North Dakota Rodent Diversity: Exploring the 15 Types of Rodents Found in the State

North Dakota is a state that boasts a rich diversity of rodent species, with a stunning total of 15 types found within its borders. From the common mice and rats to the more unique creatures like kangaroo rats and muskrats, there is no shortage of furry inhabitants in this region. Mice, particularly the House Mouse, dominate the rodent population in North Dakota, while voles, similar to hamsters, prefer grasslands and open forests. Rats, including the Brown Rat, are commonly found in urban areas, but native species tend to live away from human settlements. Kangaroo rats are desert dwellers renowned for their impressive jumping ability and complex burrow systems. Squirrels, chipmunks, and ground squirrels can be found in various environments, often indulging in their favorite food, nuts. Pocket gophers are masters of camouflage, blending into their surroundings with different fur colors and carrying food in their cheek pouches. Muskrats, semiaquatic rodents, build their dens in marshes and feast on aquatic plants. The enigmatic lemmings are known for their unpredictable population shifts and their remarkable jumping behavior. Beavers, the largest rodents in North America, reshape their surroundings by building dams. Lastly, North American Porcupines may not be the best climbers, but their sharp quills serve as an effective defense mechanism. So dig into this comprehensive article to discover the fascinating world of North Dakota’s rodent diversity!


Mice are the most numerous rodents in North Dakota, with the House Mouse being the most common species. These small creatures can be found in various habitats, including homes, farms, and fields. They are known for their ability to reproduce quickly, which is why they are so abundant in North Dakota and around the world. House mice are typically gray or brown in color and have a pointed snout, large ears, and a long tail. They are excellent climbers and can easily navigate through narrow spaces. While these rodents may be a nuisance to some, they play an important role in the ecosystem as prey for predators such as owls, hawks, and snakes.


Voles, closely related to hamsters, are another common rodent species found in North Dakota. These small mammals prefer grassland or open forest habitats where they can burrow and hide. Voles play an essential role in the ecosystem by aerating the soil and controlling plant growth through their feeding habits. They primarily feed on grasses, seeds, and roots, and their presence can often be identified by the network of tunnels they create underground. Voles have short legs, small ears, and a stocky build, making them well-adapted for a life spent primarily underground.

Rats, including the Brown Rat, can be found in both urban environments and more natural areas of North Dakota. While the Brown Rat is common in cities, native rat species in the region live away from human settlements. Rats are highly adaptable and can survive in a variety of environments, making them widespread and successful. These rodents have a reputation for being scavengers and are often associated with garbage dumps and other areas where they can find food. However, they are also skilled climbers and swimmers, allowing them to access food sources in a variety of ways. In the wild, rats play an important role as prey for predators such as foxes, coyotes, and birds of prey.

Kangaroo Rats

Kangaroo Rats are unique desert-dwelling rodents known for their jumping ability and complex burrow systems. These small animals have long hind legs and a long tail, which they use for balance and propulsion when hopping. Kangaroo Rats are incredibly agile and can jump several feet in a single bound, which helps them navigate the sandy terrain of their desert habitat. Their burrows are elaborate structures that protect them from predators and provide shelter from extreme temperatures. Kangaroo Rats primarily feed on seeds, which they can store in their burrows for times when food is scarce. Their adaptations to desert life allow them to survive in harsh conditions where other mammals may struggle.

North Dakota is home to various squirrel species, including the ever-popular chipmunks. These small, nimble rodents can be found in a range of habitats, from woodlands to urban parks. Squirrels are known for their energetic and acrobatic behavior, as they can quickly and effortlessly navigate through trees and across the ground. Their diet mainly consists of nuts, which they gather and store for future consumption. Squirrels play an important role in seed dispersal by burying nuts and often forgetting where they hid them, allowing trees to regenerate and grow. While they may sometimes be seen as pests, squirrels are a charming and lively part of North Dakota’s wildlife.

Ground Squirrels

Ground squirrels are true omnivores that live in burrows in open, grassy areas. They are similar to Prairie Dogs, sharing a similar habitat and social structure. Ground squirrels have a varied diet that includes seeds, fruits, insects, and even small vertebrates. Their burrows are extensive systems that provide protection from predators and extreme weather conditions. These underground dwellings also serve as communal living spaces for ground squirrel colonies. Ground squirrels are important in maintaining healthy grassland ecosystems by aerating the soil and controlling vegetation through their foraging habits.

Pocket Gophers

Pocket gophers are small, burrowing rodents that have adapted to blend into their environment through different fur colors. They are known for their distinctive facial features, including small eyes and large, protruding incisors. Pocket gophers have specialized cheek pouches that allow them to carry food with ease as they gather and store it in their underground burrows. These burrows can be extensive and contain multiple chambers for different purposes. While pocket gophers may sometimes be considered pests due to their burrowing habits in agricultural areas, they are essential for soil aeration and plant propagation.


Muskrats are semi-aquatic rodents that build their dens in marshes and wetland habitats. These small mammals are well-adapted to life in and around water with their webbed feet and waterproof fur. Muskrats primarily feed on aquatic plants, such as cattails and water lilies, which they consume both above and below the water’s surface. They play a vital role in wetland ecosystems by helping to control plant growth and creating habitat for other species. Muskrats are known for their ability to construct impressive lodges made of mud and vegetation, providing them with shelter and protection from predators.

Lemmings are small rodents known for their erratic population shifts and unique behavior, such as their jumping ability. These creatures inhabit tundra and grassland areas and can be found in North Dakota. Lemmings play a crucial role in the Arctic food chain as a primary prey species for predators like foxes and owls. They have a cyclical population pattern, with large fluctuations in numbers between peaks and crashes. This boom-and-bust cycle is influenced by various factors, including food availability, predation, and weather conditions. Lemmings are excellent jumpers and can navigate through their habitats with ease, allowing them to escape from predators or move between different feeding areas.

North American Porcupines

North American Porcupines are unique rodents known for their defensive quills and tree-climbing abilities. These solitary animals have a stocky build and are covered in sharp, barbed quills that deter predators. When threatened, a porcupine will raise and fan out its quills, making it difficult for predators to attack. While they are adept climbers, porcupines are not the best at navigating trees and may sometimes become stranded. However, their sharp quills provide them with an effective defense mechanism against most predators. Porcupines primarily feed on tree bark, twigs, and leaves, making them an important part of North Dakota’s forest ecosystems.

In conclusion, North Dakota is home to a diverse array of rodents, each with its unique characteristics and adaptations. From the abundant House Mouse to the elusive North American Porcupine, these small creatures play vital roles in the state’s ecosystems, from seed dispersal to soil aeration. While some may consider rodents to be pests, they are an integral part of the natural world and deserve our appreciation and understanding. Whether jumping kangaroo rats in the desert or tree-climbing porcupines in the forests, rodents bring a sense of wonder and fascination to North Dakota’s wildlife.
