Growing Season Prescribed Burns Benefit Turkey Habitat

HOT SPRINGS, Ark. -- Forest managers have long known that prescribed fire used to aid with land management is an important tool to improve wildlife habitat. While many prescribed burns are conducted during the dormant season, or winter, there are benefits to extending the activity into the growing season.
The concern expressed by some is the effect of prescribed burns on ground nesting birds, specifically wild turkeys. March and April are generally known as wild turkey nesting months. Forest managers say that burning during this time is much more beneficial than harmful to wild turkey populations.Low ground cover provides forage opportunities and concealment for young poults.
“A common misconception is that prescribed burns during March and April are detrimental to wild turkey populations because they burn wild turkey nests,” said Ouachita National Forest Biologist Clay Vanhorn. “While we do the bulk of our prescribed burning prior to turkey nesting season, we have learned that prescribed fire during growing season is an important tool in creating the improved nesting and brood habitat that turkeys require to thrive.”
Burning during late March and April — when shrubs and saplings start to bud — is much more effective at reducing brush and saplings and stimulating grass and flowering plant growth than winter burning. Hunters know, and research shows, that the lush, new plant growth resulting after a prescribed burn attracts a multitude of insects and provides food and shelter for growing turkey poults. Conversely, if prescribed burns are not implemented, the result is less favorable habitat, a decrease in young poult survival, and eventually a decline in the turkey population.
Two to three years after the prescribed burn, the habitat is prime nesting for hen turkeys. “Hens prefer nesting in prescribed burn areas in the 2-3 years after the initial burn. The vegetation during this period is not too thick, but it has grown enough to provide adequate cover for the nests and young poults,” said Matt Anderson, Ozark-St. Francis National Forests Wildlife Biologist. “Since hens prefer this type of habitat, many of them are not nesting in the thicker, denser areas that are generally the target for prescribed burning during March and April.”
Historically, spring is the time for cleansing fires in nature. Before humans began focusing on fire suppression in wildlands, spring lightning storms ignited fires that eliminated brush and opened forests up to new growth. This resulted in a more fire resistant forest and enhanced habitat for wildlife at the same time. Today, forest managers work to mimic nature’s original forest health cycle with planned prescribed burns.
According to Vanhorn, turkeys, like many animals in Arkansas and Oklahoma forests, adapted to natural, periodic fires. “This has been happening for as long as we’ve had forests. We’re restoring an important component to an ecosystem that evolved with fire. It’s very common to see turkeys feeding on acorns and insects within hours of a prescribed burn, even with brush and grass still smoking around them.”
A position paper by the National Wild Turkey Federation (NWTF) supports the practice. “While the loss of wild turkey nests to prescribed fire is a legitimate concern, a majority of wild turkey research shows very few turkey nests are lost directly because of springtime burns. Research suggests that hens prefer nesting in areas that have been burned within the past two years, but not in high numbers in unburned areas because the habitat is too thick. For the few nests that are lost due to habitat management activity, predation, or even weather-related events, it’s important to note that hens may re-nest up to three times.”

The mission of the U.S. Forest Service, an agency of the U.S. Department of Agriculture, is to sustain the health, diversity and productivity of the nation’s forests and grasslands to meet the needs of present and future generations. The agency manages 193 million acres of public land, provides assistance to state and private landowners and maintains the largest forestry research organization in the world. Public lands the Forest Service manages contribute more than $13 billion to the economy each year through visitor spending alone. Those same lands provide 30 percent of the nation’s surface drinking water to cities and rural communities and approximately 66 million Americans rely on drinking water that originated from the National Forest System. The agency also has either a direct or indirect role in stewardship of about 900 million forested acres within the U.S., of which over 130 million acres are urban forests where most Americans live.
