Factors Affecting Lifespan
- Predation: Predators like wolves, bears, and cougars can significantly impact deer lifespans.
- Disease: Deer are susceptible to various diseases, including chronic wasting disease, which can shorten their lifespan.
- Habitat: The availability of food and water, as well as the presence of suitable shelter, influences deer lifespan.
- Human activities: Hunting, car accidents, and habitat destruction can also affect deer lifespans.
Conclusion
The lifespan of a deer can vary significantly based on various factors. While some deer live for over a decade, others may only live for a few years due to natural or human-related threats.
