Shagbark hickory (Carya ovata) is a powerhouse wildlife tree in southern New England’s richer upland forests, river terraces, and  rocky slopes, where its sweet nuts function as high‑calorie currency in the autumn food economy. The thick‑shelled hickory nuts  are relished by gray and red squirrels, flying squirrels, chipmunks, white‑footed mice, foxes, black bear, wild turkey, wood duck,  and mallard, with squirrels in particular caching and dispersing seeds across the landscape. Its buds and twigs are browsed by  deer, and the deep, resilient root system anchors soils on slopes and ledges that also serve as travel corridors and denning sites  for a variety of mammals. 

The shaggy, curling bark plates create unique vertical habitat: brown creepers and other small birds tuck nests behind the loose  bark, while several bat species in the region use the warm, protected bark shelters as summer roosts, making mature trees  especially valuable. As a host for numerous moth and butterfly larvae—as well as walking sticks and other insects—it converts its  foliage into protein that fuels insectivorous songbirds during the breeding season and migration. Long‑lived individuals, often two  to three centuries old, function as enduring habitat structures in oak–hickory and transition forests, combining mast production,  specialized bark shelter, and complex canopy architecture in a single, irreplaceable tree.
