Yes, porcupines are Rodents. The North American porcupine is a large rodent that can be found in North America. It is second in size only to the North American beaver and can weigh up to 20 pounds (9 kilograms) and grow to be 2 to 3 feet (60 to 90 centimetres) long.
Porcupines distinguish themselves within the rodent family through their most notable feature: their quills. These are actually modified hairs coated with thick plates of keratin that are sharp enough to penetrate flesh and can be a formidable defense mechanism against predators. When threatened, porcupines raise these quills as a warning and, if necessary, will back into predators to protect themselves. Despite a common misconception, porcupines cannot “shoot” their quills; contact is required for the quills to detach.
There are around 29 species of porcupines divided into two main families: the Old World porcupines of the family Hystricidae and the New World porcupines of the family Erethizontidae. Old World porcupines are generally larger, live on the ground in the forests of Europe, Asia, and Africa, and have quills that are grouped in clusters. New World porcupines, found in North and South America, are smaller, typically arboreal (tree-dwelling), and have quills that are interspersed with bristles and underfur.
Porcupines are mostly nocturnal and have a diet consisting largely of leaves, herbs, twigs, and green plants. In the winter, they may chew on bark. They are found in various habitats, including forests, deserts, and grasslands. Their need for substantial vegetation influences their habitat choices, often leading them to inhabit areas where they can cause damage to trees and other vegetation, creating conflicts with human activities.
The quills of a porcupine are its main defense mechanism. Each quill has a barbed tip which makes it difficult and painful to remove once it has embedded into another animal. The porcupine’s quills lie flat until it is threatened, at which point they stand up as a deterrent. If the threat continues, the porcupine will often back into its aggressor, driving the quills in deeper.
In areas where human and porcupine habitats overlap, porcupines can become pests. They may damage natural timber, landscaping, and even vehicles, as they are known to gnaw on anything that has salt residue including road salt and sweaty car handles. Managing these conflicts requires responsible strategies that prioritize humane treatment, such as using fencing to protect trees and property, applying repellents, and employing live trapping followed by relocation when necessary.

Yes, porcupines are adept climbers and regularly climb trees. They use their strong claws and a prehensile tail to help them navigate and grip tree branches. Climbing trees is an essential part of their behaviour, allowing them to access food such as leaves, buds, and bark, which are significant components of their diet. Being in trees also offers them safety from some predators. Porcupines are particularly adapted to life in the trees, spending considerable time resting, foraging, and even sleeping in trees.
Porcupines defend themselves using their quills. These are sharp, barbed hairs that can easily detach and embed in the skin of any animal that comes into contact with them. When threatened, porcupines will raise their quills, making them more intimidating. They might also shake their bodies to make the quills rattle as a warning. They can strike with their tail, embedding quills in the predator if attacked.
Porcupines are known to cause significant damage to trees and vegetation due to their feeding habits. These animals primarily consume the bark of trees, a behaviour that can lead to girdling, which essentially strangles the tree and can result in the death of young trees or branches. Such damage is particularly concerning for young trees, as they are more vulnerable and less able to recover from bark loss.
In addition to bark, porcupines also feed on leaves, stems, and buds during the spring season. This diverse diet means that porcupines not only threaten the survival of individual trees but can also have broader effects on the health of entire forests. The impact is particularly pronounced in managed landscapes, such as parks and gardens, where ornamental trees are cultivated for aesthetic and ecological purposes.
Porcupines are not naturally aggressive animals. They are typically passive creatures that prefer to avoid confrontations. Their primary defense mechanism is their quills, which serve as a deterrent to potential predators. When threatened, a porcupine will turn its back, raise its quills, and may lash out with its tail. However, this behavior is a last resort; porcupines generally prefer to escape or hide rather than confront threats.
While porcupines are not aggressive, encounters can happen, especially in rural or wooded areas near Edmonton. It’s important to know how to respond if you come across one.
If you encounter a porcupine, staying calm and following these guidelines can prevent any unwanted incidents:
Keep your distance: Porcupines are curious but not hostile. If one approaches, it is likely exploring or passing by. Slowly back away without turning your back on the animal. Maintain a safe distance to avoid startling it.
Do not provoke it: Sudden movements, loud noises, or attempts to scare the porcupine may be seen as a threat. Although porcupines cannot shoot their quills, they can raise and release them upon contact. Stay still or move away slowly to reduce the chance of provoking defensive behavior.
Give it an escape route: Porcupines are non-confrontational and will retreat if given the opportunity. Make sure the animal has a clear path to leave. Avoid cornering it, as this may trigger defensive actions.
Stay calm: Porcupines move slowly and are unlikely to pursue or confront you. By remaining calm and patient, you give the porcupine the chance to move away on its own.
Avoid handling: Never attempt to pick up, touch, or corner a porcupine. Even if it seems calm, handling it may cause stress and provoke defensive reactions. Quills are painful and difficult to remove if they come into contact with skin or pets.
In most cases, if you follow these steps, the porcupine will peacefully move away, and no further action will be necessary.
During winter, porcupines do not hibernate but may reduce their activity. They seek shelter in dens, which can be in hollow trees, rock crevices, underbrush, or fallen logs. These dens protect from the elements and predators. Porcupines maintain a relatively low activity level during the cold months, primarily feeding on the inner bark of trees, as other food sources are scarce in winter. Their ability to digest cellulose helps them survive on this diet.
Porcupines are incapable of throwing their quills. This is a common misconception. When threatened, they will bristle their quills defensively, making them more prominent. If a predator directly contacts a porcupine, the quills can detach and embed in the attacker. The quills have barbed tips, making them difficult to remove once stuck into another animal or object. This passive defence mechanism is highly effective in deterring predators.
