Texas Mule Deer Hunting: CWD Check Stations

Hunters than plan on mule deer hunting in West Texas should be aware of the Chronic Wasting Disease (CWD) check stations that Texas Parks and Wildlife Department (TPWD) has established for the 2013-14 season. Wildlife biologists are reminding mule deer hunters and landowners in far West Texas about the protocols developed as part the TPWD CWD management plan.

The mule deer plan includes mandatory check stations for harvested mule deer taken inside the CWD Containment Zone, which covers portions of Hudspeth, Culberson, and El Paso counties. The wildlife management plan was implemented after CWD was detected in tissue samples from two mule deer in far West Texas during the summer of 2012. Those were the first cases of CWD detected in Texas deer. Ongoing monitoring will track the spread of CWD. Continue reading

Mountain Lions and Deer Kills – Predators of Whitetail

There are many predators of the white-tailed deer, but none is as exciting or mysterious as the famed mountain lion. Mountain lions are big cats that can effectively take down any size deer, buck or doe, both sick or healthy. A mountain lion requires about 8 to 10 pounds of meat per day to survive. The lion’s diet consists of mule deer, elk, small mammals, livestock, white-tailed deer and even pets.

Generally speaking, mountain lions prefer deer. Research has found that mountain lions can kill a deer about every 9 to 14 days, but in some locations it has been found that a lion kills as many as two deer per week, especially in hot weather. This is because many other secondary predators and scavengers move into to consume what the lion has left, forcing the lion to hunt sooner than it would have consumed the kill by itself.

Mountain Lions are Predators of Deer

Source: “Once mountain lions inhabited the entire US it was believed that whitetails were a big part of their diet. Today, most mountain lions, also known as cougars or pumas, solely inhabit the Western US, where they prey upon the mule deer. However, in the Northern US and other isolated areas, mountain lion still stumble upon a few whitetails from time to time. Whitetail deer are also beginning to more westward and as a result, may become a larger part of the mountain lions diet in a few years.

Once it spots a deer, the mountain lion will quietly stalk it until it slowly closes the distance to within about 10 yards. Then, with a swift charge, it will pounce on the deer’s back, attempting to sink its sharp teeth into the deer’s neck. The weight and strength of the lion, along with the delivered wound, render the deer dead in a few minutes. Mountain lions usually attack from above in an effort to knock the deer on the ground.

Immediately after killing the deer, the lion will usually expose the guts and eat them. It will then drag the carcass to a safe hiding place where it will feed on it over the course of a few days. On average, a mountain lion needs to kill a deer every 4 to 6 days.

Although they are capable of killing the largest bucks with ease, mountain lions will usually target younger, weaker, and malnourished deer first. This helps the lion conserve its energy, especially during the winter, when energy is precious. A lion will only attack a large deer if it absolutely must.”

Mountain lions usually carry or drag their prey to a secluded area under cover to feed. As one would expect, drag marks are frequently found at fresh kill sites. Lions generally begin feeding on internal organs such as the liver, heart, and lungs first. They typically enter through the abdomen or thorax when first consuming a kill, but some feed on the neck, shoulder or hindquarters first. At many lion kills sites, the stomach of the deer will be removed and found buried nearby.

Mountain lions frequently try to cache their kill by covering it with soil, leaves, grass and sticks. Lions may eviscerate prey and cover the viscera separately from the rest of the carcass. Even where little debris is available, bits of soil, rock, grass or sticks may be found on the carcass. Mountain lions are efficient predators of deer and have no problem taking mature bucks. They are strong and can move their kills quite a substantial distance.

Impacts of Brush Management on Wildlife and Habitat

The overabundance of unwanted or undesirable brush is one of the biggest factors plagues Texas landscapes. Brush uses water, decreases grass cover and can be costly to maintain. It is, however, good for wildlife for both food and cover, but it still is only valuable in moderation. Too much of anything always becomes a problem. Property owners and habitat managers have a chance right now to enroll in the latest webinar discussing the management of brush.

Brush Management: Unintended Consequences & Habitat Management

Class Description: Since the inception of removing unwanted vegetation from rangeland there have been unplanned responses, both positive and negative. These unintended consequences have accompanied the evolution of vegetation manipulation through the eras of eradication, control, and management. Applications, as well as methodology, has had it’s surprises. The manager needs to learn from history, understand the ramifications of his actions, and to properly plan management systems.

Anthrax Detected in Exotic Antelope in Edwards County

One of the very bad diseases that impact white-tailed deer is anthrax. It tends to rear its ugly head every few years, particularly during hot, dry periods. It’s returned to the far western portion of the Edward’s Plateau. Anthrax has been detected in two sable antelopes in Edwards County, near Barksdale, Texas. This is the first confirmed anthrax case in Texas this year.

The affected premises has only exotic animals, so no domestic livestock are involved in this case. The Texas Animal Health Commission (TAHC) has issued a quarantine requiring proper disposal of carcasses before the quarantine can be released. Burning destroys the causative agent, preventing soil contamination and reducing the chances of future outbreaks. Continue reading
