American Sycamore

Platanus occidentalis

American sycamore is a common sight on the Reservation, particularly along riparian zones and wetlands. On older branches/trunks, the outer bark peels away and reveals its characteristic stark-white inner bark. Speaking of inner bark, the heartwood within P. occidentalis rots quickly and creates large hollow cavities for all kinds of wildlife to take advantage of, making it quite homey for some. Furthermore, this tree is long-lived and often grows to have truly giant proportions. The largest recorded was over 170 ft. tall and around 13 ft. in diameter, though historical records suggest even larger ones existed. Heck, some were so large they were even used as temporary homes for early settlers across Appalachia.
