The Green Iguana Must Leave the Cayman Islands by Elaine A. Powers, Author

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.

If you’re interested in learning the differences between the native rock iguanas and green iguanas, Lyric Power Publishing produced booklets to help the people of the Cayman Islands differentiate the lizards. Contact Elaine Powers at iginspired@gmail.com to make arrangements to receive some copies.

And, if you’d like to learn more about these fascinating reptiles, click on the workbook below, My Unit Study on Iguanas. It has all kinds of information on iguanas, and pages to Label the Parts, Cut and Paste, True or False, Compare Traits, Cut and Classify, Mean, Mode & Median, and much more! It’s a veritable workbook delight!

Today is Math Storytelling Day! by Elaine A. Powers, Author

The population of the endemic Sister Island Rock Iguana (Cyclura nubila caymanensis) on Cayman Brac is in serious decline.

Math was not my favorite, nor my best, topic, but I did like the math used to solve real-world problems. I enjoyed using geometry to determine how tall a tree is. Discovering the unknown variables in algebra fascinated me; it was like a secret code that had to be deciphered. I eventually came to understand how to use statistics and calculus in measuring aspects of ecosystems and in animal behavior. It turned out that I did like math–if it applied to my interests in science!

When master educator Marilyn Buehrer designed the Lyric Power Publishing workbooks and activity sheets based on my children’s storybooks, I was thrilled that she included some of my favorite animals in her math problems. I particularly like the one where she has the students measure the iguanas to determine average and median sizes in the workbook My Unit Study on Iguanas. I could use that in my citizen scientist work out in the field with the rock iguanas of Cayman Brac!

If you’re curious at all about the Sister Isle Rock Iguanas on Cayman Brac, check out my poignant book, Silent Rocks, pictured above. The population of Cyclura nubila caymanensis on Cayman Brac is in serious decline and these vegetarian lizards are an important part of the island’s ecosystem. Their reduction is the result of human activity on their habitat, and the threats can only be eliminated by human action. I am hopeful the people of Cayman Brac will turn this sad situation around.

In The Dragon of Nani Cave, the Lime Lizard Lads, curly-tail lizards of Cayman Brac, seek an adventure up on the bluff. Their goal is to reach Nani Cave and meet the dragon that lives there. (The dragon is a Rock Iguana, but when you’re a small lizard, an iguana is a dragon!) Gene and Bony soon realize how big and how dangerous the world beyond their beach really is. Leaving home is easy, but what if they do find the dragon? And how will the lads make it back?

Fourteen pages are taken directly from The Dragon of Nani Cave, with 14 pages of corresponding questions. Teachers and parents read the book aloud to students, then hand out the reading and question pages. Students reread pages from the book and answer the questions for each page; they also color in the black and white pictures on every page.
