What is a deers lifespan?

The lifespan of a deer varies depending on the species and the environment, but on average, it ranges from 6 to 14 years.

White-tailed deer, which are found throughout North America, typically live for about 6 to 14 years in the wild. There have been records of some individuals living beyond 20 years, but these cases are uncommon. In captivity, white-tailed deer can live longer, often reaching 15 to 20 years of age.

Mule deer, another common species in North America, have similar lifespans to white-tailed deer. They typically live for about 6 to 14 years in the wild, with some individuals living slightly longer. In captivity, mule deer can also live up to 15 to 20 years.

The lifespan of other deer species, such as the red deer, roe deer, or fallow deer, can vary. Red deer, found in Europe and Asia, generally live for about 10 to 15 years in the wild. In captivity, they can live slightly longer, reaching up to 20 years.

Roe deer, which are widespread across Europe and Asia, have a shorter lifespan, usually ranging from 6 to 10 years. They rarely live beyond 12 years, even in captivity.

Fallow deer, native to Europe and introduced in other parts of the world, have a similar lifespan to roe deer, averaging about 6 to 10 years in the wild. In captivity, they can live up to 15 years.

It's important to note that various factors can impact a deer's lifespan, including nutrition, predation, habitat quality, hunting pressure, and the presence of disease, among others.
