Delineation of seagrass die-off in Florida Bay, and location and die-off status of study sites. (A) Spatial extent of turtlegrass die-off 1987–1991 (yellow dashed line) and severely affected areas (red) as adapted from Robblee et al.¹¹. (B) Four basins were selected as study sites (RAN: Rankin Lake, JON: Johnson Key, WHP: Whipray, and RBK: Rabbit Key). Within each basin (hexagonal areas) die-off was categorized into zones: “severe” (red), “patchy” (orange) and “unaffected” (black) based upon patterns of seagrass cover and frequency of seagrass occurrence (see Materials and Methods).
