Scarlet Oak
(Wide & Flat: Alternate Arrangement)

A medium to large sized tree to 75', of dry upland sites and many parks and streets. Drooping dead lower branches persist on the tree for many years. The acorns are important food for many mammals and larger birds. Fungus often infects Scarlet oaks as they reach medium size, rotting the wood.
