MONROE COUNTY — With local water temperatures dropping significantly in the past several weeks, some Florida Keys coral restoration groups will resume out-planting corals in the coming days and weeks.

Many of the coral restoration practitioners suspended planting of nursery-grown coral along the Florida Reef in the summer because of concerns of another bleaching event, similar to the devastating one in the summer of 2023. The optimal temperature range for corals is 73.4 to 84.2 degrees Fahrenheit. When the water temperature rises above the range, corals experience heat stress and expel the algae that live in their tissues that provide the colonies with nutrients and color.
