Good habitat is important for a healthy white-tailed deer population and necessary for successful deer management. Not only does high quality habitat provide nutritious food and great cover, but good deer habitat also provides a good amount of grass, especially during the fawning season. Deer do not consume very much grass at all–it usually comprises less than 8% of their diet on an annual basis–but tall grass is very beneficial to fawns.

For white-tailed deer, fawns are typically dropped about 7 months after conception. Because the gestation period averages about 205 days in whitetail, the major fawning period is roughly 7 months after the peak of rut. Does bred early in the rut will fawn earlier and those bred late will fawn later, but the majority of deer fawns in a given area will hit the ground at approximately the same time, usually during about a two week period. Fawns, however, don’t usually get a lot of attention from hunters. And there are probably a few reasons. (more…)

Deer and deer habitat varies considerably between the northern and southern parts of the white-tailed deer’s range. In the southern U.S., starvation of deer is generally not a problem because of the mild winters that occur throughout the region. With that said, winter–especially late winter–can be a stressful time for whitetail in terms of food quantity and quality, particularly when the deer density is above the carrying capacity of the area. When it comes to winter and native deer foods, browse is the most important class of plants. Because browse plants are of utmost importance during stress periods, such as summer and winter, this article discusses habitat management activities that can increase browse production and take your native forage production and deer management program to the next level. 

As discussed here previously regarding what deer eat and their need for proper nutrition, whitetail consume a plethora of woody and herbaceous plant species. However, natural winter forage is often limited to browse, available cool season forbs, and hard mast such as acorns. During years with good mast production, deer can use this forage well into the winter. However, mast quantity can be quite variable from year to year, forcing deer to rely on alternative food sources. Cool season forb availability can also vary by latitude and can be almost non-existent in freeze-prone areas. Locations at the northern part of the whitetail’s range are typically short on cool season forbs, but so are southern areas during winters receiving low amounts of precipitation. So how can deer managers increase browse production?  (more…)

White-tailed deer, like many wildlife species, prefer habitat that is at lower successional stages. Simply stated, deer like plant communities that are dominated by plants that are considered first responders after disturbance. Any disturbance helps set back plant succession, whether it be disking established areas, clear-cutting portions of forests, or natural or prescribed fire. And although hunters understand that deer management practices are designed to improve habitat, many habitat management practices are really only designed to mimic processes that occur naturally.

Of course, when it happens naturally land managers have very little control. Such was the case last year in Texas when the almost 15,000 acre Chaparral Wildlife Management Area (WMA) unexpectedly caught fire. It was March of 2008, but because of extremely dry spring conditions, a fire that started adjacent the area burned 95% of the state-owned WMA! Anyone that knows anything about the Chaparral WMA knows that the area is representative of South Texas brushland, but active habitat and deer management practices maintain a healthy deer herd that boast some big ole whitetail bucks.

Prescribed fire is an effective management tool for deer throughout the white-tailed deer’s range because most native brush species respond well by root-sprouting, regrowing, and providing high-protein browse. You see, most plant species are well-adapted to fire, but all deer managers that use fire as a management tool prefer prescribed or controlled burning. The fire that swept across the Chaparral WMA, on the other hand, was a wildfire. And although wildfires and prescribed fires ultimately have the same impact on native plants, prescribed fires are planned and allow burners the most preparation. Prescribed fires allow landowners the ability to pre-select the areas to be burned and the conditions under which they are burned. (more…)

There are as many different kinds of food plot mixes on the market as there are days in a year, but a lot of people do not realize that the best food plots for white-tailed deer actually grow naturally! In my opinion, natural foods are the best food plots.

I guess by definition what I am writing about today can not really be considered food plots, but more like techniques to provide additional foods for deer. But I believe habitat management is the first step in deer management!

Disking- This is a simple technique that can be implemented (get it) during both the spring and fall. There is nothing magical about how disking works. The only thing necessary is that you use a disk to disturb the surface of the soil so that forb seeds can become “exposed” and germinate.

To promote warm season forbs for deer, disk the selected area before spring green-up. To promote cool season food plots simply disk the area where you would like your native food plot to be during late summer. In addition, to promote more edge and diversity you can alternate disked and undisked strips (strip disking). (more…)

When it comes to white-tailed deer management we do know a lot, but we do not know it all. There is a lot that is not known about how white-tailed deer affect their habitat under different densities with and without supplemental feed, however, that is exactly what a research project initiated on two South Texas ranchesd hoped to determine — the effects of deer on native vegetation.

To accurately conduct the research, six 200-acre enclosures were constructed on both ranches. In addition, they were divided into 3 pairs — each with target populations of 10, 25, or 40 white-tailed deer. One of each pair was supplemented with a free-choice (all you can eat) pelleted supplemental ration and the other was left to forage from only native forbs and browse. To document changes in habitat condition, canopy cover and biomass were estimated annually.

It’s almost May, so fawning season is just around the corner. And as such, today we are going to talk about providing fawning habitat. Overuse of grasslands/rangelands that are overstocked with domestic cattle on a long term basis can kill individual plants, usually grass species. This can be a huge problem for fawns. Fawns need grassy cover.

Sure, whitetail do not consume much grass — it makes up less than 10 percent of their diet and they typically on eat it at a very young growth stage — but it is important for fawn cover! Healthy ground-cover can help with fawn survival and help get more fawns recruited into the adult population. (more…)

Good habitat management is the cornerstone of a successful deer management program. But providing good habitat is more than just planting a couple food plots, setting up some protein feeders, and hoping it rains. In fact, none of that stuff is habitat management. Those things can help with available food resources, but they do little to address big issues for the plant communities found on your property.

Sure, food plots and free-choice feeders do provide supplemental food, but habitat management is a whole other issue. Habitat management is not as straight-forward as placing out food for deer to eat, so many people shy away from it. Habitat management is actively creating or restoring processes that impact habitat and food production at several levels – and they can have long-term benefits for deer rather than just over a single season or year.

As time consuming as habitat management can be, not all techniques are difficult to implement. Although I touch on different techniques from time to time, today I just want to talk about timing. Timing, as in life, really is everything! (more…)

Exotic deer were first imported into North America during the 1900’s and are now found throughout most of the white-tailed deer’s range in the United States. The number of exotics increased rapidly in the 1950’s. In Texas alone, the last exotic survey was performed in 1996 — and at that time there were an estimated 190,000 animals and 76 different species. Current estimates put the statewide number of exotic ungulates at 250,000!

Research has examined food habits of axis, sika, fallow, blackbuck antelope, and aoudad sheep — and data conclusively found that most exotics directly compete with white-tailed deer. Exotic deer, like whitetail, either preferred forbs or preferred browse, but could perform well on grass, as well. Regular readers of Buck Manager know that white-tailed deer prefer forbs when they are available, but as forbs become unavailable, they shift their diet to browse. (more…)
