Deer Management Through Browse Use

Browse consumption can be used for better whitetail deer management

Habitat is the cornerstone of white-tailed deer management. Plant communities, an important component of habitat, are composed of forbs, grasses, and woody plants (browse). Healthy, diverse habitat sustains native wildlife populations and almost always represent healthy deer herds. However, browsing of woody plants by white-tailed deer and domestic livestock may have negative impacts on perinneal shrubs, trees and the overall habitat.

Excessive browsing may lead to decreased plant vigor, increased susceptibility to disease, or decreased reproduction and seeding establishment. Stresses such as these could potentially cause the disappearance of some plant species important for quality deer habitat. Consequently, deer biologist typically quantify the most palatable browse plants in an area in an attempt to monitor browsing pressure by the local deer herd. Sound deer management decisions can be made by recording browse plant use by white-tailed deer.

In any area, three classes of browse plants exist: first choice, second choice, and third choice. As you would expect, first choice plants are those that deer relish — the ones they look to consume first. Third choice are plants deer really do not care to eat. These third choice plants are foods deer can eat, but they choose not to unless first and second choice plants are unavailable.

Second choice browse plants offer the most information about the local whitetail herd. First choice plants almost always show heavy browsing, unless there are very few deer in the area. On the other hand, third choice plants are often used very little, unless the number of the deer in an area has greatly exceeded the carrying capacity of the property. Monitoring the consumption of second choice browse plants by white-tailed deer gives landowners interested in deer habitat management the best information. Here are browse plant preferences for South Texas by preference:

First Choice – Coma, Cedar Elm, Southwest Bernardia, Four-wing Saltbush, Guayacan, Granjeno, Manzanita, Sugar Hackberry, Texas Kidneywood, Vine Ephedra

Second Choice – Anaqua, Anacahuita. Blackbrush, Brasil, Catclaw Acacia, Cenizo, Colima, Guajillo, Hog Plum, Huisache, Little Leaf Sumac, Live Oak, Lotebush, Palo Verde, Ratany, Retama, Texas Ebony, Twisted Acacia, Woolly Bucket Bumelia, Wright Acacia

Thrid Choice РAgarito, Allthorn, Amargosa, Coyotillo, Creosotebush, Desert Yaupon, Green Condalia, Honey Mesquite, Knifeleaf Condalia, Mountain Laurel, Narrowleaf Forestiera, Shrubby Blue Sage, Texas Persimmon, Whitebrush, Wolfberry

This list of important woody plants for white-tailed deer in South Texas should be used as an example of the information available to those interested in producing high-quality deer and habitat. Find this information for your area in publications or by contacting a biologist at your local department of natural resources.
