Tandy Hills Natural Area is a 210-acre indigenous remnant prairie located in Fort Worth, Texas. The land was obtained by the City of Fort Worth in 1960 and designated a natural area in 1987. Noted for its unusually complete collection of prairie flora, THNA contains more than 1200 native species. The show of spring wildflowers is unsurpassed in the Dallas–Fort Worth metroplex. The land is a living demonstration of how most of Fort Worth appeared in predevelopment times.
