Wildlife Benefits:
Northern Red Oak acorns are an important food source for many birds and mammals. Other parts of this tree are eaten by various mammals (Dried leaves, saplings and young shoots eaten by deer, twigs eaten by rabbits and beavers, and bark eaten by porcupine). Trees offer habitat, cover, nesting sites, cavities, and protection for a variety of wildlife. Birds and mammals use twigs and leaves in nest construction, and may perch on the branches. Since leaves can persist more than many other plant species in some areas, young oaks may provide brushy winter cover. These persisting leaves are used by some insects to lay their eggs. Catkins can attract pollinators in the spring. Larval host that supports 557 species of caterpillars.
