鈥淏urns can be conducted during the dormant season or growing season accordingly and, when used in proper scale and frequency, can attain a wide collection of land management objectives. Another added benefit of controlled burning is the reduction of fire hazards and fuel loads, lowering the chance of wildfires.鈥
Land managers who are burning for quail have additional factors to consider.
鈥淚f you鈥檙e focusing on quail management, distribution of burn units is even more important as they have a smaller home range,鈥 Mitchell said. 鈥淏urning, while practically mandatory for bobwhite management, also removes cover and exposes the quail to avian predation. The primary raptor migration extends through March in many areas and can impact quail significantly if considerations for sufficient cover aren鈥檛 addressed.鈥
Mitchell said those burning in longleaf pine habitat need to have certain considerations of the new growth on the trees.
鈥淵ou want to burn longleafs before they candle out and start putting on new growth,鈥 he said. 鈥淭he buds, sometimes termed candles, are more susceptible to fire damage during this candling period. Although the longleaf is a very fire-tolerant tree, it can be damaged during this time. After a year of growth, longleafs can typically tolerate properly applied fire. However, if specific burn parameters aren鈥檛 present to burn, significant damage can occur to the saplings, so these burns need to be conducted carefully.
鈥淏ut it鈥檚 critical to get a fire in longleaf stands to suppress the competition from vegetation and other trees, including loblolly pine, especially if you鈥檙e managing for wildlife. You want to maintain that open understory. There鈥檚 not much better habitat than that provided by young longleaf stands for bobwhite quail. You can have nesting and brooding habitat in the same patch of trees.鈥
Mitchell said just about all wildlife benefit from controlled burns in one way or another, even including deer.
鈥淢ost people don鈥檛 think about deer benefitting from burns, but they do,鈥 he said. 鈥淥f course, turkeys and quail benefit, as well as most game birds.
鈥淏urning is the most economical and effective way to manage early successional habitat. After a burn, a lot of the plants that come back are the forbs and legumes and grasses, which are beneficial for most of our wildlife. There鈥檚 a lot of protein in native plants that grow back after a prescribed fire.鈥
Mitchell said studies have shown that turkeys and quail prefer areas with a burn management program, from freshly burned to areas that have burned within 3 years. After 3 years without a burn, the habitat becomes less preferred by turkeys and quail.
鈥淚f the area has a fire history that has been established and maintained, most of the turkey nests will not be in the areas that haven鈥檛 been burned within the past three years,鈥 he said. 鈥淭he nests are going to be in cover that was burned last year or the year before. The plant structure in those units that have been burned is their preferred habitat.
鈥淵ou may have seen it with turkeys; the smoke hasn鈥檛 even cleared and they鈥檙e already out there scratching around.鈥
Mitchell said when areas that have burned get rainfall, the new growth could be popping up within a couple of weeks, and within a month enough cover is available to hide the animals. He said most wildlife habitat is on a one- to three-year burn rotation with the shorter frequency yielding more forbs and grass and less of a woody component and vertical structure. He said burn frequency is site specific.
鈥淥n poor soils, you might need to wait three years between burns,鈥 he said. 鈥淚n rich, heavy soils, ground cover may get too dense too quickly. You may need to tighten that interval or stay on that two-year burn cycle.
鈥淲hen conducted properly, burning improves plant species composition and structure for ground-nesting birds. It reduces that litter layer. It increases the bare-ground component for wildlife movement and foraging. It promotes a lot of flowering and seed production, which increases insect abundance. For your young quail chicks and turkey poults, insects are crucial for their survival in the first couple of weeks to a month after they hatch out.鈥
Another aspect of fires that Mitchell said is often overlooked is that the activity may reduce nest predation.
鈥淥n upland areas with a good fire rotation, you鈥檙e going to reduce the woody or hardwood component and dense vegetation conditions that the predators like to hunt and keep them in hardwood bottom,鈥 he said. 鈥淚t reduces time the predators are in upland areas where turkeys and quail are nesting.鈥
Mitchell said the scale of the area to be burned is also important, with 50 acres considered about the ideal size. If the fire is too large, the turkeys and quail will use the area less.
鈥淵ou want to burn in a checkerboard pattern to maintain an interspersion of burned and unburned habitat,鈥 he said. 鈥淚t鈥檚 been shown that turkeys don鈥檛 use burned areas over 250 meters from the edge of an unburned area until later when cover grows back to a certain level. If you can鈥檛 burn in a checkerboard pattern, burn in a linear shape so the wildlife will have access to adjacent unburned cover.鈥
Mitchell said land managers must give a lot of consideration to neighbors, roadways and whether the land has proper fire breaks and other safety aspects before trying to conduct a controlled burn. Humidity also plays a big factor on whether to burn. If the humidity falls below 30 percent, Mitchell said burning can become a little more dangerous. Many other parameters are also considered to safely and effectively conduct a controlled burn, and it is crucial to have the proper training.
鈥淵ou need to know what you鈥檙e doing,鈥 he said. 鈥淭here are classes you can take. The 黑料天堂 Forestry Commission offers a four-day course for burn manager certification where people get a higher level of fire education and become much more comfortable with applying fire to their property.鈥
Mitchell considers a proper burn regime one of the most beneficial practices wildlife managers can utilize.
鈥淔or wildlife management, prescribed fire is the most effective and cost-efficient tool in the toolbox,鈥 he said.
