Since the beginning of the year, nearly 48,000 green iguanas have been culled in the Cayman Islands, with the goal of reaching 100,000 by December. Authorities estimate that the iguana population has fallen to less than 100,000, down from 1.4 million in 2018. The program continues, although the remaining animals are becoming increasingly difficult to capture. Green iguanas, which are not native to the archipelago, pose ecological problems.
