If you watch the evening ABC news with David Muir, this story ran 2 days ago, the Falling from trees Iguana Forecast. CNN ran the story included below, and it really is true.
The first year I moved to Florida we had a few days of very very cold weather and the same forecast made the news. Not something you see everyday. I didn't really believe it until I read all the science behind why this happens.
When we lived in Panama, iguanas were part of the landscape, especially on our grandparents farm, Linda Vista. We saw them often, we did not bother them and they did not bother us.
In South Florida they are considered an invasive species; not native to the local ecosystem and causing harm. They can harm the environment, the economy and even human health.
From stories I've read and heard, in south Florida iguanas invade residential areas and eat up all the plants and flowers and come in large groups. I never saw that in Panama.
Nature and man, always something going on.
