New Jersey’s 207 porcupine records belong almost entirely to the state’s forested northwest corner. Sussex, Warren, and Passaic counties hold nearly all of them, and the named places read like a tour of the Highlands and the Delaware ridge country: Delaware Water Gap National Recreation Area, Stokes State Forest, High Point State Park, Wawayanda State Park, and the Appalachian National Scenic Trail threading through them.
A bark-feeder in the ridge forest
A porcupine is a slow, deliberate climber that lives on plant material other animals ignore. Through winter it feeds heavily on the inner bark of trees, with a strong liking for hemlock, and girdled patches high in the canopy often give its presence away; in the growing season it shifts to leaves, twigs, and low green plants. The rocky ledges and dense hemlock stands of the state’s northern forests also supply the dens it returns to day after day, each one marked by a pile of droppings at the entrance.
Out in every month
Porcupines do not hibernate, and New Jersey reports appear in every season, cresting in May and June when the animals wander more widely for fresh growth and the salt they seek along roadsides. The species is near the southern edge of its eastern range here, which is why the state’s record stops at the Highlands rather than reaching the Pine Barrens or the shore.
Status in New Jersey
The porcupine is native to New Jersey and is not listed as nonindigenous by USGS NAS. It is not specifically listed under the state’s conservation framework, and the IUCN ranks it Least Concern globally, a secure species holding a narrow foothold at the edge of its range.
