There are an estimated 7,000 to 11,200 wolves in Alaska and more than 5,000 in the lower 48 states. Around the world there are an estimated 200,000 wolves in 57 countries, compared to up to 2 million before they became endangered. The wolf population has been continuously dropping since reintroduction and know there are only about 40 to 56 gray wolves in Yellowstone National Park. Height: 26-32 inches (.7-.8m) at the shoulder. Length: 4.5-6.5 feet (1.4-2m) from nose to tip of tail. Weight: 55-130 lbs (25-59 kg); Males are typically heavier and taller than the females. Lifespan: 7-8 years in the wild, but some have lived 10 years or more.
The current Whitetail deer population is estimated to be around 30 million deer in the United States. Wolves in the Great Lakes region normally consume 15-18 deer per wolf a year. There are a least 700 wolves in Wisconsin, which was estimated by the DNR. That would be 10,500 deer killed by wolves each year if they each would consume the minimum of 15 deer. There are about a total of 9,000 wolves in the United States.
Chronic Wasting Disease or otherwise known as CWD is a transmissible neurological disease of deer and elk that produces small lesions in the brain of the infected animal. It is characterized by loss of body condition, behavioral abnormalities and eventually death. CWD is classified as a transmissible spongiform encephalopathy (TSE), and is similar to mad cow disease in cattle and scrapie sheep and goat which is a deadly brain disease.
The whitetail deer is a vertebrate, which means they have an internal bone support structure. There bones are made up of living tissues that are composed of cells and red blood cells are produced in the bones. The metatarsal bones in a whitetail deer are the longest bones in the deer’s skeleton. These bones make up the deer’s lower leg. The deer's legs are perfectly designed for running and jumping. A deer walks on his toenails instead of his toes. The deer’s front legs are designed to give the deer the ability to pivot quickly and easily. The back legs give the deer running power.
If the whitetail deer is a male fawn he will grow antlers, have a dark fur, and usually have a much bigger body than a female whitetail deer. The female whitetail deer with carry the baby fawn and she will feed it to. But what the baby fawn ends up being weather a boy or girl fawn that all depends on the genes.
The whitetail deer is an amazing survivor. No matter if it is winter, spring, summer, or fall they know how to survive. There main source of survival is there fur that keeps them warm in most conditions. There second main source of survival is how fast they can run and how high the can jump. The antlers on a whitetail deer are probably one of it’s most important things that keep them alive when danger is lurking. As most people already know that male whitetail deer only usually have antlers that they use to fight other bucks or protect themselves and there family from danger. There are rare occasions were female whitetail deer have antlers but it is rarely seen. Female whitetails do try there hardest to protect there fawn, but it is usually the buck who fights the predator off if he can. They also have bed that they make in tall grass to keep them warm and for shelter.
There is a wide verity of foods that deer like to eat. Here is a list of foods they eat. acorns beechnuts hickory nuts mushrooms clover alfalfa corn winter wheat oats soybeans peas sweat potatoes apples Water Twigs Leaves Grasses Forbs (weedy plants) Fruits The animals that hunt deer are coyotes, bobcat, cougar, wolves and of course humans.
Over the years there have been more and more deer harvested, gaining more deer every year. Back in, say the 1960’s our hunting seasons did not have to much of an impact on the deer, it just keep the population at a good number. Know we still have hunting seasons, but the thing is we harvest a lot more deer. But that usually is not a problem because are deer population has grown from a little under 400,000 which is an estimiate of the deer population in 1960 all the way up to around one million.
