Antler formation is said to be the most rapid growth known in the animal kingdom, but how does a white-tailed buck get such a huge quantity of minerals from his diet and into his antlers so rapidly? They don’t, but they do. Actually, white-tailed bucks get some of the minerals needed for antler growth from their diet and the remainder of the minerals needed from their internal reserves.

Since a buck can’t get all the raw material it needs for this rapid growth of antlers from its food, the deer must borrow it from within its body. In a process similar to that of osteoporosis in humans, minerals are taken from the ribs, sternum, and skull, and redeposited in the antlers. It’s an amazing process and bone density may decrease by as much as 30 percent! It also helps explain why mature bucks can grow larger antlers. Their skeletal frame becomes larger and literally bigger bucks can store more minerals in their bones. (more…)

The Managed Lands Deer Permit (MLDP) program as developed by Texas Parks and Wildlife Department (TPWD) allows Texas landowners involved in a formal deer management program to have the state’s most flexible seasons and increased harvest opportunities. The MLDP program is incentive based and focused on habitat management. The program really is set up to help landowners manage white-tailed deer. Participation in the MLDP program requires a written Wildlife Management Plan (WMP) approved by a Texas Parks and Wildlife Department (TPWD) biologist. However, a TPWD biologist, a landowner, or a landowner’s designated agent may prepare the WMP. A WMP prepared by a landowner or an agent must be in a format approved by TPWD and submitted to TPWD for approval. Although the program seems to be set up to run with minimal paperwork, permits will not be issued unless the WMP has been approved.

There are 3 levels of MLDPs (Level 1, 2, and 3). Higher levels offer additional harvest flexibility to the landowner, but also have more stringent habitat management requirements. There is no fee or written application, other than the WMP, for the MLDP program. Landowners or their designated agents should contact their local TPWD Wildlife biologist to request permits, but don’t wait until right before deer season. New applicants should submit all required information to their local TPWD contact by August 15 if they want to receive their permits before hunting season opens.

Permits are issued by the TPWD biologists through the Texas Wildlife Information and Management System (TWIMS), a computer automated system. Permits are mailed out of Austin each year after a TPWD biologist enters or modifies a harvest recommendation in the database. By the way, permits are valid only for the specific ranch for which they were issued.

An approved WMP will include an annually updated harvest recommendation for does and/or bucks, dependant on the level of participation. The annual harvest recommendation will determine the number of permits to be issued and will establish the maximum harvest for the property. If permits are issued after the start of deer season, all deer harvested prior to permit issuance, regardless of permit level, must be counted towards the maximum quota. Subsequent survey data may indicate a need to amend the harvest recommendation, which could result in a supplemental issuance of MLDPs.

Once permits are issued, all deer harvested (with the exception of buck deer on Level 1 properties) on that property must be tagged with the appropriate MLDP. Completion of the hunting license log and use of a hunting license tag are not required for deer harvested under the authority of a MLDP, but since all deer must have the MLDP, harvest is stricly regulated and intended to meet a landowners objectives.

Providing reliable harvest data, including accurate ages as determined by tooth wear and replacement, is a requirement for program participation. A suggestion for untrained individuals is to remove and label one jawbone from every deer harvested for a wildlife biologist to age at a later date. Jawbones must be labeled in such a way that the biologist can identify the deer on the data sheet. Check this out for more information on the aging deer using the tooth wear technique.

Now, it’s time for specific information about TPWD’s MLDP program. This information is straight from TPWD’s website: (more…)

The Texas Parks and Wildlife Department will be conducting special drawings for hunts and applications for these quality, affordable hunting experiences are available online now. Application booklets are also being mailed to last year’s primary hunt applicants and will be available at TPWD law enforcement offices.

During the upcoming hunting seasons, more than 5,700 hunters will be selected through random computer drawings allowing access to some of the state’s high-quality managed wildlife habitat. Wildlife management areas, state parks and leased private property will be available for these quality supervised hunts for white-tailed deer, mule deer, pronghorn, javelina, alligator, exotics, feral hog and spring turkey.

In the US, white-tailed deer were originally transported to restore populations that were “shot out” during the early 20th century.  Today, land managers continue to move deer from one area to another, but not just to restore populations. The driving force behind today’s deer translocations is primarily twofold: to augment low-density deer populations and to promote genetic improvement. However, a third option for translocation is an alternative to harvest — to manage overabundant populations; remove deer found in high deer-density urban areas, transport them, and release them elsewhere.

But regardless of why deer are moved, how do they cope? What is the survival rate and performance of transported deer after they are “liberated” at their release site? These are good questions and a study out of Texas A&M University-Kingsville hopes to answer them. We know that for a translocation program to be successful we need two things, a high survival of released deer and for the animals to remain in the area where they were released. Without achieving these two objectives, the overall goal will not be met. (more…)

Well, it’s not a white-tailed deer and it’s not located in the US, but a yearling (1 1/2-year old) Roe Deer was spotted in Italy with only a single antler protruding from the center of it’s head! The director of the Center of Natural Sciences in Prato told the press:

“This is fantasy becoming reality. The unicorn has always been a mythological animal.”

The 1-year-old buck, who not coincidentally is nicknamed “Unicorn,” was born in captivity in the research center’s park in the Tuscan town of Prato, near Florence. Obviously, the buck was born with a genetic flaw because his twin, like other Roe bucks, has two horns.

Single-horned deer are rare but not unheard of — but even more unusual is the central positioning of the horn. The location of the horn is probably the result of trauma early in the animal’s life, but the scientific director of Rome’s zoo said:

“Generally, the horn is on one side (of the head) rather than being at the center. This looks like a complex case. This shows that even in past times, there could have been animals with this anomaly. It’s not like they dreamed it up.”

As hunters, we know how expensive it’s becoming to hunt white-tailed deer. Not only are the prices of guided hunts and hunting leases going up, but the price of raw land is rapidly rising, as well. To make matters worse, deer managers are being hit with the climbing costs of food plot seeds, supplemental feeds, and vehicle and tractor fuels.    

And as much money as the hunting industry may bring in to the US economy, it’s only a portion of the total economic impact white-tailed deer have in this country. A recent and conservative estimate put a $12.5 million price tag on deer-vehicle collisions in the state of Texas alone!

But what about crop damage? And damage to ornamental plants? And loss of human life? I understand that in many cases problems arise as people move into areas inhabited by deer. However, many suburbs create their own problems through feeding and the prohibition of hunting. But problems are problems regardless of how they come about.

We talk a lot about deer hunting and management, but let’s look at some economic aspects concerning white-tailed deer that are not related to hunting. (more…)

Antler growth in deer really is phenomenal! In fact, deer antlers are among the fastest growing tissues in the animal kingdom, growing as much as 1/2-inch per day during peak antler growth. Of course, the amount of antler material a buck grows depends upon nutrition, genetics, and age. 

Actively growing antlers are covered with a living tissue called velvet, because it really looks and feels like velvet material. During antler development, a buck’s antlers are both extremely delicate and sensitive to the touch. Even though bucks are not aggressive towards each other during the antler growing period, this is still the time when most antler damage occurs.

White-tailed deer antler growth usually begins during the month of March or April, and by August or early September antler growth has ceased. And an interesting fact: In most cases typical deer antlers begin growing out a buck’s head in a backward motion, then quickly change direction and sweep forward as we commonly know.

So how long does it take for a buck to form hardened antlers? The following photos illustrate antler growth for a single white-tailed buck in Texas from March through September. (more…)

Imagine if the Texas Legislature mandated Texas Parks and Wildlife Department write a $250 check to every person whose motor vehicle collides with a deer on a Texas public road.

We’d be talking about a lot of money. And because that money would almost certainly come from the fund holding revenue from sale of hunting and fishing license fees, the inevitable result would be crippling to TPWD’s ability to do fisheries and wildlife management and research. Those programs are almost exclusively funded from license revenue — no general tax revenue goes to Texas’ wildlife and fisheries programs.

Neither state nor local governments compile figures on how many deer/vehicle collisions occur in Texas. But the insurance industry estimates, based on claims, about 40,000 such accidents in Texas each year. (more…)
