Summary
Grizzly bear (Ursus arctos horribilis) attacks in North American national parks injured 77 people. Most incidents occurred in U.S. parks, with an overall injury rate of 1 per 2 million visitors.
Area of Science:
- Wildlife biology
- Human-wildlife conflict studies
- Ecology
Background:
- Grizzly bear (Ursus arctos horribilis) encounters with humans in national parks can lead to injuries.
- Understanding attack patterns is crucial for visitor safety and wildlife management.
Purpose of the Study:
- To analyze the frequency and distribution of grizzly bear attacks resulting in human injury within North American national parks.
- To establish an injury rate per visitor to assess the overall risk.
Main Methods:
- Review of documented grizzly bear attacks causing human injury in U.S. and Canadian national parks.
- Data compilation on the number of attacks, injured persons, and park locations.
- Calculation of injury rates based on visitor numbers.
Main Results:
- A total of 77 injuries from grizzly bear attacks were recorded.
- 57 attacks causing 61 injuries occurred in three U.S. national parks, representing 79% of all injuries.
- 16 injuries occurred in four Canadian national parks.
Conclusions:
- Grizzly bear attacks on humans in national parks are infrequent, with a low overall injury rate.
- The majority of recorded injuries occurred within U.S. national parks, suggesting potential regional differences in human-bear interactions or reporting.
