Beavers in North America: Thriving After Near-Extinction
Yes, beavers are abundant across North America. Population: 10–15 million (pre-contact: 100–400M).
Range
- All of Canada, most of US (except arid SW, FL peninsula), northern Mexico.
- Forests, wetlands, streams, ponds, lakes—anywhere with water and woody vegetation.
Ecological Keystone
- Dams: Create wetlands → biodiversity hotspots (fish, amphibians, birds, moose).
- Water regulation: Store floodwater, recharge aquifers, maintain baseflow, filter sediment.
- Fire breaks: Wet corridors slow wildfires.
History
- Fur trade (1600s–1800s) nearly exterminated them.
- Reintroduction + protection (1900s–) → remarkable recovery.
- Now managed: trapping seasons, nuisance permits, relocation programs.
Human Conflicts
Flood roads, crops, timber. Solutions: flow devices (pond levelers), culvert guards, coexistence education.
