Deer are located all over the Globe in a wide range of species and breeds and can be discovered in almost any nation or wooded area. But are you ever thought about how long deer survive? Considering how frequently deer is chased in the forest, the truth may amaze you.
We will search over how long various species and variations of deer life are, the typical deer life span, as well as the longest-living deer found in the forest in this article. You’ve arrived at the right site if you’re an activist for these life forms or certainly would like to understand more. Let’s get this discussion started.
How long does Deer Survive?
Deer live in nature for an estimated 3-6 years. Whereas other creatures make a contribution to this shorter life, human is typically responsible. This is because of prevalent predation all over the globe, along with a variety of natural conditions.
How long do captive deer live?

As stated by the Deer Association, captive deer survive considerably longer lives than deer lives in the forest. There have even been reports of wild deer living longer and healthier, raising the estimate to 7 to 10 years.
Several of the earliest deer in confinement lived for more than 20 years, with certain female deer also having given birth to fawns throughout this period. Given the major distinction in life durations of deer in the forest and deer in confinement, it’s indeed easy to assume that human as well as other wild animal interference is the cause of their reduced wild longevity.
Mule and white-tail deer, in specific, have shorter lives as a result of our elevated closeness to their natural environments. Building infrastructure and residences in deer ecosystems puts them at bigger risk and reduces their capacity to flee from wild animals.
How long do deer live in different areas?
Deer populations can differ widely from country to country. The quantity of shooting animals and the atmosphere are two factors that impact deer life expectancy in any given area.
Several of the elderly bucks discovered by research groups are in states such as Georgia and Texas. The life expectancy might be lower in those other regions where killing animals is more common. Environment and weather events can also influence the median lifespan of a deer.
The Life Span of a Deer
The typical deer life span is incredibly fascinating if the deer is conquering the wild places as a young baby deer or was born into a luxury lifestyle in confinement. Let’s get right to it.
Fawn or newborn

Baby deer, despite their cuteness and inability to defend themselves, play an important role in any group of deer. The majority of young fawns can walk within thirty min of birth, however, a mother deer would then retain her young healthy and safe in a region. Overgrown bushes and other places from where the herd has utilised their time are frequently associated.
A mother deer will nourish her kids in this shielded place for a day or two, not only to retain her baby safe and to retain the other members of the herd secure in the scenario a wild animal smells the newborn. When the baby is capable of walking and moving by itself, it will be capable of joining the herd and starting its journey as a young deer.
Young Deer

Young deer need to be fed by their mothers when they’re about five months old. They will be able to scavenge and look for food by themselves from that moment, eating leaves, vegetation, and many other herbivores.
When a deer itself has a trademark noticed coat, you understand it’s still young. This speckled presence serves as a type of disguise for young deers in natural light. This coat is still noticed till the deer comes to an end a year old. It is then regarded to be an adult.
Adult Deer

Deer are pack animals, and though their species can be quite varied, particularly as much more adult deer take part in their positions. Female adults frequently remain with the same flock and mate with the dominant bucks, whereas male deer are frequently willing to take responsibility for splitting the herd and conceivably creating trouble inside this group.
A young deer that has reached maturity has a greater likelihood of surviving. The bigger the deer, even so, ever more enticing it is to trappers as a game kill. That’s why many deer do not survive past their 1st five years in the forest.
Longevity of Various Deer Lifeforms
How long do deer live depending on the species?
Because predation has a large impact on the typical white-tail deer’s life expectancy, you could be intrigued about the life expectancy of all other deer organisms. Let’s have a look at some of these various species of deer lifespans:
- White-tailed deer have a lifespan of 3-5 years in the forest and 20 years in confinement.
- Mule deer have a lifespan of 5-9 years in the forest and 15-20 years in captivity.
- Red deer can live for 6-10 years in the forest and 20 + years in confinement.
- Sika deer can live for 10-12 years in the forest and up to 25 years of imprisonment.
- Roe deer live for 5-7 years in the forest and 10-16 years in confinement.
- Water deer can live for 7-10 years in the forest and up to 15 years in confinement.
- Eld’s deer: rare in the wild, but can live for up to 16 years of imprisonment.
- Tufted deer can live for 5-8 years in the forest and up to 15 years in confinement.
You can see that if a deer is bred in captivity, its life expectancy increases exponentially. The vast bulk of deer species, on the other side, have an abundant growing population and aren’t threatened at all.
Deer are gorgeous vicious animals to notice, regardless of species or site, in both the woods and in confinement. Their life span is unique and special, and all deer should be treated with dignity.
Factors Influencing Deer Death rates and Life expectancy
Numerous factors may influence and evaluate a deer’s life expectancy. Among these elements are:
- Homeland in the Region

Deer kept in confinement live a long life lives than in their native habitat. This is captive animals being frequently cared for and kept protected from predators. Those who inhabit the wild, on the other hand, face numerous risks.
One other thing that affects deer in the forest is deprivation. Throughout snow storms, the seas may be properly sealed and/or eroded, and during droughts, they might well be left without food for many days. These are just a few instances, however, a deer’s life in the wilderness is significantly risky and difficult, resulting in a shorter life expectancy.
- Hunting Stress
Predation is among the key contributors to the diverse range in life expectancy among natural and captive deer. According to the Whitetail Report published by the Quality Deer Management Association, predation alone kills 5.5 million deer each year. Deer don’t really survive long in areas where there is a high shooting concentration. They live much longer lives in areas with low shooting concentration.
Deer in the forest are frequently easy victims to predatory animals.
Coyotes are recognised as the reason for a substantial chunk of prey species concerns in regions all through the white-tail deer range because of their extensive dispersion. A study conducted by the U.S. Forest Service Southern Research Station at the Savannah River Site in South Carolina recorded net fawn death rates of almost 70 per cent at the location, with coyotes causing about 80 per cent of these deaths. Several good deer wild animals include mountain lions, black bears, and wildcats. The far more popular deer predator varies based on the region.
Aside from shooting animals and overhunting, auto crashes involving deer kill or injure about a million deer each year. Those who stay alive the car crashes are frequently left dragging until they die.
- Quality and amount of Animal feed
A deer’s life expectancy is also influenced by access to food. Some surroundings may not have as much food as others. This is primarily determined by the number of deer already found in the area.
When a large number of deer tend to gather in one region, there becomes less and less food available for newly born fawns. A deer’s life expectancy can be shortened if there isn’t enough food to eat.
- Relationship between Mother

The fawn’s connection with its parent influences how long it lives. Throughout its first year of life, a fawn’s mother is accountable for providing and caring for it.
This, even so, does not constantly occur. The mother may be shot dead by wild animals or capitulate towards other wild aspects, having left the fawn with a very slender likelihood of surviving.
- Severe Weather & Environment

Apart from humans who reside in houses, wild deer are willing to live outdoors if the circumstances are severe. Deer don’t really survive long in areas where severe weather events occur frequently. For instance, deer in Michigan’s upper peninsula, which experiences snow storms and hot winter weather, do not survive as long as those in south Texas, in which the temperature is mild throughout the year.
- Proximity to Highways
Every year, approximately a million deer are entangled in automobile accidents. The majority of these deer die, whereas those who are fortunate just to stay alive after the accident is wounded, making them an obvious target for wild animals or limiting their ability to hunt for food.
A bush fire is also another unanticipated threat to the safety of deer. These are prevalent in the western United States and have a devastating impact on the communities where they happen.
- Diseases
A virus outbreak can actually impact deer, just as it can people and other animals.
Chronic wasting disease (CWD), epizootic hemorrhagic disease (EHD), and bovine tuberculosis are the three most serious diseases in deer (BTB).
The neural system is harmed by chronic disease. It is transferred by deer saliva or other bodily fluids. It is harder to monitor, and no renowned therapies exist for the disease.
Biting flies spread epizootic hemorrhagic disease, causing widespread haemorrhaging. It has a high death rate, and there is no available cure. EHD outbreaks vary year to year, varying from contaminating a small proportion of the deer community to assassinating up to fifty per cent or above of them.
BTB is a fatal respiratory illness that is chronic and fatal. It is spread via the transfer of respiratory fluid, most commonly via sneezes or coughs. There is really no available cure for the illness.
Bottom Line
The largest factor that causes a variation in deer life expectancy is a deer staying in confinement vs a deer that lives outdoors.
This is due to the circumstances being dissimilar. From illness to wild animals, the forest has substantially more harmful ones to encounter and stay alive in all instances. Confinement is far more managed and dangerous, resulting in no shock that captive deer live considerably longer lives.
Due to this and other variables, the average life expectancy of a deer is unknown. It’s mostly up to uncontrollable variables, whether in the forest or in captivity.
