What is the lifespan of a deer?

The lifespan of a deer varies depending on the species and environment. In general, the average lifespan of a deer in the wild is 4 to 7 years. However, some species can live up to 20 years, while others may only live for 1 to 2 years. Factors that affect the lifespan of a deer include predation, hunting, disease, available food and water resources, and natural environmental factors like harsh climate conditions. Captive deer may live longer than wild deer due to reduced predation risk and access to adequate food and medical care.
