North American Porcupine Erethizon dorsatus (Linnaeus, 1758)In need of conservation  -  S1S2 (Highly state rare)  -  Western MD only  

Status:

The presence of this species is often a surprise to Maryland residents. Porcupines are rarely encountered, but regular, in western Maryland, especially Garrett and Allegany Counties. Interstate 68 is a major barrier for the species, and many are found as roadkill on that highway.

Relationships:

Feeds on the inner bark of trees, especially Eastern Hemlock and Sugar Maple. Some large predators have learned to attack the species' belly and avoid porcupines' dangerous quills. These include the Fisher, Bobcat, and Coyote. In Maryland, vehicles on I-68 could also be listed as a major "predator".

There are 37 records in the project database.
