In the late 1800s, the land now known as Pine Jog was owned by prominent businessman Henry M. Flagler. From 1893 until 1929, Flagler’s company, the Model Land Company, managed the property. In March of 1929, the land, including Pine Jog, was put up for sale in the West Palm Beach Court House, and control passed to the Lake Worth Drainage District in 1930. In the years that followed, the land was occupied by a few “squatters” and used for farming, as well as open range grazing. To ensure the land’s fertility, local cattlemen burned the property annually to stimulate growth of tender forage for the cattle and eliminate competition from other plants. This practice had a major effect on the natural vegetation of the property.
