Wildlife Benefits:
Willow Oak acorns are an important food source for many birds and mammals. Trees offer habitat, cover, nesting sites, cavities, and protection for lots 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 plant that supports 557 species of caterpillars.
