The amount of predator and prey in an environment is usually controlled by wildlife watchers, but not always. Food might not be as available in some environments as others. This mainly depends on the amount of deer already present in the environment.
If there is a wide population of deer already congregated in one area, then there is less and less food available for new fawns. With little food to eat, the lifespan of a deer can be negatively affected. The mother of a fawn is responsible for feeding and taking care of it during its first year of life.
However, this does not always happen. The mother might be killed by predators or succumb to other elements of the wild, leaving the fawn a very slim chance at survival. Disease is a common cause for deer mortality in the wild. Some of the most common disease that kill deer in the wild are:. CWD has a nineteen percent infection rate among deer herds , primarily in male deer. This can lead to less mating and fewer fawns born.
If more than thirty percent of a herd gets infected and dies from it, then a herd will be unable to sustain themselves. EHD is significantly more contagious, with an infection rate of ninety percent primarily among white tailed deer.
Lastly, BTB is not present enough in most areas, though wildlife watchers do keep an eye out for it since it can spread to humans. Deer tend to wander onto roads that are not used as much. They get used to the roads being quiet and safe and freeze up when something dangerous starts coming their way.
Their eyes on the sides of their heads rather than the front, which makes it harder to see objects in front of them. Hunting is also a significant cause of deer mortality, particularly in male deer. For example, severe storms can cause trees to fall or forests to flood. About five percent of deer are caught beneath a fallen tree or in the midst of an intense flood. There are three basic components to managing deer herds. They are genetics, nutrition, and age.
In order to manage for older age deer herds, a manager must manipulate the herd to produce some young deer, some middle age deer, and some older age deer. Having a nutritionally healthy deer herd at or below the carrying capacity of the land usually means a highly productive deer herd. This means that excess deer need to be removed yearly in order to maintain the herd at carrying capacity and in good nutritional health. If these fawns are reared to one and one half years of age then surplus deer with the least genetic potential spikes or four points should be removed leaving the remainder to reach 5 or 6 years of age.
Remember - just because a deer is five or six does not mean it will necessarily have big antlers. The trick is to remove deer with little antler potential and save those with the best potential. Since older age does are more productive than younger age does, an older age herd produces more off spring from which to cull. However, younger does are more likely to be from the better bucks that were not removed at an early age.
Having buck to doe ratios of 1 to 1. In order to add age to a deer herd some deer need to be removed at a young age and the remainder allowed to mature.
Older age deer at maturity can then be harvested. Buck to Doe Ratios One of the ways mangers have been able to produce older age class deer is by managing for a buck to doe ratio as opposed to a more typical buck to doe ratio.
Those that survive the accidents are often left limping till their death. The chronic wasting disease is a disease that affects the neurological system. It is transmitted through saliva or other body fluids from deer. It is difficult to control and there is no known treatment for the disease. Biting flies transmit epizootic hemorrhagic disease, thereby causing extensive hemorrhaging.
Its mortality rate is high and no treatment is known for the disease. BTB is a chronic and fatal disease that affects the respiratory system. It is transmitted through the exchange of respiratory fluid, typically from sneezing or coughing. Also, there is no known treatment for the disease. He did mention of a Vermont doe that lived for 19 years. A Research result reported by the Quality Deer Management Association stated that whitetail deer living in captivity can live for up to 18 years, while quite a few have been reported to make it past two decades with some living for up to 23 years of age.
However, this is not the case for deers that are living in the wild. Deer that live in the wild are reported to have an average lifespan of four and a half years. Also, just like it is in humans and most other living species, male deer typically have a lower lifespan when compared with female deers.
Only a few male deer that lived in captivity had been reported to live for more than 15 years. Male deer in the wild live an average of about 3 years while female deer in the wild could live for up to 6. This is why deer hunters consider it a trophy when they capture a deer that is older than 3 years in age.
