Deer Camp 2019: Be on the Watch for Poisonous Deer

Though they have not yet evolved in carnivorous or venomous creatures, that doesn’t mean that the whitetail deer population isn’t dangerous. No, they have not yet grown opposable thumbs, giving them the ability to shoot back, but they have developed a deadly disease known as EHD.

According to Michael Gordon of the Mossyoak.com website,  signs of infection are highly variable and many infected deer appear normal or show only mild signs of illness. When illness occurs, signs and lesions change as the disease progresses.

The animals are affected by the onset of a feverish and depressed state, swollen head, neck, tongue or eyelids and difficulty breathing. Deer usually die in one to three days from a severe infection. Some survive longer, becoming lame and lose their appetite while others may become disabled for weeks or months by lameness and emaciation.

The development of different lesions as progression occurs has led to the categorization of 3 forms of hemorrhagic disease: Peracute, Acute, Chronic.

PERACUTE

A very rapid form shows only severe fluid swelling (edema) of the head, neck, tongue, eyelids and lungs in animals living somewhat longer.

ACUTE

A “classic hemorrhagic” form occurs. These animals may have edema in the same locations as Peracute but also have hemorrhages or congestion in the heart, pulmonary artery and oral mucosa, with some having erosions or ulcerations on the dental pad, tongue, palate and rumen.

CHRONIC

The chronic form is signified by growth interruptions of the hooves and possible sloughing of the roof walls. Other chronic lesions include: oral ulcerations, Papillae loss and scarring of rumen mucosa.

But also note not all of the above lesions will be found in an individual deer. Other diseases also produce similar hemorrhagic and ulcerative lesions. Dead whitetail are often found in or near water. The high fever and edema causes an unusual thirst and deer seek water and often die there.

WHEN DOES IT OCCUR?

EHD occurs when there seems to be an abundance of the culicoides insect. These tiny biting flies are the culprit for spreading the disease. The males and females both survive by eating nectar from flowers but only the female needs to eat blood for the maturation of fertilized eggs. Females typically deed at dusk or dawn often in large swarms in the vicinity of water, marshes or rotting vegetation. The females then proceed to lay their eggs en masse in habitat ranging from water vegetation, slow running streams, damp soil and manure heaps.

Nature seems to provide the conditions for the outbreaks of biting flies. Man has tried to control them but has failed. Nature provides a kill switch that occurs after the first frost. All the biting flies die off and so do the EHD outbreaks within a few weeks.

IMPACT ON DEER POPULATION

The severity and distribution of hemorrhagic diseases are highly variable. Past occurrences have ranged from a few scattered mild cases to dramatic outbreaks.

Death losses during outbreaks usually are well below 25 percent, but in a few instances have been 50 percent or more. To date, repeated outbreaks have not represented a limiting factor to deer population and growth. There is little evidence to suggest that outbreak severity is related to population density.

HD is the most important viral disease of whitetail deer in the U.S. and occurs over a large part of the country. Although the frequency and severity of outbreaks vary regionally.

The disease is caused by related orbiviruses in the epizootic hemorrhagic disease  (EHD) and blue tongue (BT) virus serogroups. Because clinical disease produced by EHD and BT viruses is indistinguishable, the general term “HD” (hemorrhagic disease) often is used when the specific virus is unknown. The EHD and BT viruses are transmitted by biting flies and HD occurs seasonally in late summer and early fall and then quickly ends after a killing frost.

DIAGNOSIS

So what I’ve gathered here is that the virus is spread by a biting midge that breeds in stagnant and warm waters after a drought or prolonged warm spell. The insects emerge and bite the whitetail and the virus is spread by a female midge biting a whitetail that has been infected and so passes it on to the new host.

The virus is not always fatal but has a very high mortality rate. Some animals eventually build up a resistance and some do not. The EHD is not transferable to humans and the meat is safe to eat. Livestock can also be infected and the disease may be spread from flies that were incubated in manure piles and cattle watering holes.

Although it seems that Ohio’s deer herd could be doomed, EHD has been here before and always dies out in the winter.

At present, there are no wildlife management tools or strategies available to prevent or control HD. Although die-offs of whitetail often cause alarm, past experience has shown mortality will not decimate local deer populations and that the outbreak will be controlled by the onset of cold weather.

There’s even a video out there of a deer suffering from this disease that drowns itself in chest deep water, not even bothering to swim or turn and exit the stream it had wandered into. If you see deer acting strangely this season, put them down and leave them. It’s better not to risk eating a diseased deer. It’s not like the herd is sparse. Make sure you adhere to local and federal law when hunting and let a DNR specialist know if you have any concerns.

HERE ARE THE 3 BEST BUYS AT RDDUSA RIGHT NOW

Summertime

Now that the warm weather is officially here, it is time to get ready for hiking, camping, military tenting, fishing, frolicking, and family. I took a trip to one of the Goose Mountain type stores the other day and was astonished to learn that apart from a few read-headed stepchild brand of clothing items, if I wanted to buy anything from there I was going to have to take a mortgage out on the farm in order to do so. Apart from the ambiance of the place in the form of stuffed bears and moose heads adorning every wall, I wasn’t really impressed with the quality of the merchandise per se… for you see, I have always had this proclivity to hurt people and destroy things. Even before I decided to do such as a means of support for myself, I was able to destroy an anvil with a rubber mallet, (easily done if you set the mallet on fire and melt it over the anvil). So my point is that I am hard on equipment. I checked the soft thin fabric of one of the name brand tents that was on sale and could just picture what only a few floating embers from the fire would do to such a dainty means of shelter. I quickly went home and looked up my favorite military surplus site, and here is what I found to be a great deal right now.

    1. Packs. Let’s face it, you can’t do any sort of camping, fishing, or foraying without a pack to carry your stuff in, (or out for that matter). And the good news is that RDDUSA has a great assortment of packs that have helped several different armies win wars over the years. These things are well built and easily cared for. They are also rugged.
    2. Clothes. This isn’t the thin fashionable stuff that you will see presented sweetly on a svelt and thin limbed European mannikin at Macy’s, this is rugged wear at it’s finest.
    3. Military surplus tents. These things will shake off the swirling embers of your bonfire like cattail down scattered in a summer’s breeze. definitely not the dainty fabrics that dreams are made of, this heavy canvas duck will withstand hurricane winds in some instances, and will make you stronger in the process.
