I was recently on the island of Grand Cayman. This island located south of Cuba has its own native rock iguana, the blue iguana, (Cyclura lewisi). Unfortunately, the invasive green iguana (Iguana iguana) was introduced by humans and their population exploded. In 2018, the estimated green iguana population was about 1.3 million on the 76 square miles of the island. That’s about 18,000 per square mile!
The Cayman Island Department of the Environment initiated a culling program, paying $5 for every green iguana caught and turned in to the DoE. In September 2019, the DoE reported that 925,000 had been removed from the environment.
Last year, when I visited Grand Cayman, greens were everywhere. So I was thrilled this year that I only saw one. The young green was hanging out in the parking lot of the hotel. Despite my affection for green iguanas, they don’t belong in the Cayman Islands and need to be removed. It’s unfortunate that we humans introduced them in the first place. Now, this is the only way to save the native ecology.
Keep up the good work, Caymanians.
