"Livestock prefer the foliage and stems of tuliptree over those of other tree species. Young trees are often heavily browsed, and seedlings are frequently eliminated by browsing or trampling. Cattle or other browsers create "browse lines" on older trees.
White-tailed deer browse tuliptree during all seasons. Northern bobwhites, purple finches, cottontails, red squirrels, gray squirrels, and white-footed mice consume the samaras. Yellow-bellied sapsuckers use the phloem, and ruby-throated hummingbirds consume nectar from the flowers.
Tuliptrees in various stages of growth provide hiding and thermal cover for white-tailed deer, small mammals, upland game birds, waterfowl, and nongame birds. They provide habitat for the endangered red-cockaded woodpecker." 
"Tuliptree has been valued as an ornamental since 1663. The tuliplike flowers and leaves are aesthetically pleasing. The flowers are also valuable nectar producers. The flowers from a 20-year-old tree produce enough nectar to yield 4 pounds (1.8 kg) of honey.
Tuliptree was used medicinally in the late 1800's: a heart stimulant was extracted from the inner bark of the root, and a tonic for treating rheumatism and dyspepsia was extracted from stem bark ." 
"Tuliptree wood is used for construction grade lumber and plywood . It has straight grain, little shrinkage, and excellent gluing qualities. In the past is was used for carriage bodies, shingles, saddle frames, and interior finish wood. It is currently used for cabinets, veneer, furniture, and pulp. Tuliptree has only fair value as a fuelwood but good value as kindling."
