Islamorada’s Record-Breaking Gumbo Limbo Tree: A Champion in More Ways Than One.
Tucked away in the peaceful shade of Green Turtle Hammock Nature Preserve, home of Florida Bay Forever, stands a tree of epic proportions – literally. Recognized as the largest known gumbo limbo (Bursera simaruba) tree in both Florida and the nation, this leafy giant officially earned the title of Champion Tree on August 24, 2021, a designation bestowed by the American Forests organization. Since 1940, the American Forests Champion Tree Program has celebrated the biggest specimens of each tree species across the United States. To claim the crown, a tree must achieve the highest combined score for height, trunk circumference, and crown spread. Islamorada’s superstar gumbo limbo scored an impressive 179 points, thanks to its towering presence and lush, well-formed canopy.
Though the tree has been known to a few locals for years, its rise to national fame wouldn’t have happened without the dedication of longtime environmentalists Jim and Janice Duquesnel of Key Largo. During a stroll through the preserve about six years ago, the couple decided it was time to nominate the gumbo limbo for Champion Tree status. Jim, a state biologist with decades of conservation experience, first encountered the tree in the early ’90s. His wife, Janice, served the Florida Park Service protecting underwater habitats and was honored with the Distinguished Service Award in 2020. Together, they’ve spent their lives championing Florida’s wild spaces – so it’s only fitting they helped champion this tree.
In 2020, Jim noticed that a pitch apple tree (Clusia rosea), though native, had begun growing around the gumbo limbo’s base, posing a threat to its health. He alerted Islamorada’s Environmental Resources Manager, Pete Frezza, who, along with Florida Forest Service forester Mark Torok, took action. Their combined efforts ensured the tree stayed healthy and earned its rightful place on the National Register.
On March 1, 2025, a plaque was installed at the base of the Champion gumbo limbo. It reads: “In honor of Jim and Janice Duquesnel for their dedication to preserving the natural environments of the Florida Keys.” It’s a tribute not only to a tree but to two people whose tireless work has helped keep Florida’s wild beauty alive for generations to come.

Gumbo limbos are iconic to Florida, often dubbed the “tourist tree” because of their peeling, sunburnt-looking bark—a humorous nod to visitors who’ve had a bit too much sun.
