Deer Management Strategies for Burned Properties

All wildlife species need food, cover, water and space to survive. White-tailed deer are no different. Most regions of Texas have been pretty thin on food and water for wildlife this year due to pitifully low amounts of rainfall, but many properties have been impacted by wildfires too, consuming dry vegetation (food and cover) and completely setting back white-tailed deer habitat. Burned lands can look bad, real bad at first. However, the benefits of fire on native habitats have been well documented.

Fires used for habitat management purposes are always prescribed fires, not wildfires. Prescribed burns differ greatly from wildfires in that planned fires can be set to accomplish specific objectives. This is not the case with wildfires, which can also destroy homes and other valuable infrastructure. But from a habitat perspective, fire is fire. The plant communities found in Texas are well-adapted to fire. But what can properties impacted by recent wildfires expect? Continue reading “Deer Management Strategies for Burned Properties”

Deer Habitat Improvement Through Prescribed Burning, Fire

The wildfires plaguing various parts of Texas have got me thinking a lot about prescribed burning over the past few days. Prescribed burning, prescribed fire, controlled burning, or however one refers to it, is a tool used for many purposes. It is commonly used for white-tailed deer habitat improvement, but it can also be used to prevent, contain and extinguish wildfires.

In recent years, prescribed fire for range and wildlife habitat improvement has increased substantially. Granted it’s not for everyone, but many land managers understand the utility of this management cost efficient management practice (which is also a naturally occurring process).

Prescribed burning is a tool used by land managers for increasing forage quality for livestock, reducing and controlling invasive brush species and for actively managing wildlife habitat. In fact, prescribed fire can accomplish many objectives simultaneously. For example, one fire be used to reduce brush cover, eliminate fine fuel loads, increase forage quality for wild and domestic animals, and improve wildlife habitat for deer, turkey and quail. Fire sets back many woody species and eliminates fire intolerant ones such as ashe juniper (cedar).

Why Use Prescribed Fire?

Prescribed fire is used to reduce fuel loads (existing dead and dormant vegetation) and reduce the threat and severity from wildfires should one occur. Prescribed fires also reduces woody plant encroachment and are beneficial for many native plant species in a way mechanical and chemical management treatments cannot duplicate.

Wildlife, both game and nongame species, also benefit from prescribed fires which results in new plant growth and restoration of habitats which they use both for both food and cover. Benefits from prescribed fire include:

Reduce hazardous fuels, protect communities from wildfires
Reduce the spread of pests and disease
Provide habitat and forage for game and nongame species
Recycle nutrients back into the soil
Promote native species
Promote a diverse natural landscape

Prescribed Burns Often Misunderstood

Most landowners realize that not all fire is bad. Wildfires are bad when the loss of life and property are involved, but prescribed, controlled fires are not. Often times, the vegetation found on a particular property requires a managed fire, not a wildfire, to come along at the right time and under the right conditions in a controlled manner. This is prescribed burning.

Once the objectives of the fire are determined and the conditions under which the fire should be used are established, it is only then than a prescription for carrying out the fire have been developed.

The prescription should include landowner objectives, personnel requirements, firebreaks and environmental factors such as air temperature, relative humidity and wind direction and speed. The bulk of the work takes place long before the first flame hits the ground. However, proper land management after the burn is essential for both wildlife and livestock. Cattle frequently concentrate on a burn because forage is more palatable and nutritious. However, this does not mean these grass-eating machines should be released onto burn sites immediately. As with any major event, some rest is warranted afterword.

Fire is a Tool for Active Managers

As with many tools, the quality of the work depends on how good you are with the tool. Prescribed fire for brush management/control and deer habitat improvement is no different. Without a doubt, experience is the best teacher of fire behavior. Inexperienced managers can learn a lot by observing prescribed fires lit by other folks. Considerable knowledge can be learned about fire behavior relatively quickly, but it takes years of experience to get good, but even then you will not (should not) feel totally confident. Even trained professionals do not lose their fear of what fire can do.

The benefits of controlled burning for wildlife are well documented. Burning is good for deer because of the nutrient-rich browse and forbs that respond post-fire. Fire also knocks back many of the root-sprouting browse species that have outgrown the reach of deer. Fire promotes native grasses, which in turn creates better quail nesting habitat, improved water infiltration, and drought-tolerant forage. Additionally, fire is a relatively inexpensive management tool, especially for landowners interested in controlling cedar. Costs can range from $2 to $8 per acre depending on the size of the burn, prep work, and personnel needs.

To wrap up, prescribed fires have different uses depending on the objectives. The most common use of controlled burns is to reduce fuels such as pine needles, leaves and dead herbaceous vegetation such as grass and weeds. Controlled burning can also be used for brush control and quail, turkey and white-tailed deer habitat improvement. Although prescribed burning is a very effective tool, it can be incorrectly applied. Prescribed fire, just like any habitat management practice, should only be implemented once the need has been completely evaluated and deemed effective for achieving the desired objectives.

Rainfall, Habitat and Antler Growth

Managing for good white-tailed deer habitat on a property is the key to maintaining a healthy deer herd. Plain and simple, deer in good body condition are more productive than deer in poor condition. A problem many landowners face is that Mother Nature does not always do her part. This is the major reason why supplemental feeding has become an integrated part of deer management on many ranches.

A property can generally have good deer habitat, but that does not necessarily mean that the plants found on the property are in good condition. Rainfall makes a big difference from year to year. In fact, research conducted in South Texas, on what was coined the “South Texas Buck Project,” by the Caesar Kleberg Wildlife Research Institute at Texas A&M-Kingsville found that spring rains explained 70% of the year to year variability in buck antler size.

Spring rain and antler growth were highly correlated, meaning bucks grew larger antlers following wet springs and smaller antlers following dry ones. During the South Texas Buck Project, researchers classified spring rains as those occurring during March, April and May. And over much of the whitetail’s range, it is during this time of the year when good rainfall can produce bountiful crops of high protein forbs and set up browse plants for the long, hot, and typically dry summer. If the rains do not arrive, then deer can forget about the would-be protein buffet.

Okay, so I will admit that South Texas is much different than many parts of the white-tailed deer’s range, including most parts of Texas, but the results of this study are a bit staggering. The data collected during the South Texas Buck Project conclusively found that spring rains alone accounted for as much as a 20 inch shift in gross Boone and Crockett scores for mature bucks! These findings really illustrate the importance of precipitation, habitat condition and food availability to any landowner or hunter interested in deer management.

So this all makes enough sense, but how can it help hunters on their property given that they can not control the rain? Well, no one can turn on the faucet that makes it rain, but hunters can control whitetail food availability through management practices such as maintaining proper livestock grazing rates, brush management, prescribed burning, supplemental feeding and managed deer harvest. Allowing deer to grow older is one way to produce more mature bucks, but age is not the only factor that affects antler size.

In mature bucks, rainfall determines whether that 20 inch shift I mentioned previously ends up being 20 inches up or 20 inches down. Food availability is of utmost importance in allowing old bucks to reach their genetic potential. For hunters interested in trophy buck management, I would seriously considering shooting any buck 5 1/2 years of age following a wet spring. Why? For the simple reason that the chances of getting two good years in a row are slim, and therefore antlers are not likely to be better the next year. During a dry spring, such as this one, hunters may want see if those deer can add that 20 inches back on next year.

Improve Wooded Habitat for Whitetail

Hunters and landowners interested in deer management know that the bread and butter of white-tailed deer’s diet are browse plants. Although a deer would prefer to eat higher-in-protein forbs, those plants are primarily only available during the spring and fall. Though ideal deer foods consists of preferred browse plants and high protein forbs, many of these plants are not as abundant as they could be across the landscape.

Good deer habitat always has some wooded component. This woody structure provides screening shelter, overhead protection, and food from both leaves and mast. This wooded component can range from brushland to mid-story tree species to mixed forests of a variety of species. Deer habitat can vary a great deal from place to place, but too much wooded area can become a detriment to deer and the plants they eat. Proper habitat management practices, however, can make the most out of the land you hunt. Continue reading “Improve Wooded Habitat for Whitetail”

Better Fawn Survival for More Bucks

It often amazes me when I hear an uninformed hunter talk about deer management and the habitat requirements of white-tailed deer. After hearing them speak just a few sentences, it’s obvious that they do not have a clear understanding of a whitetail’s habitat needs or the foods that they eat. This blows my mind! After all, these are the same guys that proclaim to “love” hunting. But I suppose there is a big difference between deer hunting and white-tailed deer management.

Deer hunting can exist without deer management. After all, you don’t necessarily need many (or any?) deer to go deer hunting. However, white-tailed deer management can not occur without hunting as part of the overall equation. In short, you can love hunting while being indifferent to management, but if a deer management program is in place then hunting is part of the package.

So where am I going with this? I guess what I’m trying to do is illustrate is the difference between hunters that simply shoot deer and those that manage for them. There is nothing wrong with either of them. Besides, we all go through various stages in our hunting lives. However, there comes a point when most hunters connect the dots and realize that there is a strong relationship between the habitat that the land provides and the health of a local deer herd.
