• Quite common in most of its range.

• Porcupines can be detrimental to nurseries but are selective in the trees they eat and generally doesn’t pose a threat to natural forest areas.

• At birth, porcupine quills are soft, but they quickly harden. This makes their greatest defense mechanism present, even for newborns.

• These large rodents can’t shoot their quills but, like hair on other mammals, some of the quills shed and may fly off when the animal is threatened and moves quickly.

• They are nearsighted, and sometimes considered dumb, but studies show that they can memorize intricate trails to good food sources.
