Atlantic White Cedar vs Eastern Redcedar
These two species are easily confused where their ranges overlap, especially on mature trees with scalelike foliage. The two can be told apart easily by closely examining their seed cones, and also by their bark. Young trees can be readily distinguished by their foliage. Redcedar is much more common and widely adaptable; it prefers drier sites. Atlantic white cedar is limited to acidic wetlands.
