Beavers in Ohio are Gnawing Their Way Back
Once nearly wiped out from Ohio due to overtrapping in the 1800s, beavers are now reclaiming their role as essential architects of the state’s ecosystems. Known for their iconic dams and industrious nature, these resilient rodents are making a “dam” impressive comeback—and the environment is better for it.
Nature’s Unsung Heroes
Beavers may not get as much attention as wolves or bears, but their impact on the environment is just as profound. With waterproof fur, webbed feet, and ever-growing iron-rich teeth, beavers are built for life in and around water. Their dam-building behavior creates wetland habitats that support a wide array of plant and animal life, earning them the title of keystone species.
“They’re what we call a keystone species,” explains Karen Lakus, lead Naturalist at the Rocky River Nature Center. “They create, modify, and maintain habitats, which benefits biodiversity across the board.”
From Extirpation to Restoration
Beavers were declared extirpated (locally extinct) in Ohio by 1830 due to the high demand for their pelts in the fur trade. But their return began in the 1930s, and now, nearly a century later, their population has rebounded significantly. The Ohio Department of Natural Resources (ODNR) estimates there are around 30,000 beavers living in Ohio today.
Wildlife officials, like ODNR Officer Mike Greer, continue to balance population management with conservation efforts. Regulated trapping is allowed, but closely monitored to ensure long-term sustainability.
More Than Just Dams
Beaver dams are built to create deep, protected ponds that serve as safe zones from predators. These structures also slow water flow, reduce erosion, and recharge groundwater. The wetlands they form support countless species of birds, fish, amphibians, and plants.
However, not all beaver engineering is welcome. When dams flood roads, farmland, or other human infrastructure, conflicts arise. Still, Lakus encourages a shift in perspective: “Wildlife will instinctively maintain their behaviors. It’s up to us, as humans, to adapt and find coexistence strategies.”
Home, Sweet Lodge
In addition to dams, beavers build lodges—domed structures with underwater entrances designed for warmth, safety, and year-round living. These lodges often house entire beaver families and are stocked with nearby food caches to last through winter.
Want to See a Beaver in Action?
Your best bet might be Beaver Marsh in Cuyahoga Valley National Park, a beloved spot for wildlife viewing. Visit around dawn or dusk for the highest chance of spotting one of these elusive ecosystem engineers at work.
As beavers reclaim their place in Ohio’s wild landscapes, they bring with them an incredible ability to heal and restore the land. Their return is a powerful reminder that with patience and protection, nature often finds a way back.
Take Action for Ohio’s Wildlife
Beavers and other wild animals still face threats from outdated wildlife practices. Speak out against cruel wildlife killing contests that target species essential to ecosystem health. Urge lawmakers to ban wildlife killing contests in Ohio. These contests are not based on science and undermine efforts to foster biodiversity in Ohio. Your voice can help protect species like the beaver and ensure a more compassionate, science-based approach to wildlife management.
