Florida Fire Helps Forests

The Nature Conservancy supports the safe and ecologically appropriate use of fire in Florida, where almost 70 percent of the state’s 9 million acres of conservation land depends on fire to maintain its diversity of plant and animal life.
Long ago, when Florida was free of roads and houses, fire was a normal occurrence. Bolts of lightning would start a wildfire that meandered along, stopping at rivers or wetlands. Many native plants and animals still require regular fire for survival – just as they need rain and sunshine.
However, human development has interrupted this natural pattern. Some conservation lands may not have burned for decades. So The Nature Conservancy’s Florida Fire Team performs prescribed fires (also called controlled burns) to help keep nature in better balance.
Fire helps keep non-native, invasive species in check and natural areas from becoming overgrown. And, regular prescribed fire may reduce the intensity of a wildfire by reducing fuel loads such as dead limbs and leaves.
Prescribed fire is conducted by a team of highly skilled and experienced professionals. A “burn boss” organizes and supervises the event around a written plan and schedule. Strict safety procedures ensure the safety of the crew, nearby residents and private property, and conditions such as weather, wind and drought factors must be just right.
Some staff will light a line of fire using drip torches. Others drive trucks carrying supplies and water to be used as a control agent. ATVs and even helicopters or trained horses may be on site, along with specialized tools.
Florida Fire Manager Zach Prusak has many stories about some of the Conservancy’s most flamboyant characters and fascinating work.
Thousands of Florida’s key animal species depend upon fire. These include:
During a fire, as many as 40 species take refuge in gopher tortoise burrows. These wide, cool burrows average 15 feet long and 6 ½ feet deep. Other species escape danger in their own way.
After a controlled burn, a blackened field quickly revives with new, green life. Pitcher plants, many orchids, cutthroat and wiregrasses are among key species that thrive upon fire. Indeed, hundreds of Florida’s plant species would be lost without it. See a slideshow.
Longleaf pine is the perfect example. Its life cycle begins when fire prepares the soil for a pine seed to germinate by clearing the ground and turning leaves, dropped pine needles and sticks into fertilizer. For years a young seedling looks like a fuzzy pipe cleaner, its bud protected by tight needles while it grows a deep taproot. A second fire frees the bud and a tree quickly shoots high into the sky, above the fire line. Fire literally stimulates the next generation of this fabulous tree.
A longleaf pine forest is one of the most endangered systems in North America; only 2 percent of a once-magnificent southeastern United States forest remains. Prescribed fire keeps the system alive. See a video about why we burn in North America.
The Conservancy owns approximately 61,000 acres of Florida conservation land, much of which needs fire. In 2010, the Florida Fire Team burned 7,478 acres of these sites, including:
Conservancy teams also assist conservation partners who may lack experience or crews. In 2010, they helped tackle challenging projects on 133,551 acres, from base camps at:
The Nature Conservancy is the only nonprofit organization that is a National Wildfire Coordinating Group partner, able to collaborate on controlled burns with federal, state and local agencies. The Conservancy also cooperates with other groups in Florida and the Caribbean.
Prescribed fire is a valuable tool to help preserve the diversity of life on Earth – now and for future generations. Have we kindled your interest?July 31, 2013
