You’ve probably seen one waddling across a suburban lawn or perched like a tiny, furry sentinel on a dirt mound by the highway. It’s a groundhog. Or maybe you call it a woodchuck. Or a whistle-pig. Whatever name you prefer, these chunky rodents are surprisingly specific about where they hang out. If you’ve ever wondered where are groundhogs found, the answer isn't just "in a hole in the ground." It's actually a fascinating look at how a species adapted perfectly to the edges of the American wilderness and the middle of our own backyards.
They are everywhere. Well, mostly.
If you're standing in the middle of a dense, old-growth forest in the deep South, you probably won't find one. If you're in the Mojave Desert, definitely not. Groundhogs are true North Americans. They don't live in Europe. They don't live in South America. They are the largest members of the squirrel family (Sciuridae) in their range, and they’ve claimed a massive chunk of the continent as their own personal playground.
The Geographic Footprint: Mapping the Whistle-Pig
So, let's get specific. Where are groundhogs found when you look at a map? They dominate the Eastern United States. We're talking from the tip of Maine all the way down to the northern parts of Georgia and Alabama. They love the Northeast and the Midwest. If you live in Ohio, Pennsylvania, or New York, you're basically living in Groundhog Central.
But it doesn't stop at the Mississippi River. They’ve pushed way out into the Great Plains. You’ll find them in Kansas, Nebraska, and even reaching into the Dakotas. Then there’s Canada. Groundhogs are tough. They handle the cold better than most of us. They are found across almost all of Southern Canada, stretching from the Atlantic coast all the way to Alaska. Yes, Alaska.
There's a weird gap, though. You won't find them in the high Rockies or the humid swamps of Florida. They like it "just right." Not too hot, not too mountainous. They prefer the transition zones.
Why the "Edge" Matters
Groundhogs are what biologists call an "edge species." They don't like the deep, dark woods because there isn't enough to eat. They don't like wide-open, barren plains because there's nowhere to hide from a hawk or a coyote. They want the best of both worlds.

You’ll find them where the forest meets the field. This is why the explosion of American suburbs was basically a giant "Welcome Home" sign for them. We cleared the thick forests, which they liked, and replaced them with grassy lawns and gardens, which they love. When you ask where are groundhogs found today, the answer is increasingly "under your neighbor's shed."
The Underground Architecture: Not Just a Hole
To understand where they are, you have to understand how they live. A groundhog isn't just popping into a random burrow for the night. They are master engineers. A single groundhog burrow can be 20 to 60 feet long. It's not just one tunnel; it's a complex network of "rooms." They have sleeping chambers, nursery chambers for the pups, and—honestly, this is the best part—dedicated bathroom chambers. They are remarkably clean animals.
They usually have multiple entrances. There’s the main hole, usually marked by a big pile of fresh dirt, and then "bolt holes." These are hidden exits, often tucked under a bush or disguised in tall grass, used for a quick getaway when a predator shows up.
Winter vs. Summer Real Estate
Groundhogs are one of the few "true" hibernators. This means their body temperature drops significantly, and their heart rate slows to a crawl. Because of this, they actually change where they are found based on the season.
- Summer Burrows: These are out in the open. Near the clover, the vegetable garden, or the lush meadow. They want easy access to food so they can get as fat as possible before the frost hits.
- Winter Burrows: When the leaves start to turn, they often move. They seek out "protected" areas. This might be a burrow dug deep into a wooded hillside or under a rock wall. The goal is to get below the frost line where the temperature stays stable.
If you see a groundhog in a wide-open field in November, it’s probably late for its nap. By then, they should be tucked away in their winter digs.
Common Misconceptions About Their Habitat
A lot of people think groundhogs are like gophers or moles. They aren't. While moles spend almost their entire lives underground eating worms, groundhogs are active on the surface. They are "diurnal," meaning they are awake during the day. This is why you see them sunning themselves on rocks or fence posts.
Another big myth? That they only live in the dirt.
Groundhogs can climb. They aren't as agile as a gray squirrel, but if there's a tasty apple tree or they need to escape a dog, they can scramble up a trunk surprisingly fast. They also swim. It’s not their favorite hobby, but they can cross small streams if they need to find better territory. So, if you’re looking for where are groundhogs found, don't just look down—occasionally look up.
The Impact of Human Development
Honestly, we've made life pretty easy for them. In the 1700s, there were likely far fewer groundhogs than there are today. The dense, unbroken forests of early America weren't great habitat. But as we cut down trees for farms and then eventually for suburban developments, we created a groundhog paradise.
They love:
- The space under decks: It’s dry, protected from the rain, and predators like foxes are hesitant to go that close to a house.
- Raised garden beds: This is basically a buffet on a pedestal for them.
- Highway embankments: The soil is usually easy to dig, and the mowed grass along the road provides a constant source of fresh greens.
This adaptability is why they are so successful. They aren't picky. As long as there is dirt deep enough to dig past the frost line and something green to eat, they'll move in.
Spotting the Signs: How to Know They’re Nearby
You might not always see the animal, but you’ll see the evidence. If you’re scouting a property and wondering if groundhogs have claimed it, look for these specific "tells."
First, look for the mounds. A groundhog entrance is usually about 10 to 12 inches wide. Unlike a molehill, which is just a small clump of dirt, a groundhog hole will have a massive "porch" of excavated soil.
Second, check the plants. Groundhogs don't nibble like rabbits. They are voracious. If your kale or marigolds look like someone took a weed-whacker to them, that’s a groundhog. They also have a habit of taking one bite out of a tomato and leaving the rest to rot on the vine, just because they can.
Third, look for "gnaw marks" on wood. They are rodents, and their teeth never stop growing. They need to chew on hard surfaces—like your porch steps or a fallen log—to keep their incisors filed down.

Managing the Relationship
Since we know where are groundhogs found—often right where we don't want them—what do you do about it?
Coexistence is usually the best path, but sometimes they threaten the structural integrity of a building. If they dig too close to a foundation, the tunnels can cause settling or water damage. In those cases, people often turn to "exclusion." This involves burying hardware cloth (a heavy-duty wire mesh) at least 12 inches deep around a structure to prevent them from digging under.
Whatever you do, don't try to "flood" a burrow. These tunnels are incredibly long and complex; you’ll just end up with a muddy yard and a very annoyed groundhog who is probably sitting in its secondary chamber, perfectly dry.
Looking Ahead: The Future of the Groundhog
As our climate shifts, the range of where groundhogs are found is creeping further north. They are being spotted more frequently in areas of Northern Canada where they were once rare. They are resilient, "generalist" eaters, and excellent at avoiding the heat.
If you want to see one in the wild, your best bet is to find a quiet meadow or an old cemetery in the late afternoon. Sit still. Watch the edges of the tall grass. Eventually, you’ll see a brownish-gray head pop up, sniff the air, and go back to the very serious business of eating clover.
Actionable Steps for Homeowners
- Identify: Ensure it’s actually a groundhog and not a badger or a muskrat. Groundhogs have bushy tails and "frosted" fur.
- Secure: If you have a shed, nail hardware cloth around the base and bury it a foot deep to prevent "new tenants" from moving in.
- Plant Smarter: If you want to keep them away from your prize roses, consider planting lavender or garlic nearby. They have sensitive noses and tend to dislike strong, pungent scents.
- Observe: If they aren't hurting anything, just watch them. They are fascinating creatures with a complex social structure and a vital role in the ecosystem (their abandoned burrows provide homes for foxes, rabbits, and owls).
Understanding the habitat and behavior of these animals helps us share the landscape a bit more effectively. They were here before the suburbs, and by the looks of it, they’ll be here for a long time to come.
