Restoring Fire to Native Landscapes

We support the safe and ecologically appropriate use of fire in Florida, where almost 70 percent of the state’s 9 million acres of public conservation land depend on fire to maintain its diversity of plant and animal life. Private landowners are important partners, as many of their lands require fire as well.

Fire Program Hits "Million" Milestone

TNC's Florida fire program started in 1979. Since then, the chapter has led or participated in over 3,500 controlled burns on over 220 sites working with a wide variety of agency, private and non-profit partners to achieve 1.5 million acres safely burned, resulting in healthy, diverse and resilient landscapes that also reduce the intensity of large wildfires.

Long ago, when Florida was free of roads and houses, fire was a normal occurrence. Bolts of lightning would start a fire that meandered along, stopping at rivers or wetlands. This natural pattern has since been interrupted by the steady growth of development, often cutting through fire-dependent landscapes. As a result, some conservation lands have not been burned for decades. So, TNC's Florida Fire Team will lead or assist with prescribed fires (also called controlled burns) to help keep nature in better balance, restoring the regenerative and vital process to the land.

Fire can also help keep non-native, invasive species in check and natural areas from becoming overgrown. Regular prescribed fire may reduce the intensity of a wildfire by reducing fuel loads such as dead limbs and leaves.

The Burn Begins

Prescribed fire is conducted by a team of highly skilled and experienced professionals. A “burn boss” organizes and supervises the event based on a written plan and schedule. Strict safety procedures protect the crew, nearby residents and private property. Conditions such as weather, wind and drought factors factors are monitored continuously by the Burn Boss, and must be within the parameters of the Prescription before the burn is implemented. Chelsea MacKenzie, the Land Management Specialist for the Central Florida Program, explains the process in the video below.

Some staff will light a line of fire using drip torches or other ignition devices. Others drive trucks carrying supplies and water to be used to control or supress fire. ATVs and even helicopters or trained horses may be on site, along with specialized tools. All of this equipment allows for the careful application of fire and water at the right time, resulting in the fire being “shepherded” across the Burn Unit.

Native plants rebound

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.

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 two percent of a once-magnificent southeastern United States forest remains. Prescribed fire keeps the system alive.

What challenges to implementing fire does TNC address?

1. Training: TNC employs the best trainers to groom and mentor fire leaders, using classroom work and field experience to lead federal fire courses, as well as fire training for private landowners.
2. Policy: Having strong laws and rules in place that protect the act of implementing fire safely within Florida’s lands is critical to the controlled burning success that Florida has demonstrated over many decades. TNC works at the Government Relations level with agency directors and legislators to promote fire’s benefits to both the natural lands and public safety.
3. Education: Some Florida residents–especially newcomers–are unaware of the natural role that fire has played in this state, or they may be concerned about smoke. TNC gives public presentations and informs the media on these issues.

Partnerships are critical to success

TNC is one of only a few nonprofit organizations that adheres to National Wildfire Coordinating Group fire qualifications, allowing our fire crews to collaborate on controlled burns with federal, state and local agencies. TNC also cooperates with other groups in Florida and the Caribbean.
