The Sebastian City Council passed Resolution No. R-11-18 on September 14, 2011 to establish the City of Sebastian Champion Tree Program. The program is fashioned after the Champion Tree Program created by the American Forests organization in 1940. Their goal is to recognize the largest known tree of each species in the United States. Every two years American Forests publishes their National Register of Big Trees.
The Florida Forest Service website maintains a list of Florida Champion Trees. Many of the Florida Champion Trees are also national champions. Only native and non-invasive naturalized tree species are eligible for consideration.
