern part of the United States. They are dominated by the Taxodium spp., either the bald cypress (Taxodium distichum), or pond cypress (Taxodium ascendens). The name comes from the dome-like shape of treetops, formed by smaller trees growing on the edge where the water is shallow while taller trees grow at the center in deeper water. They usually appear as circular, but if the center is too deep, they form a “doughnut” shape when viewed from above. Cypress domes are characteristically small compared to other swamps, however they can occur at a range of sizes, dependent on the depth.
