Chamaecyparis thyoides, commonly known as Atlantic white cedar or southern white cedar, is a species of evergreen tree in the cypress family (Cupressaceae). It is native to the eastern United States, from Maine to Georgia, and can grow up to 20-30 meters tall with a trunk diameter of up to 60 centimeters.
The tree has scale-like leaves that are about 2-4 millimeters long and arranged in flattened sprays. The bark is thin, reddish-brown, and peels off in long strips. The cones are small, about 6-10 millimeters long, and have 6-10 scales.
Atlantic white cedar is a slow-growing tree that prefers moist to wet soils and can be found in swamps, bogs, and wetlands. It is an important species in these ecosystems, providing habitat for a variety of animals and helping to stabilize soil and prevent erosion.
The wood of Atlantic white cedar is highly valued for its durability and resistance to decay, and has been used for a variety of purposes including shingles, siding, fencing, and boat building. However, overharvesting and habitat loss have led to a decline in populations of this species, and it is now considered a threatened species in many areas. Conservation efforts are underway to protect and restore populations of Atlantic white cedar.
