Overview

• The Key Largo tree cactus was discovered in 1992 and had a population of about 150 stems in the Florida Keys.
• Rising sea levels, intensified storms, and saltwater intrusion led to the cactus's demise.
• The last six stems were salvaged in 2021 for cultivation to prevent total extinction.
• Researchers warn this extinction signals potential future losses for other coastal plants.
• Conservation efforts are underway to replant the cactus in controlled environments.
