Authorities say six homes in Santa Rosa County were briefly evacuated and a truck was destroyed due to a brush fire.
Fire officials say the blaze started Sunday afternoon when strong winds spread flames from wood mulch piles.
A spokesman for the Florida Division of Forestry says more than 150 acres burned. Nearly 90 percent of the fire was extinguished Sunday night.
An unidentified volunteer firefighter was treated at a local hospital for heat exhaustion and released.
Firefighters from 17 departments in four counties helped fight the blaze.
